We just released a new version of the thirdweb package which unlocks ecosystem wallet support for React Native applications.

You can now connect to any ecosystem wallet from native mobile apps with the same API as the web:

import { ecosystemWallet } from "thirdweb/wallets";
 
const wallet = ecosystemWallet("ecosystem.your-ecosystem");
 
await wallet.connect({
  client,
  strategy: "google", // or any auth method
)};

This means you can now build up a network of web AND mobile apps that all share the same user identity, all while staying within your ecosystem.

Happy building!

In this release, we’ve introduced key enhancements to ABI resolution for composite contracts, improved functionality for managing contract metadata, and made updates to our persistence layer to ensure more robust performance.

We've refactored the ABI resolution process, focusing on better handling of composite contracts like plugin-pattern, base router, and diamond pattern contracts. This included ensuring extra stability by introducing checks to prevent recursive calls and other redundant resources-heavy mechanics.

• Improved the schema for better handling of proxy contracts.
• Added functionality to refresh contract metadata across all persistence layers, simplifying data management.
• Updated persistence-related functions for better error handling and performance, especially in scenarios involving proxies and non-proxy contracts.
• Improved build times and dependency management (could this hint at something bigger, perhaps even... open-sourcing the project s00n? 👀)

With these updates rolling out we get faster ABI resolutions and even more reliable contract data persistence!

• ThirdwebManager inspector is a little more interactive now.

• Improved default redirect page visuals when logging in with OAuth from desktop platforms.
  • Added option to override said html with your own.
• Option to bypass WalletConnect context checks by @BoysheO in https://github.com/thirdweb-dev/unity-sdk/pull/216
  • You now have the option to bypass WalletConnect Unity default synchronization context check as needed by setting
    AppContext.SetSwitch("IsSkipWalletConnectSyncCtxCheck", true);
• ThirdwebClient.Create no longer takes in raw headers, now only takes in general sdk information optionally. This should not affect most users.
  • Improved http client cloning when needed in external modules.
  • Added CrossPlatformUnityHttpClient class which encompasses default .NET and WebGL ones.

We have made some improvements with respect to prebuilt contract deployments on ZkSync chains.

While it doesn't change the deployment process and experience for most users, there are some key changes as described below:

• All thirdweb contracts can now be deployed on any ZkSync chain without any intervention from us, for existing and new ZkSync chains in the future
• All contracts deployed that way are auto verified using standard solc metadata, which means you can view source and interact with them on the dashboard even if they're not verified on block explorers

We've added a new endpoint to Engine that retrieves and parses transaction logs.

• Get Transaction Logs Endpoint: Retrieve logs for mined transactions using a queue ID or transaction hash.
• Automatic Log Parsing: Raw logs are parsed into structured event data by default.
• ABI Inference: The endpoint infers the ABI for verified contracts or those with similar available sources.

• Instant Insights: Get quick information like token transfer amounts or minted NFT IDs without manual log parsing.
• Less Boilerplate: Say goodbye to writing repetitive ABI handling and log parsing code.

Make a GET request to the new endpoint with the following parameters:

• chain: The chain ID or name (required)
• queueId or transactionHash: Identifier for the mined transaction
• parseLogs: Set to true to receive parsed event data (default: true)

For more information, you can check our API Reference.

• Works with verified contracts or those with inferable ABIs, can be overridden back to user provided ABI.
• Parsing is attempted for all logs, providing structured data when possible.
• Falls back to raw log data when parsing is not feasible.

• Easily retrieve information like how many ERC20 tokens were transferred in a transaction.
• Quickly find out the tokenId of an NFT you just minted using Engine.
• Anywhere else you've wanted to quickly access transaction logs without 100 lines of boilerplate code!

thirdweb Engine is an open-source server for your app to read, write, and deploy contracts at production scale. Self-host for free or get a cloud-hosted Engine for $99/month.

The small team at thirdweb is on a mission to build the most intuitive and complete web3 platform. Our products empower over 70,000 developers each month including Shopify, AWS, Coinbase, Rarible, Animoca Brands, and InfiniGods.

See our open roles. We’d love to work with you!

All cloud-hosted Engine instances (running v2.0.10 or later) can now configure alert notifications to be notified when an issue is detected on your Engine instance.

1. Navigate to the new Alerts tab on the Engine dashboard.
2. Select Create Alert.
   1. If the button is disabled, see below.
3. Select the type of alert and how to be notified. Currently the following are supported:
   1. Alert types: Elevated 5xx rate, stuck nonce
   2. Notification types: Webhook, Slack, Email
4. Select Add Alert.

At this time only the original admin (the account which deployed the cloud-hosted Engine) can view and manage alerts. This is usually the first admin address listed on the Admins tab. We plan to expand alert management to all admins in the near future.

You can also view recently fired/resolved alerts on the Alerts tab.

This feature lays the groundwork for advanced notifications for any type of error or event that Engine can emit.

For instance, in the future Engine can monitor the balance of a wallet and alert when it drops below a specified threshold. Or alert when it detects unusual transfer activity from a backend wallet.

TypeScript SDK

All Ecosystem Wallets are now stored and accessed within AWS Nitro Enclaves. This evolution of wallets provides improved security, speed, and capabilities. The migration to enclaves happens behind the scenes and without any changes necessary.

Upgrade to the latest version of the thirdweb SDK and each ecosystem wallet will be upgraded on next login. In the coming days and weeks we'll be adding additional capabilities that are unlocked by enclaves, the first of which is pregeneration.

You can now pregenerate user accounts via the in-app wallet backend APIs. This allows for interacting with accounts before their owner has logged in. For example, you might send some funds to a user's email, and pregenerate their account if they don't have one yet.

curl -X POST 'https://embedded-wallet.thirdweb.com/api/v1/pregenerate' \
  -H 'x-ecosystem-id: ecosystem.example-eco-123' \
  -H 'x-secret-key: 9f8e7d6c5b4a3f2e1d0c9b8a7ffge434b2a1f0e9d8c7b6a5f4e3d2c1b0a9f8e7' \
  -H 'Content-Type: application/json' \
  -d '{
    "strategy": "email",
    "email": "user@example.com"
  }'

Response format:

{
  "wallet": {
      "address": "string",
      "createdAt": "string",
  }
}

Coinbase is now supported as an in-app and ecosystem wallet authentication method.

import { inAppWallet } from "thirdweb/react";
 
const wallet = inAppWallet();
 
const account = await wallet.connect({
  strategy: "coinbase",
  chain: mainnet,
  client: thirdwebClient,
});

With v5.45, we introduced linking multiple authentication methods to an in-app wallet to create a unified identity. Ecosystem wallets now support this same functionality across all platforms.

import { ecosystemWallet, linkProfile } from "thirdweb/wallets";
 
const wallet = ecosystemWallet("ecosystem.hooli");
 
await wallet.connect({ strategy: "google" });
const profiles = await linkProfile(wallet, { strategy: "discord" });

• isGetNFTSupported checks for getNFT support on an ERC-1155 contract
• Ecosystem wallets now support guest mode

React SDK

• The details modal now displays the currently logged in auth provider
• The details modal now shows user info such as email when logged into an ecosystem wallet
• The social icon arrangement in the Connect UI now overflows to a new line when using more than 5 auth methods

• Guest accounts are now hidden from the details modal linked profiles screen

Get ready for an upgraded experience with our latest release! We’ve exposed key functions for smoother OAuth workflows, enhanced analytics, and provided custom UI examples to supercharge your development process. Plus, with helpful new tools and fixes, creating seamless OAuth flows and managing your game data has never been easier. Dive in and explore the possibilities!

• Expose SecretKey->ClientID function from rust and update rust libs
• Create and send analytics for connect, with opt-out in settings
• OAuthBrowserUserWidget events for custom OAuth UI Scenarios
• Custom OAuth Browser Overlay example with Circular Throbber and Back button
• Set world override on Level_Thirdweb for GameMode to help new devs
• Set EditiorCustomVirtualPath on plugin to help data segregation
• Various helper functions

• Expose FWalletHandle to external access in C++
• Fix White-screen OAuth Scenario in Examples

• Hide OAuthBrowserWidget from editor

Marketplace | Documentation | Github Release

• Ecosystem Wallets implementation in .NET is now compatible with our previous JS implementation of Ecosystem Wallets.
  • If you had created accounts or had a user base from web sharded Ecosystem Wallets, they will automatically be migrated to the new performant enclave system upon first login.
  • No breaking API changes here, this change detects if an authenticated user requires migration and performs it.
• ERC721 and ERC1155 NFT Contract Extensions such as _GetAll and _GetOwned now have default pagination (100 first token ids).
  • This is to avoid fetching an entire collection at once by mistake.
  • If the contract is ERC721A, tokensOfOwnerIn will be used before falling back to other extensions.
  • If the contract is ERC721Enumerable, tokensOfOwnerByIndex will be used before falling back to single fetching.
  • Improved batching of such calls.
• Implemented ConcurrentQueue for RPC and improved batching/caching logic
  • If you do end up making large calls, such as fetching an entire collection, it should be handled gracefully
  • Avoid a lot more 429s
• Speed up Smart Wallet user operations
  • No longer estimates the entire user operation gas and simulates prior to sending it.
  • This does not affect errors being caught.
  • This means if you are estimating gas using ThirdwebTransaction, you will only be returned the internal call gas limit rather than the entire op.
  • Less API calls at runtime, 30% faster execution.
  • If you still want to estimate the actual user operation gas costs, you can use SmartWallet.EstimateUserOperationGas
• Fixed issue with _MintWithSignature extensions where the expected signature bytes would be passed as hex.
• [Unity Only] Added ToQRTexture helper extension for converting any text to a Texture2D and potentially display it in a UI Image.

