## `eth_getBlockTransactionCountByHash` code examples

<CodeGroup>
  ```javascript web3.js theme={"system"}
  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('0x0004358a000018587faea5158124f479fb25360d25029e662d336e3a3508ffb3')
  ```

  ```javascript ethers.js theme={"system"}
  const ethers = require('ethers');
  const NODE_URL = "CHAINSTACK_NODE_URL";
  const provider = new ethers.JsonRpcProvider(NODE_URL);

  const getTransactionsCount = async (blockHash) => {
      const count = await provider.send("eth_getBlockTransactionCountByHash", [blockHash]);
      console.log(count);
     };

     getTransactionsCount('0x0004358a000018587faea5158124f479fb25360d25029e662d336e3a3508ffb3');
  ```

  ```python web3.py theme={"system"}
  from web3 import Web3  
  node_url = "CHAINSTACK_NODE_URL" 

  web3 = Web3(Web3.HTTPProvider(node_url)) 
  print(web3.eth.get_block_transaction_count("0x0004358a000018587faea5158124f479fb25360d25029e662d336e3a3508ffb3"))
  ```

## Use case

`eth_getBlockTransactionCountByHash` is a useful tool for analyzing transaction volume on the Fantom blockchain. On average, a new block is generated on the Fantom mainnet every 3 seconds, resulting in approximately 1,200 blocks per hour. Using a Web3 library, one can inspect the past 1,200 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.
