New bridge contracts have been deployed at 0x7d34a477e2678c8e19d821eec103d4def4af6f4a on select chains.

The Nebula first party app - nebula.thirdweb.com - will be deprecated September 30th 2025 in favor of thirdweb AI. If you have any funds in the nebula in-app wallet - please withdraw them by September 30th 2025. To continue using the service, head over to the thirdweb dashboard

At thirdweb, our mission is to help builders succeed — from those starting their first project to teams scaling to millions of users. To keep improving, we’ve added a new feedback and rating feature in support in dashboard after ticket closure. How it works 1. Go to your thirdweb dashboard,

New Bridge utilities now available as part of the thirdweb API.

Multi-standard support: fetch owners of any token type using one API.

Every project in the thirdweb dashboard now comes with a dedicated AI chat. Think of it as your dev companion in your web3 building journey. What thirdweb AI can do for you * Transact with your connected dashboard wallet * Swap tokens with your connected dashboard wallet * Deploy contracts with rich metadata

For a while, we offered Payments as an all-in-one solution. It helped developers handle everything from accepting crypto payments to moving tokens across chains. But as we grew, we noticed the needs for a crypto checkout and a crypto bridge becoming distinct amongst users. That’s why we’re breaking

As part of ongoing efforts to streamline and maintain our API, we are deprecating several Insight Service endpoints that have seen limited usage. The following endpoints will be deprecated: * GET /v1/transactions/{contractAddress}/{signature} * GET /v1/tokens/transfers/transaction/{transaction_hash} * GET /v1/contracts/deployed-by/{address} * GET /v1/contracts/metadata/

You can now specify custom slippage tolerance on the /bridge/swap endpoint. With the slippageToleranceBps parameter, you can specify how many basis points in slippage your swap can tolerate. Warning: Lower slippage tolerance values could result in reverted swaps. Without this value specified, it will continue to use the default

Wallet Tokens API Enhancement

thirdweb API v1.6

New package: @thirdweb-dev/ai-sdk-provider - A thin provider that lets you plug thirdweb AI into the Vercel AI SDK. It standardizes message parts, exposes wallet-aware tools (sign_transaction, sign_swap), and ships with types/utilities so you can build chat UIs that execute on-chain actions from AI responses. If you’

Expanding our repertoire of authentication providers across all interfaces.

We’ve introduced Auto Execution to the /ai/chat endpoint. When enabled, the AI will not only prepare transactions, swaps, or deployments — it will automatically execute them on behalf of the authenticated user or server wallet. This dramatically reduces friction: no extra signing steps, no manual execution flows. Just describe

New GET /v1/auth/social endpoint for simplified OAuth - replaces deprecated OAuth in /v1/auth/initiate

Earlier this week we launched the ability to deploy your own token right from the dashboard, complete with a liquidity pool and developer rewards. Today, we're releasing this same capability via the thirdweb API. You can now programmatically: * Launch your token on a decentralized exchange * Set up a

Launching an ERC20 token is now faster, easier, and more rewarding. Your community can start buying, trading, and holding from day one — while you earn fees in the background! The new ERC20 token creation flow, you can: * Launch your token on a decentralized exchange * Set up a Uniswap V3 pool

It is easier than ever to get users started with blockchain interactions.

Overview This guide helps you migrate from the legacy Nebula API (nebula-api.thirdweb.com/chat) to the new thirdweb AI Chat API (api.thirdweb.com/ai/chat). Quick Reference First API Field Second API Field Notes message messages[].content Single string → Array of message objects session_id context.session_id

We’ve added an OpenAI-compatible AI Chat endpoint specialized for blockchain interactions, powered by thirdweb’s 't0' model. It can query live on-chain data, analyze transactions, prepare contract calls, swaps, and more via a single /ai/chat call. Docs: https://portal.thirdweb.com/ai/chat Playground: https://playground.

Adding thirdweb Payments to our flagship HTTP API.

Stargate routes are now included in thirdweb Payments.

Meet the thirdweb API: A Revolutionary Unified Interface for Web3 Development.

Arbitrum Stylus brings a second, WebAssembly (WASM) virtual machine to every Arbitrum chain, so you can write contracts in Rust (or C/C++) while staying 100 % interoperable with existing Solidity code. Under the hood, Stylus executes WASM thousands of times faster than the EVM, so transactions are metered in a
