Ever wondered if your token is supported on Universal Bridge? You can check all routes for a given token using the routes page. Search by chain ID, token address, token symbol, or name for all origin and destination routes. You can access the site at thirdweb.com/routes.

You can use the transactions array returned by a Universal Bridge prepared quote to easily execute a full route from origin to destination. This pattern is now even easier with transaction action fields included to denote what each transaction does. The most important of these actions is the approval type, which represents a pre-assembled approval transaction. The approval will account for the sender's existing set allowance and what token is needed for the next step.

A quote response might look something like this:

    }
  ],
}

To execute this bridge with the TypeScript SDK, use sendAndConfirmTransaction to send each transaction, and wait for a successful Bridge.status response for each non-approval transaction:

import { Bridge, sendAndConfirmTransaction } from "thirdweb";
 
for (const tx of preparedBuy.transactions) {
  const hash = await sendAndConfirmTransaction({
    transaction: prepareTransaction(tx),
    account, // Learn to generate a thirdweb account https://portal.thirdweb.com/connect/wallet/get-started
  });
 
  if (tx.action !== "approval") {
    // Wait for Bridge.status to return "COMPLETED" status
  }
}

It's that easy to implement bridging and swapping in your app. Want to get started? You can find the full API reference here.

Insight now supports webhooks so you can build pipelines and receive notifications when specific blockchain events or transactions occur!

With the introduction of webhook support in Insight, you can now seamlessly integrate blockchain data into your applications or workflows. Webhooks allow you to automatically receive near real-time notifications whenever specific blockchain events or transactions occur, eliminating the need for constant polling of the blockchain.

• Automate Workflows: Trigger actions in your applications or services when a specific blockchain event happens (e.g., a token transfer, contract interaction, or wallet activity).
• Monitor Blockchain Events: Stay updated on relevant events without manually querying the blockchain.
• Build Custom Pipelines: Use webhooks to feed blockchain data into analytics tools, databases, or other systems for further processing.
• Filter Specific Data: Configure webhooks to only receive notifications for events or transactions that meet your specific criteria, such as a particular contract address or event type.

Yes! Insight webhooks provide decoded data for events and transactions. This means you’ll receive human-readable payloads that include all relevant details, such as parameters and values associated with the event or transaction. This makes it easier to process and use the data directly in your applications without additional decoding steps.
To enable this, you have to define specific event signatures / function signatures and partial ABIs in the webhook filter configurations.

We’ve released the Agglayer Module, designed to enable secure and seamless cross-chain transfers of ERC-20 tokens using Agglayer, an interoperability protocol. Learn more about Agglayer.

Please note: This module is currently in beta while the Agglayer bridge is not live in implementation. This means deployments are limited to Sepolia and Cardona as it requires Ethereum as an L1 and zkEVM as L2.

The Agglayer Module is a module contract that can be added to any ERC-20 modular contract built with thirdweb’s modular framework. It allows developers to bridge ERC-20 tokens across any EVM-compatible chain.

As the Ethereum ecosystem continues to grow with the introduction of more Layer 2 networks, fragmented liquidity and isolated user experiences have become major challenges. Without interoperability, assets are locked within specific chains, limiting usability and adoption.

The Agglayer Module helps address this by enabling interoperability at the contract level—allowing tokens to move freely across chains, reducing fragmentation, and improving the overall developer and user experience.

• EVM-compatible – Works across all EVM chains
• Modular and upgradeable – Can be installed or removed from any ERC-20 modular contract
• Dashboard integration – Easily install through the thirdweb dashboard with no additional configuration
• Cross-chain functionality – Mint tokens and send them to other chains seamlessly

• The module currently only works with ERC-20 modular contracts
• It must be installed on the contract in order to function

1. Use or deploy an ERC-20 modular contract
2. Add the Agglayer Module through the thirdweb dashboard
3. Mint and bridge tokens as needed

Insight added support for querying a wallet's transactions (both inbound and outbound). Previously this had to be two separate queries, but can now be done by a single query.

Try it out in our playground

To fetch a wallet's transactions on Ethereum

const getWalletTransactions = async (walletAddress: string) => {
  try {
    const response = await fetch(
      `https://1.insight.thirdweb.com/v1/wallets/${walletAddress}/transactions`,
      {
        headers: {
          "x-client-id": <THIRDWEB_CLIENT_ID>,
        },
      },
    );
    const res = await response.json();
    return res.data;
  } catch (error) {
    console.error("Error:", error);
  }
};

With v5.93.0 of the TypeScript SDK, we've added full beta functionality for thirdweb's new Universal Bridge. The bridge currently covers 50+ chains and over 30,000 routes.

• Bridge.Buy - Specify an exact destination amount to receive
  • quote: Get estimates without a wallet connection
  • prepare: Get finalized quotes with transaction data
• Bridge.Sell - Specify the exact origin amount to send
  • quote: Get estimates without a wallet connection
  • prepare: Get finalized quotes with transaction data

When you call prepare, you might get multiple transactions back. You must send all transactions in order and sequentially for the full route to succeed. Before sending each transaction, call Bridge.status for the previous transaction until it returns COMPLETED. Do not simply wait for the transaction receipt, as this doesn't account for the destination chain transaction (if there is one).

The transactions returned do not include approvals. Send any necessary approvals before their corresponding transactions.

• Bridge.routes - Advanced function to discover and filter available bridge routes
  • Filter by token address, chain ID, or both
  • Full pagination support with customizable limit and offset
• Bridge.status - Comprehensive transaction status tracking
  • Clear status indicators: "COMPLETED", "PENDING", "FAILED", or "NOT_FOUND"
  • Detailed transaction reporting including origin and destination amounts and chains

• Standardized error handling with descriptive, formatted error messages
• Four underlying types are exported for use with the bridging functions:
  • Route: Defines bridge routes between chains and tokens
  • Status: Represents bridge transaction status data
  • Quote: Contains detailed bridge transaction quote information
  • PreparedQuote: Extends Quote with complete transaction data

The Bridge module is accessible as a top-level export:

import { Bridge } from "thirdweb";

Use Bridge.Buy, Bridge.Sell, Bridge.routes, and Bridge.status to access the corresponding functionality.

