node_url = "CHAINSTACK_NODE_URL" 

web3 = Web3(Web3.HTTPProvider(node_url)) 
print(web3.eth.get_block_transaction_count("0xbff1ae920dd96597dd486d68b2b7c045c3bdc6d6c64dfeb9759499c9e8ca6737"))

Use case

eth_getBlockTransactionCountByHash is a useful tool for analyzing transaction volume on the Ethereum blockchain. For instance, a new block is generated on the Ethereum blockchain every 12 seconds, resulting in approximately 300 blocks per hour. Using the ethers.js library, one can inspect the past 300 blocks starting from the latest block and use eth_getBlockTransactionCountByHash to find the number of transactions in each block.

index.js

const ethers = require("ethers");

// Create a ChainstackProvider instance for Ethereum mainnet
const provider = new ethers.ChainstackProvider("mainnet");

async function retrieveTransactionsCount() {
    // Get the current block number
    const currentBlockNumber = await provider.getBlockNumber();
  
    // Calculate the block number from one hour ago
    const oneHourAgoBlockNumber = currentBlockNumber - 300; // 300 blocks/hr on average on the Ethereum mainnet
    
    // Initialize a variable to store the total number of transactions
    let totalTransactionCount = 0;
  
    // Loop through all blocks from the current block number to the block number from one hour ago
    for (let block = currentBlockNumber; block > oneHourAgoBlockNumber; block--) {
  
      // Get the hash of each block
      const getBlockHash = await provider.getBlock(block);
      const blockHash = getBlockHash.hash
  
      // Get the number of transactions in this block using each hash
      const transactionCount = await provider.send("eth_getBlockTransactionCountByHash", [blockHash]);
  
      // Add the number of transactions in this block to the total
      totalTransactionCount += Number(transactionCount);
  
      console.log(`Block #${block} has ${Number(transactionCount)} transactions.`);
    }
  
    console.log(`The total number of transactions in the previous hour is: ${totalTransactionCount}`);
  }
  
  
  retrieveTransactionsCount();

This example connects to an Ethereum node using the ethers.js library. The retrieveTransactionsCount function gets the current block number, calculates the block number from one hour ago, and uses a for loop to iterate through all blocks in that range. The function then retrieves the hash of each block and the number of transactions in each block and adds it to a total transaction count. The final result, the total number of transactions in the previous hour, is logged to the console. This is a good example of how you can combine different methods.
