Thirdweb JS Library
An open-source full-stack web3 development platform offering SDKs, APIs, and prebuilt contracts to build, monetize, and scale blockchain applications across EVM chains and Solana.
Overview
thirdweb is an open-source, full-stack web3 development platform designed to simplify building, monetizing, and scaling decentralized applications. It provides a comprehensive suite of tools including SDKs, APIs, prebuilt smart contracts, and infrastructure services that support all EVM-compatible blockchains and Solana. Developers can deploy and manage tokens, wallets, payments, bridges, and account abstraction features with minimal setup, enabling rapid iteration and production readiness.
The platform offers SDKs for popular programming environments such as TypeScript, React, React Native, Unity, Unreal Engine, and .NET, making it accessible for web, mobile, and gaming developers. Its modular architecture includes components for contract deployment, wallet management, transaction handling, real-time blockchain data querying, and secure key management through a non-custodial vault. thirdweb also integrates AI-powered blockchain models and discoverable APIs with built-in payment mechanisms to support autonomous agent interactions.
What sets thirdweb apart is its extensive ecosystem support, covering every EVM chain plus Solana, combined with audited prebuilt contracts and account abstraction capabilities that simplify gas management and user onboarding. Its flexible pricing tiers scale from small teams to large enterprises, with dedicated infrastructure options and guaranteed support SLAs. Notable integrations include powering multi-sig wallets securing over $100 billion in assets, NFT launches like King of Destiny with rapid sales, and Coinbase’s NFT creation and transaction management. Developers can get started quickly via the open-source SDKs, extensive documentation, and an interactive playground environment.