Or, import the functions directly from the module:

import { Buy, Sell, routes, status } from "thirdweb/bridge";

We've built Universal Bridge to allow your users to use any asset on any chain, and it's ready for you to try.

This integration simplifies onchain asset trading, and we've added extensions in .NET to integrate with any IThirdwebWallet nicely.

The design is akin to letting us know what your intent is.

• Buy: "I want to buy x USDC on y Chain using z Token"
• Sell: "I want to sell x USDC on y Chain for z Token"
• Transfer: "Just transfer all my money to vitalik"

We will return the transactions needed to achieve whatever you desire.
You may then handle execution yourself or use our extensions.

using Thirdweb.Bridge;
// Create a ThirdwebBridge instance
var bridge = await ThirdwebBridge.Create(client);

var buyQuote = await bridge.Buy_Quote(
    originChainId: 1,
    originTokenAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC on Ethereum
    destinationChainId: 324,
    destinationTokenAddress: Constants.NATIVE_TOKEN_ADDRESS, // ETH on zkSync
    buyAmountWei: BigInteger.Parse("0.1".ToWei())
);
Console.WriteLine($"Buy quote: {JsonConvert.SerializeObject(buyQuote, Formatting.Indented)}");

var preparedBuy = await bridge.Buy_Prepare(
    originChainId: 1,
    originTokenAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC on Ethereum
    destinationChainId: 324,
    destinationTokenAddress: Constants.NATIVE_TOKEN_ADDRESS, // ETH on zkSync
    buyAmountWei: BigInteger.Parse("0.1".ToWei()),
    sender: await Utils.GetAddressFromENS(client, "vitalik.eth"),
    receiver: await myWallet.GetAddress()
);
Console.WriteLine($"Prepared Buy contains {preparedBuy.Transactions.Count} transaction(s)!");

var sellQuote = await bridge.Sell_Quote(
    originChainId: 324,
    originTokenAddress: Constants.NATIVE_TOKEN_ADDRESS, // ETH on zkSync
    destinationChainId: 1,
    destinationTokenAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC on Ethereum
    sellAmountWei: BigInteger.Parse("0.1".ToWei())
);
Console.WriteLine($"Sell quote: {JsonConvert.SerializeObject(sellQuote, Formatting.Indented)}");

var preparedSell = await bridge.Sell_Prepare(
    originChainId: 324,
    originTokenAddress: Constants.NATIVE_TOKEN_ADDRESS, // ETH on zkSync
    destinationChainId: 1,
    destinationTokenAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC on Ethereum
    sellAmountWei: BigInteger.Parse("0.1".ToWei()),
    sender: await Utils.GetAddressFromENS(client, "vitalik.eth"),
    receiver: await myWallet.GetAddress()
);
Console.WriteLine($"Prepared Sell contains {preparedSell.Transactions.Count} transaction(s)!");

Why not just transfer with the SDK? Stay tuned for webhooks, think direct payments!

var preparedTransfer = await bridge.Transfer_Prepare(
    chainId: 137,
    tokenAddress: Constants.NATIVE_TOKEN_ADDRESS, // ETH on zkSync
    transferAmountWei: BigInteger.Parse("0.1".ToWei()),
    sender: await Utils.GetAddressFromENS(client, "vitalik.eth"),
    receiver: await myWallet.GetAddress()
);
Console.WriteLine($"Prepared Transfer: {JsonConvert.SerializeObject(preparedTransfer, Formatting.Indented)}");

This is not production code, we're just showcasing some of the APIs that would help you execute and poll status here.

// You may use our extensions to execute yourself...
var myTx = await preparedTransfer.Transactions[0].ToThirdwebTransaction(myWallet);
var myHash = await ThirdwebTransaction.Send(myTx);
// ...and poll for the status...
var status = await bridge.Status(transactionHash: myHash, chainId: 1);
var isComplete = status.StatusType == StatusType.COMPLETED;
Console.WriteLine($"Status: {JsonConvert.SerializeObject(status, Formatting.Indented)}");
// Or use our Execute extensions directly to handle everything for you!

The SDK comes with some extensions that you'll see on a lot of ThirdwebBridge objects, and the main one is Execute.

// Execute a prepared Buy
var buyResult = await bridge.Execute(myWallet, preparedBuy);
var buyHashes = buyResult.Select(receipt => receipt.TransactionHash).ToList();
Console.WriteLine($"Buy hashes: {JsonConvert.SerializeObject(buyHashes, Formatting.Indented)}");
// Execute a prepared Sell
var sellResult = await bridge.Execute(myWallet, preparedSell);
var sellHashes = sellResult.Select(receipt => receipt.TransactionHash).ToList();
Console.WriteLine($"Sell hashes: {JsonConvert.SerializeObject(sellHashes, Formatting.Indented)}");
// Execute a prepared Transfer
var transferResult = await bridge.Execute(myWallet, preparedTransfer);
var transferHashes = transferResult.Select(receipt => receipt.TransactionHash).ToList();
Console.WriteLine($"Transfer hashes: {JsonConvert.SerializeObject(transferHashes, Formatting.Indented)}");

We've built Universal Bridge to allow your users to use any asset on any chain, and it's ready for you to try. If you're interested in joining the private beta for Universal Bridge, complete this form (or reach out to anyone from the thirdweb team).

Do you need to accept fiat and crypto payments in your app? Are you struggling to find reliable onchain liquidity for swaps? Are you tired of implementing bespoke bridges for multiple chains? Universal Bridge is for you.

Bridging, swapping, and accepting payments each bring their own challenges. The existing options are unreliable, complicated, and reliant on poor design choices. Universal Bridge is the easiest way to route assets in your app. Swap tokens, bridge between chains, onramp assets, accept onchain payments, and more all with a simple, unified API.

