A comprehensive platform offering SDKs, audited smart contracts, and developer tools to build web3 apps across Ethereum and 700+ EVM-compatible chains.

thirdweb is a developer-focused platform designed to simplify building decentralized applications (dapps) on Ethereum and over 700 EVM-compatible blockchains. It provides a suite of audited smart contracts, powerful SDKs, and developer tools that streamline the creation, deployment, and management of web3 apps. The platform supports multiple programming environments including TypeScript, React, .NET, Unity, and Unreal Engine, enabling developers to integrate blockchain functionality into a wide range of applications.
The core of thirdweb’s offering is its SDKs and pre-built smart contracts that cover common web3 use cases such as NFTs, token management, wallets, payments, and bridging assets across chains. Developers can quickly bootstrap projects using templates and the thirdweb CLI, then customize contracts and UI components. The platform also includes backend APIs, transaction monitoring, and non-custodial key management services to support robust dapp infrastructure.
What sets thirdweb apart is its extensive chain support (700+ EVM chains), audited contract library, and multi-language SDKs that reduce the complexity of blockchain development. It integrates advanced features like blockchain data insights, onchain payments, and bridging, all accessible through a unified API. The platform’s active community, comprehensive documentation, and open-source examples facilitate rapid onboarding and iteration.
Developers can get started by creating a project with thirdweb’s CLI, setting environment variables, and deploying apps to IPFS. The platform’s React hooks and UI components simplify frontend integration, while backend APIs enable server-side blockchain interactions. thirdweb’s modular architecture supports both frontend and backend workflows, making it suitable for NFT marketplaces, DeFi protocols, DAO tooling, and tokenized platforms.
Building decentralized applications across multiple EVM-compatible blockchains involves complex smart contract development, integration challenges, and managing cross-chain asset flows. Developers face difficulties in deploying secure, audited contracts and maintaining consistent APIs for wallets, payments, and bridging.
