About
thirdweb is a full-stack Web3 development platform that provides the tooling layer for teams building on-chain applications, games, and commerce experiences. Its smart contract framework includes a library of audited, pre-built contracts for common use cases — ERC-20 tokens, NFT collections, marketplaces, staking, and governance — which developers can deploy to any EVM chain directly from a dashboard without writing custom Solidity. For teams that do write custom contracts, thirdweb's CLI and SDKs handle ABI generation, type-safety, and frontend integration automatically, shortening the feedback loop between contract development and frontend consumption.