We already support 30,000+ routes across 50+ chains and are adding more every day. We're running detailed routing and reliability tests across all of them to guarantee a great experience for users.

Universal Bridge uses a combination of existing protocols and onramps with thirdweb's own onchain and off-chain infrastructure for maximum coverage and reliability. The result is a "best case scenario" for buying, selling, and transferring assets between any EVM chain.

Our Private Beta starts today, and your app can be one of the first to use it. Just complete this form or reach out to anyone on the team to get access. Or, try the playground widget here.

We're excited to announce that thirdweb Insight has expanded its blockchain data querying capabilities to 67 chains, including these 7 new chains:

• Sonic testnet
• Scroll
• Linea
• Zero mainnet
• Zero testnet
• Blast
• Mode

What This Means For Developers
With these additions, you can now use all of Insight's powerful features across these new chains.

Try them out on the playground!

We've revamped our metadata storage and refresh mechanisms to provide a more reliable, scalable, and efficient experience when working with NFT collections metadata through Insight!

• Replaced the previous caching approach with a more permanent storage solution, ensuring faster retrieval and better consistency across requests.
• Metadata is now stored and accessed in a way that eliminates potential inconsistencies, making it the single source of truth for retrieval.

To give developers more control, we’ve introduced dedicated API endpoints for refreshing metadata on demand:

• Collection Metadata Refresh
  • GET v1/nfts/metadata/refresh/:contract_address
• Token Metadata Refresh
  • GET v1/nfts/metadata/refresh/:contract_address/:token_id
• Both endpoints fully support multichain operations via chain query parameters.
• Refreshing token metadata also ensures collection-level metadata stays up to date.

✅ Improved Data Consistency – Eliminates mismatches between different layers, ensuring metadata stays accurate.
✅ Simplified Architecture – No more juggling between temporary and permanent storage solutions.
✅ Better Scalability – Optimized for large-scale metadata operations, enabling more efficient handling of growing datasets.
✅ Multichain-Ready – Works seamlessly across chains, just like you’re used to.

We’re actively working on further performance optimizations by consolidating multiple separate queries into more efficient, single-fetch operations. This will unlock even faster metadata retrieval without sacrificing accuracy. Stay tuned with more updates to thirdweb Insight! 🚀

This new update includes several changes to the tools in thirdweb MCP (Model Context Protocol) Server – improving overall accuracy in tool selection and speed performance for some onchain queries.

Improvement and Fixes

• Improved onchain query performance and tool selection
• Fixed Engine service auth requests that were not configured properly

Happy building! 🛠️

We're excited to announce the first release of thirdweb ai, a powerful Python library (TypeScript coming soon) that enables AI agents to interact with any EVM chains autonomously using thirdweb. This is a significant step forward in our mission to make web3 more accessible and empower developers to build the next generation of AI-powered onchain applications.

As Large Language Models (LLMs) and AI Agents continue to evolve as transformative technologies, we recognized the need for these systems to interact with blockchain networks autonomously. We believe that giving AI agents the ability to perform onchain actions based on real-time data will unlock new possibilities.

With thirdweb ai, you can create AI agents that:

• Manage wallets and transactions securely using Engine
• Retrieve and analyze on-chain data in real-time using Insight
• Delegate complex onchain executions to Nebula agents

All of this functionality integrates smoothly with the AI agent framework of your choice, including OpenAI Agents, LangChain, AgentKit, GOAT, AutoGen, LlamaIndex, and many more.

Install the core package with all adapters:

pip install "thirdweb-ai[all]"

Or choose specific framework adapters:

# For OpenAI Agents
pip install "thirdweb-ai[openai]"
 
# For LangChain
pip install "thirdweb-ai[langchain]"
 
# For AutoGen
pip install "thirdweb-ai[autogen]"
 
# For LlamaIndex
pip install "thirdweb-ai[llama-index]"
 
# For additional frameworks
pip install "thirdweb-ai[goat]"
pip install "thirdweb-ai[agentkit]"
pip install "thirdweb-ai[mcp]"
pip install "thirdweb-ai[smolagents]"
pip install "thirdweb-ai[pydantic-ai]"

See here for the full list of supported framework and installation guides.

We just shipped a big upgrade to partner management for ecosystems. You can now specify what type of signatures are permitted for each partner, as well as granular controls on what exactly can be signed. As an ecosystem owner, this means you have full control of what each partner is able to do with your user's ecosystem wallets, like restricting to particular assets or actions.

In your ecosystem dashboard, you'll find a new option for "Access Control" when you create or edit an ecosystem partner. You can setup these signing restrictions in 2 ways: your own server verification, or built in rules.

This is the most flexible and powerful option - every signature request will flow through your own server and you get to perform your own logic for allowing or disallowing a particular signature.

The response from your sever should just be a simple JSON body with the following format.

{ 
  isAllowed: boolean;
  reason?: string;
}

You can also set your rules directly in the dashboard. These include what signature types you would like to allow, and granular permissions per signature type, like the chain, contract addresses or function selectors that are allowed to be called.

For ecosystems that use smart accounts, since those require personal_sign signatures, we've added a user operation filter that lets you control which smart account operations are allowed to be signed by the ecosystem wallets.

These controls are low level and powerful, letting you tightly control what can and cannot be done with wallets on a per-partner basis.

We're continuously improving this UI to make it easier for ecosystem owners to setup these rules. Your feedback is appreciated and help us make this product better for everyone!

We're excited to announce improvements to our Token and NFT APIs in Insight. We've recently added support to get all token transfers by owner, wallet, and token contracts. We've also included in this release major performance improvements to existing NFT endpoints.

The following endpoints are now available to use.

We’re pleased to announce a more robust contract verification process, now featuring a dedicated Etherscan verification status check and final result reporting. This means you can confidently verify your contracts—proxy or otherwise—knowing you’ll receive a much more clear outcome every time.