An exciting update is rolling out to improve how contract data is handled on our platform, bringing greater efficiency and scalability!

Faster contract-related SDK calls and dashboards

First and foremost, we enhanced the retrieval process for contract bytecodes, proxy implementations, and metadata by introducing an additional persistence layer. This improvement allows us to serve previously processed data much faster without querying external sources.

This leads to reduced routing and quicker response times. Meaning... 👀 better performance when calling your favourite SDK v5 functions like resolveContractAbi() and getBytecode() or when loading a contract's dashboard (e.g. USDC contract) to see ABI, sources and etc.!

Additional Improvements

• Overall stability enhancements through better error logging and improved dependency management.
• Performance boosts through more efficient caching and database query optimizations.
• Codebase refactoring to meet modern standards, enhancing maintainability and scalability.

We are starting to roll out this update incrementally, continuing to prioritise data accuracy while significantly boosting speed!

postscriptum - what is this service about?

Our contract service is a crucial backend tool for managing smart contracts and on-chain interactions within the thirdweb platform and beyond. It streamlines key tasks such as fetching and aggregating comprehensive contract metadata (including ABIs and compilation details) and automates the publishing and verification of contracts on popular blockchain explorers.

By removing the often complex, manual steps involved in contract verification, the service makes it far easier for developers to interact with and deploy smart contracts. We'll be unveiling more information about this service in the future, as we consider making this logic a public good, iykwim ;)

As active development is underway with the Modular Contracts framework, safety and security of the code that we officially release into production is always top of mind at thirdweb.

Which is why today we release macro-audit-8, which covers the following repositories: modular contracts, contracts and contracts pay gateway.

You can find the full release of the audit here.

As Modular Contracts have undergone a significant refactor, we are now going through a second round of auditing in order to cover for those changes, so stay tuned!

Sometimes users want to get started using your app without logging in. You can now give users an in-memory "guest account" that can then be converted into a standard account by linking another auth method.

import { inAppWallet } from "thirdweb/wallets";
 
const wallet = inAppWallet();
 
// Create the temporary guest account
const account = await wallet.connect({
  client,
  strategy: "guest",
});

When your user is ready, link any other auth method so they can access their account in the future.

import { linkProfile } from "thirdweb/wallets";
 
await linkProfile(wallet, { strategy: "google" });

Your user can now access this same wallet with their Google account. Until the user links another profile to the wallet, it will be stored in memory and last until they clear their browser cookies or connect a different wallet.

Guest accounts are available in the Connect UI just like any other authentication method.

import { ConnectButton } from "thirdweb/react";
import { createWallet } from "thirdweb/wallets";
 
<ConnectButton
  wallets={[
    createWallet("inApp", {
      auth: {
        options: [
          "google",
          "discord",
          "telegram",
          "email",
          "phone",
          "guest",
        ],
      },
    }),
  ]}
/>;

• Fixed custom ID handling in custom contracts
• Expand getNFTs ERC1155 support

More and more protocols and chains have been releasing functionality around cross-chain messaging and token transfers. With Modular Contracts being released in beta, we saw this as an opportunity to partner up and create modules around these functionalities.

However, as we explored deeper into each protocol's cross-chain mechanisms, we noticed a significant amount of overlap across all functionalities, including:

• A function to handle sending cross-chain payloads and tokens
• A function to handle receiving cross-chain payloads and tokens
• Setter and getter functions for their version of a router

With that in mind, we decided to create CrossChain.sol, an abstract contract that provides a unified interface to implement cross-chain functionality across any protocol.

Inside the contract CrossChain.sol, there are three main functions:

sendCrossChainTransaction

function sendCrossChainTransaction(
	uint64 _destinationChain,
	address _callAddress,
	bytes calldata _payload,
	bytes calldata _extraArgs
) external payable virtual;

As the name suggests, this is the primary function responsible for sending cross-chain transactions from the protocol.

onCrossChainTransactionSent

function onCrossChainTransactionSent(
	uint64 _destinationChain,
	address _callAddress,
	bytes calldata _payload,
	bytes calldata _extraArgs
) internal virtual;

This callback function is used within the context of the sendCrossChainTransaction function.

onCrossChainTransactionReceived

function onCrossChainTransactionReceived(
	uint64 _sourceChain,
	address _sourceAddress,
	bytes memory _payload,
	bytes memory _extraArgs
) internal virtual;

This callback function is used within the context of the receive function for the specified cross-chain protocol.

With these two callback functions, the user’s application logic can be separated from the cross-chain functionality logic, making it easier to differentiate between the two.

And there you have it—an abstract contract to create a unified interface for cross-chain functionality.

You can now get the admin wallet for a currently connected smart account with useAdminWallet.

import { useActiveWallet, useAdminWallet } from "thirdweb/react";
 
const activeWallet = useActiveWallet(); // smart wallet
const adminWallet = useAdminWallet(); // the personal wallet that controls the smart wallet

The Marketplace contract is one of our most used contract templates, and to make it even easier to build on-chain marketplace experiences we're constantly adding SDK extensions to interact with the Marketplace contract.

To better understand what your specific Marketplace supports, we've added a number of specific functions to check for supported features on a contract prior to attempting to use them.

• isGetListingSupported
• isBuyFromListingSupported
• isCreateAuctionSupported
• isGetAuctionSupported
• isGetWinningBidSupported
• isBidInAuctionSupported
• isCancelAuctionSupported
• isCreateAuctionSupported
• isCancelListingSupported

With the release of Modular Contracts, you now might need to check if a given module is compatible with your core contract prior to installing it. You can now do this using the checkModulesCompatiblity function.

import { checkModulesCompatibility } from "thirdweb/modules";
 
const isCompatible = await checkModulesCompatibility({
  chain: defineChain(1),
  client: THIRDWEB_CLIENT,
  coreBytecode: "0x...",
  moduleBytecodes: ["0x..."],
});

Published contracts are more discoverable, more easily indexed, and more usable across thirdweb's tools than unknown contracts. It allows anyone to pull the contract's ABI and metadata to interact with your contract permissionlessly. You can now programmatically publish any contract to thirdweb's contract registry with publishContract.

import { publishContract } from "thirdweb";
 
const transaction = publishContract({
  contract,
  account,
  metadata,
});
 
await sendTransaction({
  account,
  transaction,
});

• Function signatures and contract ABIs are now properly handled in resolveMethod
• Pay now allows topping up from a different wallet with the same currency
• Our internal ABI types are now publicly exported under thirdweb/utils
• Balances are now properly invalidated on Pay transaction success
• PayEmbed metadata can now be customized

We've completed revamped the API Key settings page with a more polished UI and following UX improvements

• Combined "Edit" and "View" pages to a single simpler page
• Added "Save" button next to all the form groups instead of having a single "Save" button all the way at the bottom of page
• No more hidden fields - Bundle ID restrictions and Domain restrictions are visible directly on page load
• Improved helper text for form fields

• Failover Algorithm Optimization: Enhanced the failover algorithm to improve resource efficiency.
• Error Handling Improvements: Refined error handling for JSON-RPC errors, providing more robust responses.
• RPC Edge Error Logging: Improved logging for RPC Edge, now handling multiple metadata objects and error stacks more effectively.
• Correlation ID for Error Responses: Added correlation IDs to error responses, uniquely tagging each RPC request for easier troubleshooting.
• Lit Protocol Resources: Expanded available resources for the Lit protocol.
• Database Connection Handling: Enhanced management of database connections for better performance.
• Internal Block Staleness Monitoring: Strengthened internal monitoring to detect and address block staleness more proactively.
• Test Coverage: Increased service test coverage to over 90%, ensuring higher reliability.

• RPC Edge Routing Error Rate: Reduced error rates in RPC Edge routing by optimizing node discovery strategy.
• Node-Specific Failovers: Fixed an issue where node-specific errors triggered unnecessary failovers, improving overall system stability.

• Adds AuthProvider.X as a login option. Linking supported.

// Unity - InAppWallet
var iawOptions = new WalletOptions(
    provider: WalletProvider.InAppWallet,
    chainId: 421614,
    inAppWalletOptions: new InAppWalletOptions(authprovider: AuthProvider.X)
);
var iaw = await ThirdwebManager.Instance.ConnectWallet(iawOptions) as InAppWallet;
// Unity - EcosystemWallet
var ecoOptions = new WalletOptions(
    provider: WalletProvider.EcosystemWallet,
    chainId: 421614,
    ecosystemWalletOptions: new EcosystemWalletOptions(
        ecosystemId: "ecosystem.the-bonfire",
        authprovider: AuthProvider.X
    )
);
var eco = await ThirdwebManager.Instance.ConnectWallet(ecoOptions) as EcosystemWallet;
// .NET - InAppWallet (Windows Console Example)
var inAppWalletOAuth = await InAppWallet.Create(
  client: client, 
  authProvider: AuthProvider.X
);
if (!await inAppWalletOAuth.IsConnected())
{
    _ = await inAppWalletOAuth.LoginWithOauth(
        isMobile: false,
        (url) =>
        {
            var psi = new ProcessStartInfo { FileName = url, UseShellExecute = true };
            _ = Process.Start(psi);
        },
    );
}
var inAppWalletOAuthAddress = await inAppWalletOAuth.GetAddress();
Console.WriteLine($"InAppWallet OAuth address: {inAppWalletOAuthAddress}");
// .NET - EcosystemWallet (Windows Console Example)
var ecosystemWalletOAuth = await EcosystemWallet.Create(
  ecosystemId: "ecosystem.the-bonfire", 
  client: client, 
  authProvider: AuthProvider.X
);
if (!await ecosystemWalletOAuth.IsConnected())
{
    _ = await ecosystemWalletOAuth.LoginWithOauth(
        isMobile: false,
        (url) =>
        {
            var psi = new ProcessStartInfo { FileName = url, UseShellExecute = true };
            _ = Process.Start(psi);
        }
    );
}
var ecosystemWalletOAuthAddress = await ecosystemWalletOAuth.GetAddress();
Console.WriteLine($"EcosystemWallet OAuth address: {ecosystemWalletOAuthAddress}");

• Fixes edge case when sending two SmartWallet transactions at once from an undeployed account and using EntryPoint 0.7.0 where deployment code would be duplicated causing an error.

