TypeChain

TypeChain is a project created by Krzysztof Kaczor and Neufund that is available under the MIT license. TypeChain is a typescript binding and code generator used to create ethereum smart contracts that features static typing and IDE support. TypeChain is integrated with several libraries which include: truffle, Web3.js 1.0, ether.js, and Web3.js 0.20.x; It also works with JSON ABI and Truffle ABI files. Typechain was made to speed up the development time required for the creation of Ethereum smart contracts and make development tests harder to break.
