How to use it

// yarn add @tatumio/tatum

import { TatumSDK, Klaytn, Network } from '@tatumio/tatum'

const tatum = await TatumSDK.init<Klaytn>({network: Network.KLAYTN})

const response = await tatum.rpc.getBlockTransactionCountByNumber('0x80F8C7A')

await tatum.destroy() // Destroy Tatum SDK - needed for stopping background jobs


The klay_getBlockTransactionCountByNumber JSON-RPC method allows you to retrieve the number of transactions in a specified block. This method is particularly useful when you need to analyze the transaction activity of a specific block. You can use it to gain insights into network usage, analyze the impact of specific events on the network, or monitor transaction congestion in certain blocks.


  1. blockNumber: The block number for which the transaction count should be retrieved. It should be a hex-encoded value representing the block number.

    • Example: 371156

Return Object

The return object is a hex-encoded value representing the number of transactions in the specified block.

  • Example: "0x1" (1 transactions)
