​
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.
See the default block parameter.

​
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.
