eth_getBlockTransactionCountByHash code examples

const { Web3 } = require("web3");
const NODE_URL = "CHAINSTACK_NODE_URL";
const web3 = new Web3(NODE_URL);

async function getTransactionsCount(blockHash) {
  const count = await web3.eth.getBlockTransactionCount(blockHash)
  console.log(count);
}

getTransactionsCount('0xe1af269d0e3f556bb30f61abb4dc00a678c283bd31e18c87f7f16fde8357ce99')

​
Use case

eth_getBlockTransactionCountByHash is a useful tool for analyzing transaction volume on the Aurora blockchain. On average, a new block is generated on the Aurora mainnet every 1.3 seconds, resulting in approximately 2769 blocks per hour. Using a Web3 library, one can inspect the past 2769 blocks starting from the latest block, retrieve the hash of each block, and use eth_getBlockTransactionCountByHash to find the number of transactions in each block.