Added Verification Status Check and Final Result Return

• Introduced extra logic to check for verification status on Etherscan-like explorers, which polls for verification completion.
  • This now returns the final verification result (e.g., "success," "failure," or "already verified") instead of just the receipt GUID.

Fixed Constructor Parameter Fetching for Proxy Contracts

• Fixed some corner cases where we should use the implementation address when verifying proxied contracts with constructor parameters.

We hope this streamlined verification workflow reduces the friction of contract verifications and helps you focus on delivering great applications. Happy building!

We're excited to announce an important update to our RPC edge infrastructure at thirdweb. This enhancement is designed to improve performance and reduce costs for our users.

• Response Compression at RPC Edge:
  We’ve enabled response compression, meaning our RPC endpoints now deliver compressed responses to reduce data size and speed up transmission.
• Cost Reduction for Users:
  With smaller payloads, users can enjoy reduced bandwidth usage and lower overall costs when interacting with our servers.
• New Request Requirement:
  To take full advantage of this update, you need to add an Accept-Encoding header to your requests. This tells our servers that your client can handle compressed responses.

Simply include the Accept-Encoding header in your API requests. For instance, if you're calling the eth_blockNumbermethod using our RPC endpoint, you can use the following curl example:

curl -H "Content-Type: application/json" \
     -H "Accept-Encoding: gzip" \
     -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
     https://1.rpc.thirdweb.com

In this example:

• The Accept-Encoding: gzip header signals that your client accepts gzip-compressed responses.
• The JSON payload makes a call to eth_blockNumber to retrieve the latest block number.

This update is part of our continuous effort to enhance performance and efficiency. We’re committed to providing you with the best tools and infrastructure for your development needs. If you have any feedback or questions, please don’t hesitate to reach out.

The thirdweb SDK comes with built-in tree-shaking, meaning your application only keeps what it uses from the SDK. However, we still like to keep the overall package size as small as possible for convenience while you're running your application in development. With version 5.92.0 we've reduced the package install size by more than 25%, from 199 MB to 144 MB. See the latest here.

Unfortunately, this means we've had to remove support for 3D models in the media renderer. You can still display 3D model NFTs in your application using our IPFS resolvers and Three.js or a similar library.

We're excited to announce the release of additional NFT API endpoints to Insight. These endpoints provide comprehensive APIs for accessing NFT metadata, transfers, ownership information, and more. The NFT API provides a great alternative for developers looking to migrate from SimpleHash, which is expected to shutdown on March 27th.

The endpoints below are now available to use.

GET https://{chain}.insight.thirdweb.com/v1/nfts/{contract_address}

Querying token prices in USD is now supported by Insight API!

Try it out in our playground

To fetch a token's price by its contract address

(0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee is used for native tokens)

const getPrice = async () => {
  try {
    const response = await fetch(
      "https://1.insight.thirdweb.com/v1/tokens/price?address=0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
      {
        headers: {
          "x-client-id": <THIRDWEB_CLIENT_ID>,
        },
      },
    );
    const priceData = await response.json();
    return priceData.data;
  } catch (error) {
    console.error("Error:", error);
  }
};

Response

[
  {
    chain_id: 1,
    address: '0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee',
    symbol: 'ETH',
    price_usd: 2192.917084798869,
    price_usd_cents: 219291
  }
]

You can optionally define a timestamp and the API will return the closest data it has to that timestamp.

const getPrice = async () => {
  try {
    const ts = Date.now() - 3 * 60 * 60 * 1000; // 3 hours ago
    const response = await fetch(
      `https://1.insight.thirdweb.com/v1/tokens/price?address=0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee&timestamp=${ts}`,
      {
        headers: {
          "x-client-id": <THIRDWEB_CLIENT_ID>,
        },
      },
    );
    const priceData = await response.json();
    return priceData.data;
  } catch (error) {
    console.error("Error:", error);
  }
};

To fetch token prices by symbol

const getPriceBySymbol = async () => {
  try {
    const response = await fetch(
      "https://1.insight.thirdweb.com/v1/tokens/price?symbol=ETH",
      {
        headers: {
          "x-client-id": <THIRDWEB_CLIENT_ID>,
        },
      },
    );
    const priceData = await response.json();
    return priceData.data;
  } catch (error) {
    console.error("Error:", error);
  }
};

Note that there can be multiple tokens with the same symbol

We support more than 6000 tokens currently and keep adding more.

We also provide an endpoint to fetch the list of supported tokens for each chain.

We’re excited to share that Thirdweb now better aligns with Etherscan’s latest V2 API. If you regularly need to have your contracts verified on Etherscan-like explorers, this change means a more streamlined, less error-prone experience - so you can spend more time shipping, and less time wrestling with parameters. One click on the Thirdweb dashboard is all it takes!

• V2 API Readiness: Our system automatically targets Etherscan V2 endpoints for the correct chain, minimising manual setup and reducing the possibility of misconfiguration.
• Future-Proofing: This approach lays the groundwork for supporting additional block explorer APIs with minimal friction, ensuring that Thirdweb utilities remains flexible and up-to-date.

The goal behind these changes is to make verifying your smart contracts as hassle-free as possible. By cutting down on repetitive parameters and streamlining the integration with Etherscan V2, we’ve drastically reduced the chance of errors. Ultimately, we want you to focus on the things that matter—innovating, building, and delivering great blockchain experiences.

We’re always improving our developer experience, so if you have any questions or feedback, reach out to us. In the meantime, we hope you enjoy the smoother, more robust contract verification process!

Insight now serves NFT assets through the Thirdweb Gateway, improving retrieval times by caching the content on a globally serving data on edge. Instead of referencing IPFS or Arweave links, insight automatically resolves them to edge-friendly endpoints, so metadata no longer displays IPFS URLs. This deployment works seamlessly with the existing NFT schema without requiring any additional steps. It enhances performance, reduces latency, and ensures consistent, high-speed access to decentralized assets.

