• Prevent Nonce Errors - Ensure correct transaction ordering
• Track Account Activity - Count transactions sent
• Manage Batch Transactions - Sequential nonce management
• Recover Stuck Transactions - Replace transactions with same nonce

Parameters

1. Address - DATA, 20 Bytes

   • Address to get transaction count for

2. Block Parameter - QUANTITY|TAG

   • latest - Latest block
   • earliest - Genesis block
   • pending - Pending state

Implementation Examples

JavaScript

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY');

// Get nonce for address
const address = '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb8';
const nonce = await provider.getTransactionCount(address);
console.log('Current nonce:', nonce);

// Get pending nonce (includes pending transactions)
const pendingNonce = await provider.getTransactionCount(address, 'pending');
console.log('Pending nonce:', pendingNonce);

Python

from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://api-zetachain-mainnet.n.dwellir.com/YOUR_API_KEY'))

address = '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb8'
nonce = w3.eth.get_transaction_count(address)
print(f'Nonce: {nonce}')
