Polygon zkEVM API method that enables instant execution of a new message call without requiring the creation of a transaction on the blockchain. This can be useful for testing and debugging by simulating transfers or smart contract transactions and retrieving data from the blockchain.

DisclaimerThe interactive example in this page uses eth_call to call the totalSupply() method from the WETH smart contract on Polygon zkEVM. You can use the Chainstack EVM Knife to convert the result.

​
Parameters

  • object — the transaction call object:
    • from — (optional) the address string used to send the transaction.
    • to — the string of the address to which the transaction is directed, a wallet, or a smart contract.
    • gas — (optional) the maximum amount of gas that can be used by the transaction.
    • gasprice — (optional) the amount of gas price the sender is willing to pay for each gas unit in Wei.
    • value — (optional) the value sent with this transaction, encoded as hexadecimal.
    • data — (optional) additional data to be sent with the call, usually used to invoke functions from smart contracts as a string of the hash of the method signature and encoded parameters. See the Ethereum Contract ABI.
  • quantity or tag — the integer of a block encoded as hexadecimal or the string with:
    • latest — the most recent block in the blockchain and the current state of the blockchain at the most recent block
    • earliest — the earliest available or genesis block
    • pending — the pending state and transactions block. The current state of transactions that have been broadcast to the network but have not yet been included in a block.
See the default block parameter.

​
Response

  • data — the result of executing the specified call on the Ethereum Virtual Machine (EVM), encoded as a hexadecimal string.

eth_call code examples

The following code snippets demonstrate how to simulate a standard ether transfer between two accounts. Note that when using eth_call to simulate a transfer or a smart contract transaction, the sender account must have a sufficient balance to cover the associated gas fee. 
const { Web3 } = require('web3');
const NODE_URL = "CHAINSTACK_NODE_URL";
const web3 = new Web3(NODE_URL);

async function simulateTransfer() {
    try {
        // Define the accounts to transfer between
        const fromAddress = "0x3eb6347f6282E78F778C23c97E8657F5EE5378E0";
        const toAddress = "0x19e7e376e7c213b7e7e7e46cc70a5dd086daff2a";

        // Define the value to transfer (converted to Wei)
        const value = web3.utils.toWei("100", "ether");

        // Build transaction object
        const transactionObject = {
            from: fromAddress,
            to: toAddress,
            gas: 21000, // 21000 is the standard for a regular tranfer
            value: value,
            data: ""
        }

        // Use eth_call to simulate the transfer on the latest block
        const result = await web3.eth.call({
            transactionObject
        }, "latest");

        console.log(`Transaction hash: ${result}`);
    } catch (error) {
        console.error(`Error: ${error.message}`);
    }
}

simulateTransfer();
Executing this code will produce a return value of 0x, indicating a successful transaction. This implies that the transaction will be executed without errors when the code is used to send the transaction.

​
Use case

A common use case for eth_call is calling smart contract functions. For example, interact with an ERC-20 token smart contract deployed on the zlEVM network and retrieve the balance of a specific account.
