eth_getTransactionCount | BNB Chain

BNB API method that returns the number of transactions sent from an address at the selected block. This value is also called nonce; it is an important piece of information, especially to ensure that a transaction is not sent twice.

Parameters

• address— the address to retrieve the transaction count.

• 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 an instance of severe propagation latency.

  • finalized — the block accepted as canonical by more than 2/3 of the validators. A chain reorganization is extremely unlikely, and it would require at least 1/3 of the staked ETH to be burned.

  • earliest — the earliest available or genesis block.

  • pending — the pending state and transactions block. The current state of transactions that have been broadcast to the network but have not yet been included in a block.

Response

• quantity — an integer value identifying the number of transactions sent from an address at the specified block.

eth_getTransactionCount code examples

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

async function getTransactionsCount(address, blockId) {
  const count = await web3.eth.getTransactionCount(address, blockId)
  console.log(count);
}

getTransactionsCount("0x2D4C407BBe49438ED859fe965b140dcF1aaB71a9", 'latest')

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

const getNonce = async (address, blockId) => {
    const nonce = await provider.send("eth_getTransactionCount", [address, blockId]);
    console.log(nonce);
  };

  getNonce("0x2D4C407BBe49438ED859fe965b140dcF1aaB71a9", "latest")

from web3 import Web3  
node_url = "CHAINSTACK_NODE_URL" 

web3 = Web3(Web3.HTTPProvider(node_url)) 
print(web3.eth.get_transaction_count("0x2D4C407BBe49438ED859fe965b140dcF1aaB71a9", "latest")) 

Use case

One of the most common use cases for eth_getTransactionCountis to create the transaction object built in a script designed to send a transaction. The nonce field is required, and it is retrieved using the eth_getTransactionCount method.