You can now login to an in-app wallet using X/Twitter.

import { inAppWallet } from "thirdweb/wallets";
 
const wallet = inAppWallet();
 
const account = await wallet.connect({
  client,
  chain,
  strategy: "x",
});

This also works for linking accounts to an existing wallet.

import { inAppWallet, linkProfile } from "thirdweb/wallets";
 
const wallet = inAppWallet();
 
await wallet.connect({ strategy: "google" });
await linkProfile(wallet, { strategy: "x" });

We've added a parseNFTUri utility function to parse NFT image URIs of all formats to an IPFS hash. We've also added a parseAvatarRecord function to specifically parse ENS avatars to a usable HTTPS URL.

import { parseAvatarRecord } from "thirdweb/extensions/ens";
import { parseNftUri } from "thirdweb/extensions/common";
 
const avatarUrl = await parseAvatarRecord({
  client,
  uri: "...",
});
 
const nftUri = await parseNftUri({
  client,
  uri: "...",
});

You can now hide specific wallet types in the React wallet switcher UI. This can be helpful if you'd like to use smart wallets without exposing the wallet address to the user, or in the opposite case to hide the underlying admin wallet from the user.

<ConnectButton
  client={client}
  detailsModal={{
    // We hide the smart wallet from the user
    hiddenWallets: ["smart"],
  }}
  accountAbstraction={{
    chain: baseSepolia,
    sponsorGas: true,
  }}
/>;

• Specify your preferred provider on the buyWithFiat function using preferredProvider

LINE is now supported as an authentication method across the SDK.

import { inAppWallet } from "thirdweb/wallets";
 
const wallet = inAppWallet();
 
const account = await wallet.connect({
  client,
  chain,
  strategy: "line",
});

This includes linking an account to form a unified identity.

import { inAppWallet, linkProfile } from "thirdweb/wallets";
 
const wallet = inAppWallet();
 
await wallet.connect({ strategy: "google" });
await linkProfile(wallet, { strategy: "line" });

You can now retrieve users by email, phone number, wallet address, or user ID from the server in a single line of code.

import { getUser } from "thirdweb/wallets";
 
const user = await getUser({
  client,
  email: "vitalik@ethereum.org",
});

You can now use a salt to deterministically deploy published contracts.

const address = await deployPublishedContract({
  client,
  chain,
  account,
  contractId: "Airdrop",
  contractParams: {
    defaultAdmin: "0x...",
    contractURI: "ipfs://...",
  },
  salt: "test", // <--- deterministic deploy
});

This also works with unpublished contracts deployed via deployContract.

const address = await deployContract({
  client,
  chain,
  account,
  bytecode: "0x...",
  abi: contractAbi,
  constructorParams: {
    param1: "value1",
    param2: 123,
  },
  salt: "test", // <--- deterministic deploy
});

Constructor parameters passed to deployPublishedContract are now passed as an object rather than an array.

const address = await deployPublishedContract({
  account,
  chain,
  client,
  contractId: "Airdrop",
  contractParams: {
    defaultAdmin: TEST_ACCOUNT_A.address,
    contractURI: "",
  },
});

• Added support for React Native 0.75
• Fixed ERC721 delayed reveal detection
• Multiple smart wallet transactions can now be sent in parallel
• Added the toFunctionSelector utility
• Social profiles now display in the linked accounts list
• Polygon MATIC is now POL

Over the years, we've seen smart contracts struggle to keep up with developers' evolving needs. Innovation opens new possibilities for asset distribution and compliance, yet deployed contracts remain rigid.

To solve this, we've built Modular Smart Contracts—a framework that allows for highly customizable contracts. Think of these as building blocks: start with a base and add different pieces to create a contract fit to your needs.

Modular Contracts is officially launched with limited deployments, available on testnets only from September 12 - September 26. Post this period, mainnet deployments will be available.

What can you use right now?

• Popular Pre-built Contracts - We've redesigned our top seven contracts using the modular contract framework. These are now available for deployment through the dashboard. Visit Explore to view the available contracts.
• Deploy custom modules - Write and add custom created modules to any ERC20, ERC721, or ERC1155 core contract.
• Connect SDK Support - Once your contract is deployed, use the Connect SDK to build an application. View SDK Integration documentation.

Improvements since alpha

• Creator Token Standard - We worked with Limit Break to create a module that enforces on-chain programmable royalties through transfer security policies. This module is now a default in all thirdweb pre-built contracts utilizing royalties.
• Changes to Claim Conditions - Based on user feedback, we added a start and end timestamp and simplified the module to only allowlist or public phases.
• Simplified modules - Improved composability patterns and simplified modules across the board. View the full changelog.

What’s coming up in the next few weeks?

• Modules UI - Be able to interact with thirdweb enabled modules (upload NFTs, set claim conditions, and more) through the dashboard rather than through the SDK or Explorer.
• Modular Contract Wizard v1- A UI building tool to create contracts combining compatible core and modules.
• Cores & Modules listed on Explore - Discover more modules from other protocols and be able to list modules and core contracts on Explore for your audiences.

Beta Feedback Program

We're excited to invite you to try Modular Smart Contracts and provide our team with direct feedback during a 20-minute call. As a thank you, you'll receive $50 in credit to utilize towards any usage, growth plan, or upgraded instances of Engine. To participate, please sign up to be a tester. We'll then send you more information via email.

This is no exaggeration, our Ecosystem Wallets are now so feature rich there is no use case in all of gaming that it does not support.

Thirdweb now provides you with a cross-platform, cross-sdk, cross-device, cross-language blockchain-powered, secure, non-custodial account system that you can not only reuse across your own games and apps, but also your ecosystem partners' games and apps.

It doesn't stop there, you can use this EcosystemWallet to create a Guest mode (AuthProvider.Guest) first and upgrade later through Account Linking, which we feature here alongside other additions like Line authentication. All of this without losing the EcosystemWallet address.

The Account Linking feature, once understood, unlocks infinite possibilities as it ties into all our auth methods, which now include:

• Email (OTP)
• Phone (OTP)
• Google
• Apple
• Facebook
• Discord
• Farcaster
• Telegram
• Line
• Siwe (Sign in with Ethereum - yep you can link external wallets and even login to your EcosystemWallet with them next time)
• Guest (does not require any inputs, simply choose it as your auth provider to create a guest mode)

It doesn't stop there, we also offer custom authentication:

• JWT (you want to create a wallet out of an OIDC-compatible authentication system, entirely possible)
• AuthEndpoint (you want to go even further, having us verify a generic payload against your backend, for things like TG Mini-Apps)

There is not a single use case we don't support. You just have to integrate, and we're here to help.

If you don't want to commit to a performant, scalable, entirely secure and shareable with third-parties and fast EcosystemWallet, don't worry, all of the above is available for InAppWallet too.

Do note that once again, it's the same API for InAppWallet, but without ecosystemId and the optional ecosystemPartnerId.

Below are the different ways you can use some of the functionality introduced in this version.

You can turn any of these wallets into a Smart Wallet easily, using SmartWallet.Create or by passing SmartWalletOptions to Unity's ThirdwebManager.ConnectWallet function on top of your base options / using the ThirdwebManager.UpgradeToSmartWallet helper if you want to do it later.

var guestWallet = await EcosystemWallet.Create(ecosystemId: "ecosystem.the-bonfire", client: client, authProvider: AuthProvider.Guest);
if (!await guestWallet.IsConnected())
{
    _ = await guestWallet.LoginWithGuest();
}
var address = await guestWallet.GetAddress();

var walletOptions = new WalletOptions(
    provider: WalletProvider.EcosystemWallet,
    chainId: 421614,
    ecosystemWalletOptions: new EcosystemWalletOptions(ecosystemId: "ecosystem.the-bonfire", authprovider: AuthProvider.Guest)
);
var ecosystemWallet = await ConnectWallet(walletOptions) as EcosystemWallet;

var linkedAccounts = await ecosystemOrInAppWallet.GetLinkedAccounts();

All Auth Methods Supported! Just pass the related params to that auth method that you typically would

// Assuming you already have a connected wallet you want to link a new profile to
var walletToLink = await InAppWallet.Create(client: client, authProvider: AuthProvider.Google);
var linkedAccounts = await mainConnectedWallet.LinkAccount(walletToLink );

// Sign up with guest mode to avoid the friction of auth with new users
var walletOptions = new WalletOptions(
    provider: WalletProvider.EcosystemWallet,
    chainId: 421614,
    ecosystemWalletOptions: new EcosystemWalletOptions(ecosystemId: "ecosystem.the-bonfire", authprovider: AuthProvider.Guest)
);
var ecosystemWallet = await ConnectWallet(walletOptions) as EcosystemWallet; // or EcosystemWallet.Create
// This address will not change after linking i.e. in this case "upgrading" your account
var address = await ecosystemWallet.GetAddress();
Debug.Log($"Connected EcosystemWallet: {address}");
// This is how you display currently linked accounts
var linkedAccounts = await ecosystemWallet.GetLinkedAccounts();
Debug.Log($"Linked accounts: {Newtonsoft.Json.JsonConvert.SerializeObject(linkedAccounts)}");
// Create a raw EcosystemWallet to link, in this example user would have chosen to link Line
var ecosystemWalletToLink = await EcosystemWallet.Create(
    client: ThirdwebManager.Instance.Client,
    ecosystemId: "ecosystem.the-bonfire",
    authProvider: AuthProvider.Line
);
// Use the Unity SDK helper to link the accounts
var newLinkedAccounts = await ThirdwebManager.Instance.LinkAccount(ecosystemWallet, ecosystemWalletToLink);
Debug.Log($"New linked accounts: {Newtonsoft.Json.JsonConvert.SerializeObject(newLinkedAccounts)}");

• Improved speed of NFT-related extensions.
• Fixed an issue with SIWE as an AuthProvider when using ThirdwebManager to connect.
• Added contract extensions ERC721A_TokensOfOwner & ERC721A_TokensOfOwnerIn.
• Added optional pagination to all _GetAllNFTs & _GetOwnedNFTs extensions.
• Improved ERC721A NFT-fetching speed.

