zkevm_batchNumber | zkEVM

Polygon zkEVM API method that returns the current batch number of the chain.

The Polygon zkEVM uses batch verification to improve scalability and reduce gas fees. This means that multiple transactions are grouped together and verified as a single batch using zero-knowledge proofs. The zkevm_batchNumber method returns the current batch number of the zkEVM, which is used to identify the latest batch of transactions being verified.

Parameters

  • none

Response

  • result β€” the latest batch number of the Polygon zkEVM chain, encoded as hexadecimal. The batch number is updated every time a new batch of transactions is added to the chain.

  });

async function batchNumber() {
  const output = await web3.zkEVM.batchNumber()
  console.log(output)
}

const ethers = require('ethers');
const NODE_URL = "YOUR_CHAINSTACK_ENDPOINT";
const provider = new ethers.JsonRpcProvider(NODE_URL);

const batchNumber = async () => {

    // This will return the value in Hex
    const batchNumber = await provider.send("zkevm_batchNumber");
    console.log(`Batch Number: ${batchNumber}`);
  };
