eth_getBlockTransactionCountByNumber | zkEVM

Polygon zkEVM method that returns the number of transactions in a block specified by block number or tag. This information can be useful for analytics purposes.

​

Parameters

• 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. This is the current state of transactions that have been broadcast to the network but have not yet been included in a block.

​

Response

• quantity — an integer value representing how many transactions are included in the block.

eth_getBlockTransactionCountByNumber code examples

const { Web3 } = require("web3");

const NODE_URL = "CHAINSTACK_NODE_URL";

const web3 = new Web3(NODE_URL);


async function getTransactionsCount(blockId) {

  const count = await web3.eth.getBlockTransactionCount(blockId)

  console.log(count);

}


getTransactionsCount('latest')

Use case

eth_getBlockTransactionCountByNumber can be used to analyze how many transactions are included on the Polygon zkEVM blockchain in a certain period. For instance, on average, a new block is generated on the zkEVM mainnet every 3 seconds, resulting in approximately 1,200 blocks per hour. Using a Web3 library, one can inspect the past 1,00 blocks starting from the latest block and use eth_getBlockTransactionCountByNumber to find the number of transactions in each block to sum them.