Example:

before:

"image_url": "ipfs://QmY1vKaHd3UvbzStxgndUMH3FzprK7jTJcAvgbHbcLsZXv/107.png"

After

"image_url": "https://5c9e93b8acbb5d972c1841911a7dce5f.ipfscdn.io/ipfs/QmY1vKaHd3UvbzStxgndUMH3FzprK7jTJcAvgbHbcLsZXv/107.png"

This means you can use the image directly in your frontend, the snippet bellow would render the NFT image from thirdweb gateway.

  <img src="https://5c9e93b8acbb5d972c1841911a7dce5f.ipfscdn.io/ipfs/QmY1vKaHd3UvbzStxgndUMH3FzprK7jTJcAvgbHbcLsZXv/107.png" alt="NFT Image" />

Effective Date: March 3, 2025, at 3:00 PM PST

Announcing some important changes to our mint fee process that further standardize our fee structure for all new contract deployments. We are introducing a 1% protocol fee applied to all contracts, and adjusting the convenience fee to 1.5% from previous 2.5%.

We believe this change strikes the right balance between a standardized protocol fee and the flexibility for custom fee settings, making fee management easier and more transparent for everyone.

Please note this change does not effect already deployed contracts.

• Fixed protocol fee:
  All new deployments now include a non-overridable 1% protocol fee. This fee is implemented into the contract and will always apply if deployed through SDK, dashboard, or third-party integrations. For example, an asset listed at 0.1 ETH will distribute 0.099 ETH to the seller and 0.001 ETH to the platform.
• Convenience Fee:
  When deploying via dashboard, the fee includes a 1.5% convenience fee or 2.5% total (1% protocol fee plus an additional 1.5%). For example, an asset listed at 0.1 ETH will distribute 0.0975 ETH to the seller and 0.0025 ETH to the platform.
• Custom Fee Configuration:
  You can still set your own platform fee during deployment or later via our platform. The process works exactly as before, with the custom fee now being applied in addition to the fixed thirdweb fee.

This adjustment helps support continued development and maintenance of prebuilt smart contracts, ensuring reliability, security, and innovation for the ecosystem.

For any questions or further details, please reach out to our support team.

• Which prebuilt contracts will have included fees?
  • The following contracts and corresponding modular versions will now include a seller fee:
    • Drop Contracts: DropERC20, DropERC721, DropERC1155, OpenEdition
    • Token Contracts: TokenERC20, TokenERC721, TokenERC1155
    • Specialized Contracts: LoyaltyCard, BurnToClaim, MarketplaceV3
• I deployed a contract prior to the effective date, will these fees apply to me?
  • This fee is only applied to any contracts deployed after 3:00 pm PST on March 3, 2025

We Introduced a new include_spam query parameter to the ERC20 token endpoint to filter out potential spam tokens.

GET /v1/tokens/erc20/vitalik.eth&include_spam=true

The criteria for identifying spam include:

• Empty token name

• Empty token symbol

• Symbol length greater than 15 characters

• Zero decimals

By default, spam tokens are excluded from responses (include_spam=false). You can try it in our playground by visiting here. See the example bellow:

Here is a Typescript example showing how to use it in your code:

fetchTokens = async () => {
  try {
    const response = await fetch(
      "https://1.insight.thirdweb.com/v1/tokens/erc20/vitalik.eth?metadata=true&include_spam=true",
      {
        headers: {
          "x-client-id": clientId,
        },
      },
    );
    const tokensResult = await response.json();
    return tokensResult;
  } catch (error) {
    console.error("Error:", error);
  }
};

We are now supporting NFT metadata for Insight NFT balance endpoints (ERC-721 and ERC-115).

By adding metadata=true query parameter to the request, the response will include metadata about the NFT - name, description, image URL, background color, external URL, collection and contract info in addition to the balance.

Here's an example of the data that can be returned:

The Insights API now supports querying contract metadata and ABIs. Powered by our contract indexing and verification backend, developers can now access verified contract metadata and ABIs for all supported chains directly within Insights. This eliminates the need to interact with block explorers and third party source code verifiers to get contract metadata and ABIs.

We've added the following endpoints:

curl https://insight.thirdweb.com/v1/contracts/abi/0x66a9893cc07d91d95644aedd05d03f95e1dba8af?chain=1&clientId=THIRDWEB_CLIENT_ID

Both endpoints are available in the playground to test.

Stay tuned for more updates and exciting features from Thirdweb!

We’re excited to unveil a powerful addition to the thirdweb platform: a brand-new API designed to automate chain onboarding in real time. This release is especially useful for Rollup-as-a-Service (RaaS) providers, who can now seamlessly integrate new chains into the thirdweb ecosystem the moment they’re spun up. No more back-and-forth or manual listing processes—this API provides a streamlined way to manage your chains on thirdweb.

1. Automated Registration of Newly Spun-Up Chains
   Our new API endpoints let you programmatically add or update chain configurations on the thirdweb platform. This is critical for RaaS providers who rapidly deploy new chains and need an immediate, frictionless connection to thirdweb.
2. Seamless Integration with Existing Workflows
   Because the API is designed for simplicity, it easily slots into your existing DevOps workflow. You can add a single API call to your chain deployment scripts, automatically informing thirdweb about the new chain’s details—no manual steps required.
3. Real-Time Updates
   Once your chain is registered, the thirdweb platform reflects the changes immediately, so developers can start using thirdweb tools (SDKs, CLIs, and dashboards) on your newly created chains right away.
4. Robust Documentation and Tooling
   We’ve launched an accompanying API Reference that covers everything you need—from authenticating requests to building complex integration flows. You’ll find clear examples, success and error response codes, and best practice guidelines.

Below are some of the most commonly used endpoints. A full list of endpoints and usage examples can be found in the API docs.

• POST /chains
  Register a new chain with thirdweb. Supply essential metadata (e.g., chain name, chain ID, explorer URLs, stack type and custom RPC urls) for immediate onboarding.
• GET /chains
  Fetch details about chains added by your team. Useful for verifying that your chains has been successfully added and has all the relevant info present.
• PUT /rpcUrls/{chainId}
  Add RPC urls for an existing chain, very requested by RaaS providers.

