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

const sendTransaction = async () => {
    const wallet = new ethers.Wallet("YOUR_PRIVATE_KEY", provider);

    const tx = {
      to: "0xRecipientAddress",
      value: 0, // Tempo uses TIP-20 tokens for value transfer
      data: "0x..." // TIP-20 transfer calldata
    };

    console.log(`Transaction hash: ${txResponse.hash}`);
