Beside prefixed with kai_, we also support every eth_ prefixed method so every Web3 library that works with Ethereum will also work with KardiaChain. Some popular library:

  • Web3JS:

  • EthersJS:

  • Web3 py:

  • Web3 dart:

To use web3 library with KardiaChain, simple init with our and use the instance. For example in web3js:

const Web3 = require("web3");
const web3 = new Web3("https://rpc.kardiachain.io");

For more information about the supported eth_ method, please refer to .