• Speedy Deployment: Spin up a new rollup chain and instantly register it with thirdweb in a single automated step.
• Less Overhead: No more waiting on manual reviews or dealing with miscommunications. Your chain data stays in sync whenever you roll out a new version or fork.
• Scalability: Whether you have one chain or a thousand, the API is built to handle bulk provisioning and updates.

1. Review the Documentation
   Check out the API docs for quickstart guides and detailed references.
2. Generate an API Key
   Obtain an API key from your thirdweb dashboard. This key will authenticate your requests.
3. Integrate With Your Deployment Scripts
   Add API calls to your RaaS deployment pipeline or CI/CD workflow to register new chains automatically.
4. Test & Monitor
   Use the provided sandbox environment or your standard staging area to test new chain registrations before rolling out changes to production.

We’re committed to making thirdweb the most developer-friendly platform for emerging blockchain solutions. Here’s a sneak peek at what’s coming next:

• Account Abstraction
  Automate provisioning and integration with your custom account abstraction flows for enhanced security and better user experiences.
• Universal Bridge (previously thirdweb Pay)
  Simplify asset transfers across different chains with an automatically provisioned, interoperable payment/bridge layer.
• Insight
  Gain real-time analytics and diagnostics across all your chains—insightful dashboards and metrics will be automatically enabled for new rollups.

Expect these features—along with additional endpoints, analytics hooks, and security enhancements—to be part of our continued effort to streamline multi-chain support.

Stay tuned for details and in the meantime, don't hesitate reaching out to get early access and needed permissions to be able to utilise this and give us feedback!

As always, thank you for building with thirdweb!

We’re introducing metadata retrieval in our ERC20 token API!

You can now include token information—such as name, symbol, and decimals—in a single call to our /tokens/erc20 endpoint. Just add the new metadata=true parameter to the query string. For example:

GET /v1/tokens/erc20/vitalik.eth&metadata=true

This returns the token’s metadata along with the usual balance data, simplifying your workflows and saving you from making extra calls. We’ve also added caching so metadata lookups are faster after the first request.

You can try it in our playground by visiting here. See the example bellow:

Here is a Typescript example showing how to use it in your code:

const search = async () => {
 try {
   const response = await fetch('https://1.insight.thirdweb.com/v1/tokens/erc20/vitalik.eth?metadata=true', {
      headers: {
        "x-client-id": clientId,
      },
    });
   const tokensResult = await response.json();
   return tokensResult
 } catch (error) {
   console.error('Error:', error);
 }
};

Insight API added support for querying block data.

Try it out on our playground

Or use it directly from code

const getBlock = async (blockNumber: number) => {
  try {
    const response = await fetch(
      `https://1.insight.thirdweb.com/v1/blocks?filter_block_number=${blockNumber}&limit=1`,
      {
        headers: {
          "x-client-id": <your-client-id>,
        },
      },
    );
    const blockResponse = await response.json();
    return blockResponse.data[0];
  } catch (error) {
    console.error("Error:", error);
  }
};

Insight API now supports an explorer-like endpoint to resolve blockchain data.

The resolve endpoint supports

• Transaction hashes - returns the transaction data
• Block hashes - returns the block data
• Addresses (also ENS names)
  • In case of an EOA - returns last 20 transactions from that address
  • In case of a contract - returns last 20 transactions to that address
• Event signatures - returns the latest 20 events with the given signature
• Function signatures - returns the latest 20 transactions with the given signature

Try it out on our playground

Or use it directly from code

const resolve = async () => {
 try {
   const response = await fetch('https://1.insight.thirdweb.com/v1/resolve/0xe01d4a0dbd117152f14c081a8b91b4f55429c469e2dc1530ea00d2714c6bb2a8', {
      headers: {
        "x-client-id": clientId,
      },
    });
   const result = await response.json();
   return result
 } catch (error) {
   console.error('Error:', error);
 }
};

This endpoint was initially called v1/search/:input but was changed to v1/resolve/:input to better reflect its purpose.

At thirdweb, innovation is in our DNA. We’re excited to share a behind-the-scenes look at how our team is continuously pushing the boundaries to deliver an unparalleled user experience. Today, we're diving into some key upgrades that have transformed our RPC server.

We’ve made a bold move by switching our RPC server to the Bun runtime. This isn’t just a technological upgrade—it’s a leap toward efficiency. With this change, we’ve managed to slash memory usage by 30%. What does that mean for you? More network requests are handled seamlessly, ensuring a smoother and more responsive experience without the need for extra hardware.

Performance matters, and every millisecond counts. By introducing short-term caching into our architecture, we’ve dramatically reduced latency. Our metrics tell the story:

• P90 latency is down by 50%.
• P95 latency has improved by a whopping 300%.

These numbers translate into faster response times and a more robust service, even during peak usage periods.

Understanding every nuance of our system is key to delivering excellence. We’ve integrated fine-grained our Performance Monitoring that drills down into every RPC call. This means we now track method-level usage and latency, giving us a crystal-clear view of performance across the board. With this insight, we’re empowered to act swiftly, optimizing our service before issues can arise.

Insight is an extremely useful and performant tool to query blockchain data and can decorate it quite nicely too.

Did you know that vitalik, on Ethereum, Polygon and Arbitrum alone owns 7811 ERC20s, 34,362 ERC721s and 2,818 ERC1155s?
Let's go through some examples!

