Many thanks to PeterTheOne for developing initial version at EthPrague.
is a plugin that extends web3.js with additional methods to interact with common token interfaces (ERC20, ERC721, ERC1155...)
Uses @openzeppelin/contracts as a source of contract abi files and does contract type inference like https://github.com/web3/web3-contract-types-example.
Run npm install web3 @chainsafe/web3-plugin-tokens.
import { Web3 } from 'web3';
import { TokensPlugin } from '@chainsafe/web3-plugin-tokens';
const web3 = new Web3('https://eth.public-rpc.com'); // put any node url that is connected to mainnet
web3.registerPlugin(new TokensPlugin());
const daiAddress = '0x6b175474e89094c44da98b954eedeac495271d0f';
const vitalikEth = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045';
const erc20Contract = await web3.tokens.erc20(daiAddress);
const balance = await erc20Contract.methods.balanceOf(vitalikEth).call();
console.log(balance);Run npm run test.
Add them to artifacts.json and run npm run gen.
Then update the tokens-plugin.ts.
