Query

NOTE:

• ethers used below is a well-known web3 library, check it out here.

• in the example below we are requesting a DAI ERC20 token balance for address 0x657CDcB4A6d39B1287da5B0b68f437Cd1E1086D3

import { ethers } from 'ethers';

const provider =
  new ethers
    .providers
    .JsonRpcProvider("https://www.noderpc.xyz/rpc-mainnet/public")

provider.send('eth_call', [
    {
      "from": null,
      "to": "0x6b175474e89094c44da98b954eedeac495271d0f",
      "data": "0x70a08231000000000000000000000000657CDcB4A6d39B1287da5B0b68f437Cd1E1086D3"
    },
    "latest"
]).then((result) => {
  console.log(result);
});

Result

0x0000000000000000000000000000000000000000000000000000000000000000