Instantiation

using Thirdweb.Indexer;
// Create a ThirdwebInsight instance
var insight = await ThirdwebInsight.Create(client);

Simple Args

// Setup some filters
var address = await Utils.GetAddressFromENS(client, "vitalik.eth");
var chains = new BigInteger[] { 1, 137, 42161 };

Fetching all tokens owned by a given address

// Fetch all token types
var tokens = await insight.GetTokens(address, chains);
Console.WriteLine($"ERC20 Count: {tokens.erc20Tokens.Length} | ERC721 Count: {tokens.erc721Tokens.Length} | ERC1155 Count: {tokens.erc1155Tokens.Length}");

Fetching a specific type of token owned by a given address

// Fetch ERC20s only
var erc20Tokens = await insight.GetTokens_ERC20(address, chains);
Console.WriteLine($"ERC20 Tokens: {JsonConvert.SerializeObject(erc20Tokens, Formatting.Indented)}");
// Fetch ERC721s only
var erc721Tokens = await insight.GetTokens_ERC721(address, chains);
Console.WriteLine($"ERC721 Tokens: {JsonConvert.SerializeObject(erc721Tokens, Formatting.Indented)}");
// Fetch ERC1155s only
var erc1155Tokens = await insight.GetTokens_ERC1155(address, chains);
Console.WriteLine($"ERC1155 Tokens: {JsonConvert.SerializeObject(erc1155Tokens, Formatting.Indented)}");

Fetching Events
Note: most of these parameters are optional (and some are not showcased here)

// Fetch events (great amount of optional filters available)
var events = await insight.GetEvents(
    chainIds: new BigInteger[] { 1 }, // ethereum
    contractAddress: "0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d", // bored apes
    eventSignature: "Transfer(address,address,uint256)", // transfer event
    fromTimestamp: Utils.GetUnixTimeStampNow() - 3600, // last hour
    sortBy: SortBy.TransactionIndex, // block number, block timestamp or transaction index
    sortOrder: SortOrder.Desc, // latest first
    limit: 5 // last 5 transfers
);
Console.WriteLine($"Events: {JsonConvert.SerializeObject(events, Formatting.Indented)}");

Engine is one of thirdweb's most important products. We've created an EngineWallet class that can be used as an IThirdwebWallet and as such benefits from being compatible with the entire SDK!

Usage:

// EngineWallet is compatible with IThirdwebWallet and can be used with any SDK method/extension
var engineWallet = await EngineWallet.Create(
    client: client,
    engineUrl: Environment.GetEnvironmentVariable("ENGINE_URL"),
    authToken: Environment.GetEnvironmentVariable("ENGINE_ACCESS_TOKEN"),
    walletAddress: Environment.GetEnvironmentVariable("ENGINE_BACKEND_WALLET_ADDRESS"),
    timeoutSeconds: null, // no timeout
    additionalHeaders: null // can set things like x-account-address if using basic session keys
);
// Simple self transfer
var receipt = await engineWallet.Transfer(chainId: 11155111, toAddress: await engineWallet.GetAddress(), weiAmount: 0);
Console.WriteLine($"Receipt: {receipt}");

Integrated with last December's EIP-7702 release!

• Arbitrum, Arbitrum Nova and Arbitrum Sepolia gas price related methods now get shortcut early and return maxFeePerGas = maxPriorityFeePerGas = current gas price.
• Utils.GetChainMetadata chain id related variables updated from int to BigInteger.

We’ve made significant enhancements to thirdweb Insight, allowing you to efficiently query ERC-20, ERC-721, and ERC-1155 token balances for any address.

We identified latency issues on bigger chains where some requests took over 10 seconds.
Our improved indexing logic has reduced p99 query latency to under 1.5 seconds across all chains.
This is just the first step and we'll keep on improving the performance of Insight

Want to try it out? All endpoints are available on our playground: ERC-20 queries, ERC-721 queries and ERC-1155 queries.

Insight open source indexer has received it's first major version upgrade in beta to 1.0.2-beta and brings with it more scalable reorg handling, better reliability and more performance.

• Token Balances API endpoint - The indexer API now has a new `/balances/:owner/:type` endpoint to retrieve token balances by type (ERC20, ERC721, ERC1155) for a specified address. Added features include aggregation support, customizable responses, and options for pagination and filtering.
• Materialized views for token balances - Created materialized views to keep track of token balances as logs are being inserted.
• Chain based table configuration for Clickhouse - when using Clickhouse as a data store, you can now configure table names and default columns.
• Field selection for storage connectors - Specific fields can be fetched via storage connectors to not query everything and improve performance.

• Improved reorg handling with Clickhouse data store - Migrated database tables to use `VersionedCollapsingMergeTree` for better data accuracy and scale when indexing multiple chains.
  NB! This is a breaking change!
• Added serialization for API responses with specific column selection to better control the data returned. Also replaced array-based topics in logs with fixed columns for more reliable data handling.
• Enhanced committing integrity - added safeguards to track the last committed block, preventing data inconsistencies and duplicate insertion.
• Graceful shutdown - Implemented context cancellation for all orchestrator components to support graceful shutdown, improving application reliability during deployment disruptions.
• GetTraces Consistency - Updated trace fetching logic to conform to API standards and enabling consistent pagination and filtering across the codebase

This update introduces substantial improvements in API functionality and performance, database consistency, and overall reliability. These changes facilitate better integration, data retrieval, and system robustness, especially in cloud-deployed environments.

You can now use thirdweb dashboard to deploy contracts deterministically (create2) on multiple EVM chains.

To use this feature, deploy any thirdweb prebuilt or a custom contract using thirdweb dashboard. Then navigate to the Cross chain tab on contract page as shown below:

Use the dropdown to select the chain you wish to deploy on. Then click on Deploy button.

Once the contract gets deployed (or if it's already deployed at that address), the status will change to Deployed and you can click the link as shown above to navigate to that chain's contract page.

This feature is available for all thirdweb prebuilt contracts as well as custom contracts that are deployed / published using thirdweb tools. All direct deploy contracts (i.e. not proxy) must be deployed deterministically to enable this feature.

Note: this feature is available only for EVM chains

Go ahead and deploy a contract here.

Previously, the thirdweb dashboard only allowed you to import contracts, without the ability to associate them with specific projects. Contracts were displayed as a single list across teams, projects, and account pages.

Now, you can organize your contracts within projects for better management.