Our goal at thirdweb has always been to work for game developers - with such systems, you're able to offload all the account system, auth, database, item management, currency management, and analytics work to the blockchain. This is what we do, and we want to help you and listen to feed back - make sure you reach out, we have many programs to get you going!

We have the recipe to make blockchain games unbeatable, cheap, fast, invisible. Persistent In-App & Ecosystem Wallets paired with Account Abstraction, Session Keys and some easy to deploy contracts is what we do. It's all open-source, it's all yours to manage.

It's time to ditch external wallets.

Blockchain games can finally focus on being fun and on distribution across different runtime platforms and companion apps.

We integrated the newly available Social SDK in the thirdweb Dashboard, making it available anywhere wallet addresses are rendered. Simply hover any wallet address or ENS name to see linked social profiles.

React Native now supports Coinbase Smart Wallet with v5.53.0 of the thirdweb SDK. Create a Coinbase Smart Wallet connection using the same createWallet function you know and love:

import { createWallet } from "thirdweb";
 
const wallet = createWallet("com.coinbase.wallet", {
  appMetadata: {
    name: "My app name",
  },
  mobileConfig: {
    callbackURL: "https://example.com",
  },
  walletConfig: {
    options: "smartWalletOnly",
  },
});
 
await wallet.connect({
  client,
});

We've added a createAndSignUserOp function to handle everything involved with turning a set of transactions into a single AA UserOp. Gasless and/or sponsored transactions couldn't be easier:

import { createAndSignUserOp } from "thirdweb/wallets/smart";
 
const userOp = await createAndSignUserOp({
  client,
  adminAccount,
  smartWalletOptions,
  transactions,
});

• Improved common icons in React Native SDK
• Increased storage slots for proxy resolution

Fixed ERC20 balance reading when showing the Pay modal

We made a number of improvements on testing on thirdweb Pay.

1. Added a testMode property to the buyWithCrypto PayUIOptions. This will allow you to filter for all supported testnets and try out a crypto-to-crypto purchase experience without using mainnet funds.
2. Enabled Pay with Fiat on testnet purchases. No funds are delivered in this flow, but the credit card testnet experience will allow you to simulate an end-to-end user journey without requiring an actual credit card purchase.

A few more updates on how the team makes our RPC Edge solution more resilient and flexible!

Initial Node Prioritisation with Default Scoring

While dynamic routing and scoring optimise node selection over time, it's crucial that the system starts off in a reasonable state when the server spins up. To address this, we've now implemented a robust approach for default node prioritisation. The priorities are now designed to be easily adjustable, enabling the team to efficiently re-order or disable certain nodes in case of emergencies or other ad-hoc situations. This step ensures more flexibility and efficiency in managing the initial order of nodes, creating a smoother path for ongoing improvements.

Changes made recently in this regard:

• Node Default Prioritisation: we are now configuring RPC Edge to utilise explicitly set default priorities, supporting granular configurations options (e.g. methods and regions) to ensure that specific node preferences can be applied where needed for the enhanced performance.
• Configuration Schema and Structure: the new schema accommodates the team in efficient management of relevant configuration options, ensuring a clean and scalable system.
• Prioritisation Logic Improvements: sorting and filtering algorithms have been improved and generalised to handle various configurations
• Caching for Performance: in-memory caching for configurations is in place, reducing the load & latency on the system when serving requests for high-load chains.

These changes are being released incrementally as we continue to prioritise the stability and quality of our RPC Edge solution.

You can now query any address's on-chain social profiles using the new social extension in the thirdweb SDK.

import { getSocialProfiles } from "thirdweb/social";
 
const profiles = await getSocialProfiles({
  address: "0x...",
  client,
});

The query will return an array of SocialProfile objects for each profile the address is associated with. This type has a standardized top-level interface of type (farcaster, lens, and ens are currently supported), name, bio, and avatar. You can access protocol-specific user information such as the Farcaster FID under the metadata field.

    "type": "ens",

You can access the same query via the prebuilt React Query hook useSocialProfiles.

import { useSocialProfiles } from "thirdweb/react";
 
const { data: profiles } = useSocialProfiles({
  client,
  address: "0x...",
});

Our ConnectButton component in both React and React Native uses the social SDK to display a users profile rather than their wallet address when available.

• Modular Contract Support - Learn more
• Added test mode to Pay options on ConnectButton - Learn more
• Added getOwnedTokenIds to ERC1155 extension - Learn more
• Added options to hide Buy, Send, and Receive buttons in useWalletDetailsModal - Learn more
• Fixed base URI extraction logic in contract extensions
• Fixed function ID retrieval for contract extensions
• Improved React Query caching performance

We are continuously improving our RPC Edge and the latest update is out!

Dynamic Method Based Scoring and Routing for RPC Edge

We implemented a modular scoring strategy to choose the most performant node for the requests. Edge RPC uses method-based scoring and picks the dominant method within a batch. It also supports scoring and retrying JSON RPC server errors and fails over to other nodes if there is a problem.

Edge RPC will know itself how to choose the best upstream node with 99.9% probability. This change will improve error rate, latency and data accuracy and will only improve over time.

First tests are already showing improved latency by 20%!

Error Handling and Logging Updates

We improved Edge RPC's error handling to better follow the JSON RPC spec. RPC errors are now included in the response body and the Edge RPC always returns HTTP 200 status.

Improved internal metrics and logging around Edge RPC failovers and incomplete responses.

Deprecations
Removed support for deprecated Mumbai RPC.

We will start to roll out the Edge RPC scoring method update incrementally and continue to prioritize data correctness and speed.

We just released v5.52.0 of the thirdweb TypeScript SDK which unlocks the ability to deploy, configure and interact with our new Modular Contracts.

You can now easily build your personalized contract by picking the modules suited for your use case.

Here's how to deploy a ERC721 contract with the Claimable and BatchMetadata module, which together create a Drop functionality.

import {
  ClaimableERC721,
  BatchMetadataERC721,
  deployModularContract,
} from "thirdweb/modules";
 
const deployed = deployModularContract({
   client,
   chain,
   account,
   core: "ERC721",
   params: {
     name: "My Modular NFT Contract",
   },
   modules: [
     ClaimableERC721.module({
        primarySaleRecipient: ...,
     }),
     BatchMetadataERC721.module(),
   ],
});

These modules can be swapped at any time, and new ones can also be added post deployment. Here's how to install a new module programmatically:

import {
  RoyaltyERC721,
} from "thirdweb/modules";
 
const transaction = RoyaltyERC721.install({
  contract: coreContract,
  account,
  params: {
     royaltyRecipient: account.address,
     royaltyBps: 100n,
     transferValidator: ZERO_ADDRESS,
  },
 });
})

We have core contracts for ERC20, ERC721 and ERC1155 standards. Those follow the standard ERCs and can be interacted with like usual with the standard extensions.

The interesting part is to interact with an attached module. This is done by using the defined module name spaced API:

import { ClaimableERC721 } from "thirdweb/modules";
 
const transaction = ClaimableERC721.mint({
  contract,
  to: "0x...", // Address to mint tokens to
  quantity: 2, // Amount of tokens to mint
});
 
// Send the transaction
await sendTransaction({ transaction, account });

This makes it easy to discover the available API for each module.

You will also soon be able to generate the namespaced TypeScript API for your own modules via the thirdweb CLI.

To learn more about modular contracts and how to create modules, head over to the documentation.

All new Engine deployments from the thirdweb dashboard will be on v2.

For existing cloud-hosted Engines, please request a version upgrade in the dashboard. (We're making upgrades self-service very soon!)

The worker architecture in Engine v2 was redesigned with maximum onchain throughput in mind. Users should see:

• Higher onchain throughput: Batches of transactions for a single backend wallet are now fully parallelized. The entire batch will often be sent in the next block, resulting in up to 700x more transactions sent per second, depending on the chain.
• Lower time to send: Slow polling and DB locks are removed. Transactions are processed from the queue as soon as they arrive, resulting in a median of 300ms from Engine receiving a transaction to sending it.

Engine v2 is capable of sending hundreds of transactions per second to a chain's RPC. However the total transactions from a single wallet that a block will accept depends on the chain. Here are some numbers we've seen on a single 1 vCPU / 1 GB memory host:

• B3 testnet: 1500 txs per block
• Base testnet: 65 txs per block
• Polygon testnet: 85 txs per block
• Arbitrum testnet: 100 txs per block

Note: transactions mined per second ~= # transactions per a block / block time

Publicly documented interfaces have no breaking changes. There is no expected changes required from users.

