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();