As part of this update, all your deployed contracts have been automatically added to all your projects. You can now review each project and keep only the relevant contracts by removing others from the project

When deploying a new contract, you can now add it to a project immediately.

Existing contracts can be added to projects with the new "Add to Project" button on the contract details page. Here's Doodles NFT contract for example:

Unlike the previous "Import to Dashboard" and "Remove from Dashboard" actions, adding or removing contracts from a project no longer requires signing a message.

The Published Contracts page has been removed from the Teams and Projects pages and is now accessible via your Wallet profile page. A Link to the wallet profile page is also added in the Account Management Dropdown as shown below

Here's the thirdweb.eth profile page for example

• Smart Wallet transaction receipt polling can now time out based on your client "Other" timeout options, similar to normal transactions.
• Our dashboard now supports rotating your secret keys. Rotated secret keys are now supported in this version.
• You can now call InAppWallet or EcosystemWallet's Create function and instantly login with a twAuthTokenOverride which would be an auth token/cookie that you would have retrieved from any other thirdweb app, such as a web app, electron launcher, or any app built using our various SDKs.

var forwardedWallet = await InAppWallet.Create(
    client: myClient, 
    authProvider: AuthProvider.Github, 
    twAuthTokenOverride: "my.auth.token"
);

Previously, it was only possible to go from .NET to other React apps using GenerateExternalLoginLink, this unlocks the other way.

Effective Date: February 11, 2025, at 2:00 PM PST

Since launching in 2021, over 2 million smart contracts have been deployed with our toolkit — powering billions of transactions every year. We’re making some changes to our fee structure to better support the development of our smart contract development toolkit.

Starting on the effective date, a 2.5% platform fee (applied to both native and ERC20 tokens) will be introduced for all prebuilt contracts deployed through the thirdweb dashboard after 2 pm PST on February 11, 2025.

Please note this change does not effect already deployed contracts.

This change applies to any contracts that have a primary sale recipient, including but not limited to:

• Drop Contracts: DropERC20, DropERC721, DropERC1155, OpenEdition
• Token Contracts: TokenERC20, TokenERC721, TokenERC1155
• Specialized Contracts: , LoyaltyCard, BurnToClaim, MarketplaceV3

• The 2.5% fee will be automatically deducted from primary sales executed through these contracts. For example, an asset listed at 0.1 ETH will distribute 0.0975 ETH to the seller and 0.0025 ETH to the platform.
• The fee applies only to prebuilt contracts deployed via the thirdweb dashboard. Custom contracts or externally deployed contracts remain unaffected.
• The fee is charged from the primary sale, including a claim or mint action when there is a price on the NFT (non-zero). The fee is paid in the same currency as the claiming or minting price.

This adjustment helps support continued development and maintenance of prebuilt smart contracts, ensuring reliability, security, and innovation for the ecosystem.

For any questions or further details, please reach out to our support team.

• Which prebuilt contracts will have included fees?
  • The following contracts and corresponding modular versions will now include a seller fee:
    • Drop Contracts: DropERC20, DropERC721, DropERC1155, OpenEdition
    • Token Contracts: TokenERC20, TokenERC721, TokenERC1155
    • Specialized Contracts: LoyaltyCard, BurnToClaim, MarketplaceV3
• I deployed a contract prior to the effective date, will these fees apply to me?
  This fee is only applied to any contracts deployed after 2 pm PST on 2/10/2025.
• Can I opt out of the changes?
  • This change only applies to contracts deployed via the dashboard and not any contracts deployed programatically.

This release introduces a powerful credential management system and adds support for Circle's Web3 Services wallets. Circle, known for USDC and trusted by major financial institutions, provides institutional-grade wallets with bank-level security and SOC certifications - perfect for teams that need robust security assurance and regulatory compliance.

Managing cloud credentials across multiple wallets has always been a pain point. We've fixed that with a new credential system that brings enterprise-grade security features to your wallet infrastructure.

What's awesome about it:

• Easy Rotation: Update credentials for multiple wallets at once by rotating their shared credential - perfect for regular security maintenance
• Security at Scale: All wallets using the same credential automatically inherit security updates and policy changes
• Audit Superpowers: Easily track which wallets are using which credentials for security reviews and compliance
• Emergency Ready: Quick response to security incidents by updating credentials across all affected wallets simultaneously

We've added support for Circle's w3s developer-controlled wallets, bringing enterprise-grade signing capabilities to Engine. These wallets integrate seamlessly with our new credential management system and existing Engine infrastructure for transaction management.

Upgrade to engine v2.1.32, then try creating a smart backend wallet backed by Circle:

POST /wallet-credentials
{
  "type": "circle",
  "label": "my-circle-credential",
  "entitySecret": "..."
}

POST /backend-wallet/create
{
    "type": "smart:circle",
    "credentialId": "..."
}

Learn more about the entitySecret and how to create one from the Circle docs.

Take a look at our docs to learn more about configuring Engine to support Circle wallet, and check out our API Reference for detailed documentation and more examples.

We're working on expanding the credential system to support more wallet types and rolling out default credentials. Stay tuned for updates!

We're working on expanding support for more institutional wallet providers. Using Fireblocks, Copper, or another institutional wallet provider? We want to hear from you! Let us know which integrations would help your team ship faster.

Got questions? Join our Discord or check out the documentation.

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.

This update brings natural language support for token swapping and bridging, expanded access to offchain knowledge, and improved session context management.

• Added support for swapping and bridging tokens in natural language
  • Example → "Swap 1 USDC to 1 USDT on the Ethereum Mainnet" or "Bridge 0.5 ETH from Ethereum Mainnet to Polygon"
• Added more support for offchain knowledge including research headlines and articles about tokens or protocols
  • Example → “Tell me more about $UNI project”
• Support for updating context using the /session/{session_id} endpoint
  • Example,

{
  "message": "Hello Nebula!",
  "context": { 
    "session_id": "...",
    "wallet_address": "0x...",
    "chain_ids": ["1", "11155111"]
  },
}