Engine development started 1.5 years ago to power onchain transactions internal to thirdweb. After chatting with other teams, we recognized most teams were spending engineering weeks solving similar problems. Engine was open-sourced in Q2 2023 and we've been iterating on it since.

Engine v1 was designed to send batches of transactions without waiting for previous ones to be mined. This already introduced a lot of challenges around nonce management (see Sending more than one transaction at a time is easy, right?). We've since uncovered dozens of edge cases from internal testing and customer reports across a multitude of chains, contract types, and use cases.

As Engine expanded in scope, so did web3 use cases. We started seeing apps and games use Engine in ways that demanded higher throughput and lower latency. We looked at bottlenecks: DB locks, short polling, batching logic, coupling of dependencies. Leveraging learnings in the past year, we started on v2 to address these bottlenecks.

Engine v2 moves performance-critical and atomic operations from Postgres to Redis queues. This change allows for faster reads and writes to DB leading to less blocking behavior, lower latency, and fewer scaling issues. The code is better organized, typesafe, and built on the thirdweb v5 SDK (which comes with added performance gains).

In v2 transactions no longer block on RPC responses, saving 50-200ms per transaction (very noticeable at scale!). While this change introduced even more nonce edge cases to handle, the performance tradeoff is worth it. Engine v2 employs multiple patterns and workers to track and self-heal nonces.

We feel confident Engine v2 handles the throughput needs of the vast majority of web3 use cases today.

The next challenge is to improve observability and debuggability around queues and transactions. We plan to expose API metrics, queue latency metrics, realtime nonce details, transaction logs, and more. Our roadmap also includes options to replay failed transactions, reset nonces, and more.

Keep your eyes peeled on the Engine dashboard for updates as we roll them out!

The small team at thirdweb is on a mission to build the most intuitive and complete web3 platform. Our products empower over 70,000 developers each month including Shopify, AWS, Coinbase, Rarible, Animoca Brands, and InfiniGods.

See our open roles. We’d love to work with you!

Unity SDK upgrades can be daunting - this is one of the things v5 solves by moving the core to our .NET SDK - making feature upgrades seamless requiring only a couple file changes at most.

However, for existing v4 users, it can be challenging to integrate a major update, even though it is an objectively better SDK and brings a myriad of improvements and flexibility to the game dev journey.

A migration guide has been added to the portal here.

We've also migrated our Take Flight template and recorded it in realtime to serve as reference.

We have recently refactored our Modular Contracts to introduce new changes that we believe will benefit both the developer and ecosystem experience as a whole.

With that, we have made changes to our Minting, Royalty, Metadata, and a new Sequential Token ID module along with our Core contracts.

In the Claimable and Mintable modules, the beforeMint function has now been split into two functions: beforeMint and beforeMintWithSignature.

All signature-based mints will now be done through the beforeMintWithSignature function, and all regular mints will now be done through the beforeMint function.

With the splitting of functionality, a division in the parameters passed into both functions has also been introduced.

For regular minting, the following parameters are now introduced:

/**
 *  @notice The parameters sent to the `beforeMintERC20` callback function.
 */
struct ClaimParamsERC721 {
	address currency;
	uint256 pricePerUnit;
	bytes32[] recipientAllowlistProof;
}
 
// No params needed for the mintable module

For signature mints, the following parameters are now introduced:

/**
 *  @notice The request struct signed by an authorized party to mint tokens.
 *
 *  @param startTimestamp The timestamp at which the minting request is valid.
 *  @param endTimestamp The timestamp at which the minting request expires.
 *  @param currency The address of the currency used to pay for the minted tokens.
 *  @param pricePerUnit The price per unit of the minted tokens.
 *  @param uid A unique identifier for the minting request.
 */
struct ClaimSignatureParamsERC721 {
	uint48 startTimestamp;
	uint48 endTimestamp;
	address currency;
	uint256 maxMintPerWallet;
	uint256 pricePerUnit;
	bytes32 uid;
}
 
/**
 *  @notice The request struct signed by an authorized party to mint tokens.
 *
 *  @param startTimestamp The timestamp at which the minting request is valid.
 *  @param endTimestamp The timestamp at which the minting request expires.
 *  @param currency The address of the currency used to pay for the minted tokens.
 *  @param pricePerUnit The price per unit of the minted tokens.
 *  @param uid A unique identifier for the minting request.
 */
struct MintSignatureParamsERC721 {
	uint48 startTimestamp;
	uint48 endTimestamp;
	address currency;
	uint256 pricePerUnit;
	bytes32 uid;
}

Reference to code:
ClaimableERC721.sol#L196

In the Claimable module, maxMintPerWallet has now been introduced in both the claimCondition and claimSignatureParams, along with a totalMinted mapping that tracks the number of mints a wallet has done so far.

This change introduces a new validity rule that allows users to set the maximum number of mints a single wallet can make.

Reference to code:
ClaimableERC721.sol#L75

Modular contracts should be composable, and for that to be the case, the functionality of modules should be independent of each other.

We believed that the Mintable module did not achieve this, as it was capable of both validating the mint and setting the URI Metadata.

Due to this, we have removed the functionality to set the URI Metadata from the Mintable module and placed its responsibility solely on Metadata modules.

The Creator Token Standard by Limit Break has now been implemented into the Royalty modules. This introduces a beforeTransfer hook into each of the royalty modules along with a transferValidator that validates whether a transfer should be done or not, based on the policies set for the collection.

You can learn more about the Creator Token Standard here.

Reference to code:
RoyaltiesERC721.sol

updateMetadata is a new hook that has been introduced, allowing users to set the URI of a token as they mint it.

The purpose of introducing the updateMetadata hook was to allow the URI Metadata of a token to be set during minting, but to place this functionality in the Metadata modules rather than the Mintable module.

Reference to code:
BatchMetadataERC721.sol#L114

These three new functions have been introduced to allow the BatchMetadata module to have delayed reveal functionality through the setBaseURI function.

getBatchId and getBatchRange have also been introduced as helper functions to improve the overall user experience when using the setBaseURI function.

SimpleMetadata and DelayedRevealBatchMetadata have both been deprecated in favor of BatchMetadata.

This change was introduced because:

1. BatchMetadata is more gas-efficient than SimpleMetadata while achieving the same functionality.
2. BatchMetadata can now replicate delayed reveal functionality through setBaseURI.

A new module called the SequentialTokenIdERC1155 module has been introduced, which optionally allows for sequential minting in ERC-1155-based collections.

Along with this module, the updateTokenId hook for ERC-1155 core contracts has also been implemented.

Reference to code:
SequentialTokenIdERC1155.sol

To support the newly introduced hook functions, the ERC-721 Core contract now implements the updateMetadata hook, and the ERC-1155 Core contract now implements both the updateTokenId and updateMetadata hooks.

Both of these functions are placed in the mint and mintWithSignature functions.

As previously mentioned:

• updateTokenId is now responsible for optionally updating the token ID.
• updateMetadata is now responsible for optionally updating the URI of a token.

Reference to code:
ERC1155Base.sol#L212

To properly support the updateMetadata hook, the mint function now accepts the new parameter baseURI, which is passed into the updateMetadata hook.

Reference to code:
ERC1155Base.sol#L205

To support the beforeMintWithSignature function in both the Claimable and Mintable modules, the mintWithSignature function has been introduced, which retrieves the signer of the signature and calls the beforeMintWithSignature function.

Reference to code:
ERC1155Base.sol#L230

Not to be confused with the Base chain, Base contracts serve as the core functionality of both Core and CoreInitializable contracts.

Now, both Core and CoreInitializable contracts inherit from the Base contract. This was done to reduce code duplication and improve maintainability.

Reference to code:
ERC1155Base.sol

To find all the changes made in this refactor, head on over to the GitHub repository.

To start using the contracts today, you can find them on the Explore page of the ThirdWeb Dashboard

We've added the ability to retrieve claim conditions across the ERC20, ERC721, and ERC1155 extensions.

import { getClaimConditions } from "thirdweb/extensions/erc20";
import { getClaimConditions } from "thirdweb/extensions/erc721";
import { getClaimConditions } from "thirdweb/extensions/erc1155";
import { getContract } from "thirdweb";
 
const erc20Contract = getContract({
  chain: defineChain(1),
  client: THIRDWEB_CLIENT,
  address: "0x...",
});
const erc20Conditions = await getClaimConditions({
  contract: erc20Contract,
});
 
const erc721Contract = getContract({
  chain: defineChain(1),
  client: THIRDWEB_CLIENT,
  address: "0x...",
});
const erc721Conditions = await getClaimConditions({
  contract: erc721Contract,
});
 
const erc1155Contract = getContract({
  chain: defineChain(1),
  client: THIRDWEB_CLIENT,
  address: "0x...",
});
const conditions = await getClaimConditions({
  contract: erc1155Contract,
});

• Added resolveImplementation support for MATIC proxy
• Removed unusable single phase claim condition extension

With the release of our .NET SDK v2, the next generation of our Unity SDK is finally out of beta - no more platform specific updates!

This version comes with long-awaited features and various speed, stability and performance improvements.

An ecosystem wallet is your own managed in-app wallet service that allows you to create a branded wallet and login system, and allow any number of partners to spin up in-app wallets. End users that create in-app wallets in your partner applications (either with email, phone number, socials or your own custom authentication) will receive one account and wallet address that they can access across all apps and games in your ecosystem.

