Executes a new message call immediately without creating a transaction on the block chain.



  1. Object - The transaction call object

  • from: DATA, 20 Bytes - (optional) The address the transaction is sent from.

  • to: DATA, 20 Bytes - The address the transaction is directed to.

  • gas: QUANTITY - (optional) Integer of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.

  • gasPrice: QUANTITY - (optional) Integer of the gasPrice used for each paid gas

  • value: QUANTITY - (optional) Integer of the value sent with this transaction

  • data: DATA - (optional) Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI in the Solidity documentation(opens in a new tab)↗

  1. QUANTITY|TAG - integer block number, or the string "latest", "earliest" or "pending", see the default block parameter


DATA - the return value of executed contract.


NOTE: In this example we are using public Ethereum endpoint. Ideally, for your own projects, you should use your own endpoint, which you can generate for free by connecting to your wallet here.



  • 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

provider.send('eth_call', [
      "from": null,
      "to": "0x6b175474e89094c44da98b954eedeac495271d0f",
      "data": "0x70a08231000000000000000000000000657CDcB4A6d39B1287da5B0b68f437Cd1E1086D3"
