Monad API method that returns the number of transactions sent from an address. This is also known as the account nonce, which is used to prevent transaction replay and ensure proper transaction ordering.

When called against a block older than the latest ~128 blocks, this method is treated as an archive request (2 RUs instead of 1 RU). See request units.

eth_getTransactionCount code examples

ethers.js

const { ethers } = require("ethers");

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

async function getTransactionCount() {
  const address = "0xa54F56e8Cfff25b17105d6073aB0f0E7DA087225";
  const nonce = await provider.getTransactionCount(address);
  console.log(`Transaction count: ${nonce}`);
}

getTransactionCount();