Ecosystem Wallets use an enclave backend to handle private keys and signing, remaining non-custodial and secure, while also offloading the otherwise sharded wallet client side cryptographic work to a single http request - the ultimate cross-platform friendly account system.

You may upgrade these Ecosystem Wallets to Smart Wallets as you would any other wallet. The API is extremely similar to our In-App Wallets', and in some places simplified as well due to the streamlined infrastructure that powers it.

We've also reworked our login flows to increase speed and performance across the board, it's time to move on from external wallets (or just link them to our embedded wallets from now on through our Unified Identity system!)

Given how our new SDK is structured, where no chain id is necessarily stored in the sdk or wallet's state, you may interact with any chain at will easily, setting up contracts or low level transactions across multiple chains and using a single wallet to execute them all.

Such functionality is now available seamlessly through our Smart Wallet offering. Simply create a smart wallet on any initial chain, and interact with any contract or send any transaction using another chain id - the smart wallet will automatically switch to that chain!

Do note that if you are overriding the default account factory in your connection parameters, that account factory must be deterministically deployed across the chains you are interacting with.

The ThirdwebTransaction.Create inputs have been simplified, removing redundant chain id parameters.
We've also made it simpler to create low level transactions by adding ThirdwebTransactionInput constructors that take in simpler types, and made zkSync transactions go through the EIP712 transaction flow regardless of whether you use a paymaster or not - this means you can override zkSync specific transaction variables like gas per pubdata and we'll still route your transaction through the 712 flow. If none of this made sense to you, don't worry, these are low level uncommon use cases.

[Utils] Added Utils.GetAddressFromENS and Utils.GetENSFromAddress - more info about ENS here.
[Utils] Added Utils.IsDeployed as a standalone way to check if there is contract code at a specified address.
[AA] CallGasLimit UserOp value now accepts user estimated or manual gas limits as overrides automatically if it's above bundler esimated callGasLimit.
[RPC] Improved response time, batching and caching behavior.

[ThirdwebManager] Added EcosystemWalletOptions as a parameter for when connecting to WalletProvider.EcosystemWallet.
[ThirdwebManager] Added EcosystemWalletModal prefab - similar to InAppWalletModal, will spawn if using ThirdwebManager.ConnectWallet with the respective wallet provider and otp-based authentication // fully customizeable, as are all things thirdweb. You may still opt to use our lower level .NET APIs and create your own flows.
[Extensions] Added Unity-specific extension for the NFT type - NFT.GetNFTSprite will return a Sprite loaded with your NFT's image.

No, really. We're serious.

Now that the core is stable, we want to listen to your feedback, improve on all of it while also continuing to add features and unlock more functionality to help game developers, studios and publishers across the globe integrate the best tech ever created - blockchain tech.

UI Components are next, expect Scene_Playground to be updated as we roll those out - first up, production ready, fully featured Connect.

.NET v2: https://www.nuget.org/packages/Thirdweb/2.0.0

Unity v5: https://github.com/thirdweb-dev/unity-sdk/releases/tag/v5.0.0

The thirdweb SDK now supports Basenames or any other L2 ENS subdomains. To convert any Basename to an address, you can use the existing resolveAddress function.

import {
  resolveAddress,
  BASENAME_RESOLVER_ADDRESS,
} from "thirdweb/extensions/ens";
import { base } from "thirdweb/chains";
 
const address = await resolveAddress({
  client,
  name: "myk.base.eth",
  resolverAddress: BASENAME_RESOLVER_ADDRESS,
  resolverChain: base,
});

You can determine any address's Basename using the new resolveL2Name function.

import {
  resolveL2Name,
  BASENAME_RESOLVER_ADDRESS,
} from "thirdweb/extensions/ens";
import { base } from "thirdweb/chains";
 
const name = await resolveL2Name({
  client,
  address: "0x1234...",
  resolverAddress: BASENAME_RESOLVER_ADDRESS,
  resolverChain: base,
});

• Signature mint UIDs now accept a string
• In-app wallet connection is now hidden in the PayEmbed
• Merkletree proof fix for Drop contracts
• Improved error messages for smart wallet connection failures
• Fixed NFT approval on CreateDirectListingButton

We've added a new template project our collection of almost 300 project templates. You can now quickly get started with a React frontend and Go backend using SIWE. Just like Next.js and Express Auth templates, you'll get a fully working app with SIWE authentication via our connect button. You can use this to build gated backend endpoints without any web2 authentication. Check out the template here, and reach out on our support site with any issues.

We've made a big update on thirdweb Pay that enables crypto or credit card sales for any purchase – on-chain or off-chain.

How does this work?

Let's say you want to sell a hoodie and you want to take payment in Base USDC.

You don't want to limit your customers by their ability to find a way to Base. With thirdweb Pay, anyone can buy with anything in their wallet – crypto or physical:

What happens after your customers send you funds? You'll want a secure way to be notified, and kick off your fulfillment flow. This is where webhooks come in.

Create a webhook on your Pay dashboard to securely receive purchase events. Once your webhook is called, kick off your flow to deliver the goods to your customers. You can sell:

• a real-life hoodie
• an NFT of a hoodie
• your custom game token
• anything in your imagination

If you are selling something on-chain, we strongly recommend using thirdweb Engine for delivery.

Get started with thirdweb Pay today. Visit the Commerce section in the Pay playground to start your implementation - it only takes a few seconds. 🔨

Previously, when querying for user details via the in app wallet backend API, you would get something like:

[
  {
    "userId": "2c7af0c5-798d-446a-9a30-305110c57783",
    "walletAddress": "0x9020d2941ad941ABc1C2890301D8F889e263b0C4",
    "phone": "+1234567890",
    "createdAt": "2024-04-03T16:36:26.379156+00:00",
  }
]

Now it returns something like:

[
  {
    "userId": "2c7af0c5-798d-446a-9a30-305110c57783",
    "walletAddress": "0x9020d2941ad941ABc1C2890301D8F889e263b0C4",
    "phone": "+1234567890",
    "createdAt": "2024-04-03T16:36:26.379156+00:00",
    "linkedAccounts": [
      {
        "type": "cognito",
        "details": {
          "phone": "+12265055474"
        }
      }
    ]
  }
]

Note the addition of the linkedAccounts field.

This adds full support for linked accounts which we introduce a while back.

For more details, check out the updated docs here!

thirdweb Pay now supports any chain built on the Polygon AggLayer.

Allow your users to pay with any cryptocurrency or credit/debit card for transactions or tokens on any chain built on the Polygon stack. If you're building a chain on the Polygon stack, let us know!

We've dramatically lowered fees on thirdweb Pay for credit card transactions.

This change is especially impactful for non-US customers, where fees are now cheaper by 20 to 30%!

Pay allows your users to purchase cryptocurrencies and execute transactions with their credit card or debit card, or with any existing cryptocurrency in their wallet. Visit the docs to get started 🛠️ 🚀.

We're excited to introduce the new Connect Button Playground — a powerful new tool designed to simplify the process of configuring the thirdweb v5 SDK's Connect Button

• Easily Customize Wallets: Choose from 350+ popular wallet providers
• Configure In-app wallet sign options: Allow users to sign in using various methods, including Google, Discord, Farcaster, Telegram, Passkey, email, or phone number.
• Real-Time Configuration: Preview and Adjust the appearance and functionality of your Connect Button in real-time, ensuring it perfectly fits your application’s needs.
• Enhanced UI Customization: Fine-tune modal options, appearance, theme, and colors to match the UI perfectly with your app
• Code Generation: Code is generated for your selected configuration so you can easily copy and paste the code and integrate it in your application in seconds!

Try out the new Connect Button Playground

Thirdweb RPC network is rapidly expanding worldwide, enhancing our ability to deliver a more responsive and reliable experience across all regions. With the introduction of Geo Routing, your requests are now intelligently routed to the closest available node, resulting in faster response times.

By routing requests to the nearest node based on the client’s location, RPC Edge achieves reduced latency and enhances global coverage. For example, in regions like Southeast Asia, we've seen up to a 10x improvement in response times. Requests that previously experienced frequent peaks of up to 2 seconds are now consistently processed in under 200 milliseconds.

We remain committed to continually optimizing RPC Edge to seamlessly power every application built on Thirdweb with the best possible performance, no matter where your users are located.

We've redesigned the Connect UI for a better user profile experience. Each wallet now receives a unique gradient avatar based on the address (unless the wallet has an ENS profile image). We've also updated the modal and wallet switching UX for easier wallet management. No changes are necessary to take advantage of the new UI, just upgrade to v5.48.0 or later.

You can now associate any injected wallet with an existing in-app wallet. This works just like our new Unified Identity with the new wallet authentication strategy. The user will be prompted to sign a standard SIWE message that adds the wallet address to the current account's connected profiles list.

import { inAppWallet, createWallet } from "thirdweb/wallets";
import { mainnet } from "thirdweb/chains";
 
const rabby = createWallet("io.rabby");
const wallet = inAppWallet();
 
const account = await wallet.connect({
  client: MY_CLIENT,
  strategy: "wallet",
  wallet: rabby,
  chain: mainnet,
});

This same functionality is available in the prebuilt Connect UI.

• The Pay modal will now only appear if the user doesn't have enough funds to complete the transaction.
• Fixed conditionally rendered hook error when buying funds with fiat

You may now opt to use our new Account Factories that are built on top of the 0.7.0 ERC-4337 standard release, by passing Constants.ENTRYPOINT_ADDRESS_V07 as your entryPoint parameter in SmartWallet.Create or through the ThirdwebManager's ConnectWallet function. Note that we will continue supporting AA 0.6.0 - so no rush.

