Executes a new message call immediately without creating a transaction on the block chain. Often used for executing read-only smart contract functions, ofr example the balanceOf for an ERC-20 contract. API Reference


  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. REQUIRED

  • 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)β†—

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


DATA - the return value of executed contract.
