  • Install contracts package to use in your repository yarn add @onchain-id/solidity
  • Require desired contracts in-code (should you need to deploy them):
    const { contracts: { ERC734, Identity } } = require('@onchain-id/solidity');
  • Require desired interfaces in-code (should you need to interact with deployed contracts):
    const { interfaces: { IERC734, IERC735 } } = require('@onchain-id/solidity');
  • Access contract ABI ERC734.abi and ByteCode ERC734.bytecode.


  • Install dev dependencies npm i
  • Update interfaces and contracts code.
  • Run lint npm run lint
  • Compile code npm run compile


  • Install Ganache or run another blockchain network.

    The contracts WILL NOT WORK without at least version 2 of Ganache!