Among various other things, this unlocks:

• Improved gas costs when interacting with Smart Wallets due to packed UserOp structs and more changes.
• Improved gas limit estimations and faster simulation.
• Token Paymasters - though not live on 0.7 until a little later, the API has been exposed to pass a TokenPaymaster (enum) when creating a Smart Wallet and choose which ERC20 you want users to pay gas with. This is an alternative to the default gasless flow where you sponsor gas for your users.

We've also added support for Abstract Testnet's native account abstraction (ZkSync-based chain).

The new API for authenticating with your backend through SIWE in a single call looks like this now.

public static async Task<T> Authenticate<T>(
        this IThirdwebWallet wallet,
        string domain,
        BigInteger chainId,
        string authPayloadPath = "/auth/payload",
        string authLoginPath = "/auth/login",
        string authPayloadMethod = "GET",
        string authLoginMethod = "POST",
        bool separatePayloadAndSignatureInBody = false,
        IThirdwebHttpClient httpClientOverride = null
)

We've made it a little more flexible so you can hopefully get rid of any custom authentication code you might have and use this helper instead to unlock backend thirdweb auth with any wallet easily.

We've also fixed an issue with some older variants of Smart Wallet factories which resulted in "Invalid SIgnature" being thrown upon personal signing (and by extension, authenticating).

• Low Level - Added IThirdwebWallet.ExecuteTransaction support for external and smart wallets to execute raw low level transaction input rather than going through ThirdwebTransaction.
• Low Level - Simplified the ThirdwebTransactionInput by adding a constructor with user friendly types.
• Mid Level - Added ThirdwebTransaction.Prepare, allowing you to have a quick way to estimate, simulate and populate a transaction without sending it.
• High Level - Deprecated Utils.FetchThirdwebChainAsync, please use Utils.GetChainMetadata as the former will be removed in a future version.

• Stricter coding standards were implemented, making sure the core won't fail you regardless of which .NET version or platform you're on.
• Improved performance and stability across the board.
• Various minor bugfixes were implemented and a couple properties were renamed to improve DX.

We’ve added an EOA Transaction Simulator to thirdweb’s collection of free tools!

Provide details about the sender wallet and the contract method to call, and see the precise error that would be returned by the contract call. Successfully simulated calls also return the estimated gas settings for the transaction.

Use Cases

• Rapidly test behavior with different function arguments.
• Debug failing contract calls when using the Connect SDK or Engine.
• Test your contract permissions by simulating calls from different wallet addresses.

Try it out, bookmark the page, and let us know what tools you’d like to see next!

We just released v5.46 of the thirdweb SDK which adds react native passkey support for in-app wallets.

This means that you can onboard users with just their fingerprint, giving them a full user profile and wallet with just one tap!

You can integrate this using the prebuilt ConnectButton or ConnectEmbed with just one line of code, but it's also very simple to build your own UI and connect using the typescript API.

Here's an example to connect an in-app wallet with passkey, and sponsor all transactions. With this you can make the blockchain completely invisible.

const wallet = inAppWallet({
  auth: {
    passkeyDomain: "example.com",
  },
  smartAccount: {
    chain: base,
    sponsorGas: true,
  },
});
 
await wallet.connect({
  client,
  strategy: "passkey",
  type: "sign-in",
});

Check out the documentation for more info.

Happy building 🛠️

// The external wallet you want to login with
var anyExternalWallet = await PrivateKeyWallet.Generate(client: Client); 
// USING .NET API
// Create the InAppWallet
var wallet = await InAppWallet.Create(
  client: client, 
  authProvider: AuthProvider.Siwe, 
  siweSigner: anyExternalWallet
);
_ = await siweWallet.LoginWithSiwe(chainId: 1);
// USING UNITY API
// Setup auth with SIWE
var siweOptions = new InAppWalletOptions(

);
// Setup connect options with chain ID
var connectOptions = new WalletOptions(
  provider: WalletProvider.InAppWallet, 
  chainId: 421614, 
  inAppWalletOptions: siweOptions
);
// Login with SIWE!
var siweInAppWallet = await ThirdwebManager.Instance.ConnectWallet(connectOptions);
var address = await siweInAppWallet.GetAddress();

// Your main InAppWallet account, already authenticated and connected
InAppWallet mainInAppWallet = ...
// An InAppWallet with a new auth provider to be linked to the main account, not connected
InAppWallet walletToLink = await InAppWallet.Create(
  client: Client, 
  authProvider: AuthProvider.Telegram
);
// Link Account - .NET API
var linkedAccounts = await mainInAppWallet.LinkAccount(
  walletToLink: walletToLink
);
// Link Account - Unity API
var linkedAccounts = await ThirdwebManager.Instance.LinkAccount(
  mainInAppWallet, 
  walletToLink
);
// You can also fetch linked accounts at any time
List<LinkedAccount> linkedAccounts = await mainInAppWallet.GetLinkedAccounts();

The LinkAccount API requires the parameters you typically use to login with a normal InAppWallet. It will authenticate the new wallet and link it directly to the main wallet. This makes it simple to have multiple identities tied a single evm-compatible account.

• Performance and speed improvements for OTP based login methods.
• Added caching for Utils.FetchThirdwebChainDataAsync.
• Added Utils.IsEip155Enforced to check whether a chain enforces EIP 155.
• Added smarter transaction gas fee defaults based on whether chain supports 1559.
• ThirdwebContract.Read and ThirdwebContract.Write can now take in full or partial method signatures:
  • var name = await contract.Read<string>(method: "name", ...)
    still works.
  • var name = await contract.Read<string>(method: "function name() view returns (string)", ...)
    now also works.
  • var name= await contract.Read<string>(method: "name() view returns (string)", ...)
    now also works.
  • var result = await contract.Write(..., method: "claim(address, uint256, address, uint256, (bytes32[], uint256, uint256, address), bytes)", ...)
    now also works.
  • We still recommend using our awesome extensions for common standards such as contract.DropERC20_Claim to make life easier!
• Added support for ERC20 Paymasters.

We've added multi-authentication to the thirdweb SDK. Anyone can now link their in-app wallets to additional profiles like Google, Discord, Telegram, and more. Like all our features, we offer both a prebuilt UI and headless interface for linking profiles. When a user links their profile to an existing in-app wallet, that profile can then be used to authenticate to that wallet.

Unified identities come builtin to the React Connect modal. You can link a profile while signed into an in-app wallet by clicking "Manage Wallet" then "Linked Profiles".

If you're not using React or you'd like to build your own UI, we've added two functions and a hook to make it as easy as possible.

To link a new profile to a currently connected wallet, use linkProfile.

import { inAppWallet, linkProfile } from "thirdweb/wallets";
 
const wallet = inAppWallet();
 
await wallet.connect({ strategy: "google" });
const profiles = await linkProfile(wallet, { strategy: "discord" });

This will return all currently linked profiles. To get the linked profiles at any time, use getProfiles.

import { inAppWallet, getProfiles } from "thirdweb/wallets";
 
const wallet = inAppWallet();
wallet.connect({ strategy: "google" });
 
const profiles = getProfiles(wallet);

This will return a profiles array similar to below.

[
  {
    type: "google",
    details: {
      email: "user@gmail.com",
    },
  },
  {
    type: "discord",
    details: {
      email: "user@gmail.com",
    },
  },
];

If you're using React, the useProfiles hook fetches profiles for the currently connected wallet and handles caching / revalidation for you.

import { useProfiles } from "thirdweb/react";
 
const { data: profiles } = useProfiles();

We've added an extension for the Split contract. See all the available functions in our documentation.

We've added an extension for the Vote contract. See more in our documentation.

• Fixed wallet auto-connect in the React Native SDK
• Updated the serializeTransaction interface to include a separate input for signature
• Added fallback option to get address in ethers5 contract adapter
• Added Abstract L2, Fractal, and Mode Testnet pre-defined chains
• Fixed issue with "All Wallets" appearing in Pay
• Added enabled prop to useWalletBalance

Thirdweb's Unreal SDK is a Code Plugin for Unreal Engine that enables developers to create thirdweb Private Key Wallets, In-App Wallets and Smart Wallets for their games and applications. The plugin provides a simple API and blueprints to interact with wallets, login with email or socials as well as create Smart Wallet session keys.

This update adds AuthProvider.Discord to the InAppWallet list of default auth methods you can use.

var wallet = await InAppWallet.Create(
  client: client, 
  authprovider: AuthProvider.Discord
);

It also comes with a new and improvement OAuth flow that streamlines the experience across all target platforms and includes speed improvements.

We've also updated the Godot integration example to showcase additional OAuth methods.

We're excited to announce the public beta for Engine v2 with a redesigned worker architecture that dramatically increases transaction processing capacity by up to 700x.

Nonces are now assigned in parallel to send a batch of transactions from a single backend wallet at once. This update sends dramatically more transactions per block than Engine v1 (see benchmarks below).

Engine v2 introduces multiple mechanisms to recover if the onchain and Engine wallet nonces differ. It also recycles unused nonces instead of immediately cancelling them, reducing gas used during failed transactions.

API calls are more performant to send transactions (< 40ms server latency) or read transaction status (< 10ms server latency). This speedup means increased throughput with fewer server resources.

With these improvements, Engine v2 is able to send significantly more transactions per second.

Here's a benchmark on B3 Sepolia with 2s block times on a single Starter Cloud-Hosted Engine:

• Engine v2 received 1500 transactions in 10s. Nearly all transactions were sent within 2s and filled up a block (700+ tx/sec)!
• Engine v1 received 250 transactions in 7.7s. Two transactions sent per block (1 tx/sec).

