  • 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. A chain reorganization is to be expected.
    • safe—the block that received justification from the beacon chain. Although this block could be involved in a chain reorganization, it would necessitate either a coordinated attack by the majority of validators or severe propagation latency.
    • finalized—the block accepted as canonical by more than 2/3 of the validators. A chain reorganization is extremely unlikely, requiring burning at least 1/3 of the staked amount.
    • 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.


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

eth_getBlockTransactionCountByNumber code examples

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

async function getTransactionsCount(blockId) {
  const count = await web3.eth.getBlockTransactionCount(blockId)

const ethers = require('ethers');
const provider = new ethers.JsonRpcProvider(NODE_URL);

const getTransactionsCount = async (blockId) => {
    const count = await provider.send("eth_getBlockTransactionCountByNumber", [blockId]);

from web3 import Web3  

web3 = Web3(Web3.HTTPProvider(node_url)) 
print (web3.eth.get_block_transaction_count(13754975)) # A hex value starting with "0x" is accepted as well.

Use case

eth_getBlockTransactionCountByNumber can be used to analyze how many transactions are included on the Cronos blockchain in a certain period. For instance, on average, a new block is generated on the Cronos mainnet every 5 seconds, resulting in approximately 720 blocks per hour. Using a Web3 library, one can inspect the past 720 blocks starting from the latest block and use eth_getBlockTransactionCountByNumber to find the number of transactions in each block to sum them.
