TypeChain generates only TypeScript typings (d.ts) files, if you're looking for "opinionated", "batteries included" solution check out our new project: eth-sdk. It generates typesafe, ready to use ethers.js wrappers and uses etherscan/sourcify to automatically get ABIs based only on smart contract addresses. Under the hood, eth-sdk relies on TypeChain. Interacting with blockchain in Javascript is a pain. Developers need to remember not only a name of a given smart contract method or event but also it's full signature. This wastes time and might introduce bugs that will be triggered only in runtime. TypeChain solves these problems (as long as you use TypeScript). TypeChain is a code generator - provide ABI file and name of your blockchain access library (ethers/truffle/web3.js) and you will get TypeScript typings compatible with a given library.
Features
- static typing - you will never call not existing method again
- IDE support - works with any IDE supporting Typescript
- extendible - work with many different tools: ethers.js, hardhat, truffle, Web3.js
- You can create your own target
- frictionless - works with simple, JSON ABI files as well as with Truffle/Hardhat artifacts
- You will also need to install a desired target