Note: Your results may differ based on chain, transaction type, and sustained load. Some chains and RPC providers may impose additional throughput limits.

• Scale your dApp without worrying about infrastructure limitations.
• Handle traffic spikes and sustained high-volume transactions.
• Optimize gas usage to reduce operational costs.
• Build new use cases that require high-scale transactions.
• Avoid managing nonce synchronization and RPC errors in your backend.

• Cloud-hosted Engine
  • Contact support@thirdweb.com to be upgraded.
  • Developers will be able to upgrade to v2 from the dashboard soon.
• Self-Hosted
  • Pull the latest v2.0.0-beta-rc* image from Docker Hub.

Please share any feedback or contact support for technical issues with Engine v2. We are continuing to test Engine v2 internally and encourage developers to treat Engine as pre-release software.

There are no breaking changes to existing documented interfaces to APIs or webhooks. Pending queued transactions will continue to be processed after the upgrade.

The team is continuing to test Engine on internal production environments.

Engine v2 will be released to the stable release channel after more bugfixes and incorporating customer feedback.

Stay tuned for a technical deep dive on our throughput breakthrough. Your feedback is invaluable as we refine Engine!

thirdweb Engine is an open-source server for your app to read, write, and deploy contracts at production scale.

• [Native] Added support for Discord Login.
• [Cross-Platform] Added support for new chains.

Discord has been added to Prefab_ConnectWallet and can be tested in Scene_Prefabs

Discord login also utilizes a brand new internal flow that should allow you to login faster than you otherwise would with different providers.

As of version 5.44.0, the thirdweb SDK supports Telegram with in-app wallets! Use Telegram like any other auth method.

import { inAppWallet } from "thirdweb";
 
const wallet = inAppWallet();
 
await wallet.connect({
  strategy: "telegram",
});

The CreateDirectListingButton makes it easy to list an NFT on your thirdweb Marketplace contract. Pair it with the BuyDirectListingButton and you can build an entire Marketplace UI in seconds.

import { CreateDirectListingButton } from "thirdweb/react";
 
<CreateDirectListingButton
  contractAddress="0x..." // contract address for the marketplace-v3
  chain={...} // the chain which the marketplace contract is deployed on
 
  // These props below are the same props for `createListing`
  // to get the full list, check the docs link above
  tokenId={0n}
  assetContractAddress="0x..." // The NFT contract address whose NFT(s) you want to sell
  pricePerToken={"0.1"} // sell for 0.1 <native token>
>
  Sell NFT
</CreateDirectListingButton>

We've added more language options to our built-in Connect UI localization. Just specify the language identifier on whatever component you're using.

import { ConnectEmbed } from "react";
 
<ConnectEmbed client={client} locale="ja_JP" />;

• Fixed an issue with ethers5adapter transaction result nonces
• Improved error messages when connection management hooks are used outside ThirdwebProvider
• Fixed autoConnect for wallets that are connected from the "All wallets" screen
• Temporarily disabled login via the CLI
• Fixed an issue with OTP validation in React Native Connect UI
• Added Handling for gas free chains where baseFeePerGas is 0
• Fixed occasional iFrame error when logging in with OAuth

This update comes with a couple additions and changes that should make your developer experience slightly better.

Added SmartWallet.GetAllAdmins and SmartWallet.GetAllActiveSigners helper functions, to respectively get all the admins that might have been added using SmartWallet.AddAdmin and all the temporary signers that were added using SmartWallet.CreateSessionKey and are still unexpired.

GetAllAdmins returns a List<string> of all your admins.

GetAllActiveSigners returns permissions similar to the inputs of CreateSessionKey

SignerPermissions
{
    string Signer // the signer address
    List<string> ApprovedTargets // contracts signer is allowed to interact with
    BigInteger NativeTokenLimitPerTransaction // wei
    BigInteger StartTimestamp // unix
    BigInteger EndTimestamp // unix
}

Furthermore, these functions now throw when called directly on the Smart Wallet, to make sure signatures are 1271 compatible and not confuse developers by forwarding these calls down to the personal wallet acting as a signer.

Functions: SmartWallet.EthSign, SmartWallet.RecoverAddressFromEthSign and SmartWallet.PersonalSign(byte[])

As we begun implementing the .NET SDK on different platforms, we ran into an issue when integrating external wallet types on such platforms - EIP-712.

We've added a utility to remedy this: Utils.ToJsonExternalWalletFriendly<TMessage, TDomain>(TypedData typedData, TMessage message)

This method will convert any typed data parameters into correct and verifiable formats, specially in cases of EIP-1271 Smart Wallet type signatures. If you're implementing an external wallet, we recommend using this util in your IThirdwebWallet.SignTypedDataV4<TMessage,TDomain> overrides.

This has been confirmed to work with MetaMask (native and extension) and WalletConnect.

Thirdweb.Pay specific constants have been removed.

Previously, adding using Thirdweb and using Thirdweb.Pay made it annoying to accesss Thirdweb.Constants - this is no longer the case.

• [WebGL] Added support for Coinbase Smart Wallets
  • Simply use the existing WalletProvider.Coinbase in WebGL to test it out!
  • If you do not have a Coinbase wallet browser extension, you will be prompted to create a Coinbase Smart Wallet.
  • Note that to test this locally you must add a CORS header, see our WebGL Build Instructions for example code.
• [WebGL] Updated bridge.
• [Cross-Platform] Added support for new chains.

Release: https://github.com/thirdweb-dev/unity-sdk/releases/tag/v4.18.0

This patch introduces the ability to call static ThirdwebContract methods as extensions.

For instance ThirdwebContract.Read, ThirdwebContract.Write and ThirdwebContract.Prepare can now be used directly on the ThirdwebContract object.

// Previously
var contract = await ThirdwebContract.Create(...);
var result = await ThirdwebContract.Read<string>(contract, ...);
// In 1.0.2
var contract = await ThirdwebContract.Create(...);
var result = await contract.Read<string>(...);
// Note, both patterns are supported, no migration required

Furthermore, the IThirdwebWallet interface now supports Disconnect directly, so you no longer have to cast to InAppWallet to explicitly call disconnect and clear your local sessions.

Finally, SmartWallet.GetPersonalAccount is now SmartWallet.GetPersonalWallet - this function is used as a simple way to access the IThirdwebWallet acting as the signer for your smart account.

We are excited to announce a significant update designed to bring greater transparency and control to your managed engine instances. At the heart of this update is a suite of new features aimed at giving you deeper insights into the performance and health of your engine instances.

Starting today, you will be able to see the load on your engine instance broken down by status code. This granular view allows you to understand how your traffic is distributed across different types of responses. Whether it’s a successful request or an error, you can now pinpoint exactly where traffic spikes happen. This information is crucial for optimizing performance and ensuring that your services are running smoothly.

In addition to load monitoring, you can now track the error rate over time. This feature provides a historical view of how errors are occurring within your instance. By analyzing error trends, you can identify patterns and potential issues before they become critical. This proactive approach helps maintain a high level of service reliability and reduces downtime.

Finally, we’ve introduced a comprehensive health check feature. This tool gives you a real-time snapshot of your instance’s health. health checks help you stay informed about any potential problems and allow for timely interventions to keep your instances running at peak performance.

We've kicked off a total overhaul of our v5 documentation. In the coming weeks, we'll continue to add content to make building with thirdweb easier than ever. Check out the TypeScript, React, and React Native docs and let us know your thoughts!

We're continuing to add prebuilt components to our Connect UI to make building fully functional apps easier than ever. Today we released the BuyDirectListingButton to buy any token listed via our Marketplace V3 contract.

import { BuyDirectListingButton } from "thirdweb/react";
 
<BuyDirectListingButton
  contractAddress="0x..." // contract address of the marketplace v3
  chain={...} // the chain which the marketplace contract is deployed on
  client={...} // thirdweb client
  listingId={100n} // the listingId or the item you want to buy
  quantity={1n} // optional - see the docs to learn more
>
  Buy NFT
</BuyDirectListingButton>

We've added the useChainMetadata hook to the React SDK to fetch metadata for any chain including name, icon, available faucets, block explorers, and more.

import { useChainMetadata } from "thirdweb/react";
 
const { data: chainMetadata } = useChainMetadata(
  defineChain(11155111),
);
 
console.log("Name:", chainMetadata.name); // Sepolia
console.log("Faucets:", chainMetadata.faucets); // ["https://thirdweb.com/sepolia/faucet"]
console.log("Explorers:", chainMetadata.explorers); // ["https://sepolia.etherscan.io/"]

• Fixed the Connect UI modal when using more than 4 in-app wallet social auth options
• Fixed a bug with passkey, email, and phone number in-app wallet login
• Added ERC20 approval handling in the ClaimButton
• Added the parseAbiParams utility function

We've added Farcaster as an authentication option for in-app wallets. Use the same syntax you'd use for Google, Facebook, Apple, or Discord login.

To connect via farcaster with your own UI:

import { inAppWallet } from "thirdweb/wallets";
 
const wallet = inAppWallet();
 
await wallet.connect({
  strategy: "farcaster",
  client: CLIENT,
});

To connect using the Connect UI components in React or React Native:

import { inAppWallet } from "thirdweb/wallets";
import { ConnectButton } from "thirdweb/react";
 
<ConnectButton
  wallets={[
    inAppWallet({
      auth: {
        options: ["farcaster", "google", "discord"],
      },
    }),
  ]}
/>;

Or, try Farcaster login in our playground.

• Improved tab styling on the Connect UI "View Assets" page
• Significant performance improvements for wallet connection management
• Added the getApprovalForTransaction extension
