Execute the Transaction

Now that we have received the quote and given allowance to Router's Reserve Token Handler, it's time to execute the transaction.
import { ethers } from 'ethers'
const main = async () => {
// getting pathfinder response using the code given in Step 1
const pathfinder_response = await fetchPathfinderData(args)
// setting up a signer
const provider = new ethers.providers.JsonRpcProvider("https://polygon-rpc.com", 137);
// use provider.getSigner() method to get a signer if you're using this for a UI
const wallet = new ethers.Wallet("YOUR_PRIVATE_KEY", provider)
// setting the gas price and limit
pathfinder_response.txn.execution.gasPrice = await wallet.provider.getGasPrice()
pathfinder_response.txn.execution.value = ethers.utils.hexlify(ethers.BigNumber.from(pathfinder_response.txn.execution.value))
pathfinder_response.txn.execution.gasLimit = ethers.utils.hexlify(ethers.BigNumber.from(1000000))
// sending the transaction using the data given by the pathfinder
const tx = await wallet.sendTransaction(pathfinder_response.txn.execution)
try {
await tx.wait();
console.log(`Transaction mined successfully: ${tx.hash}`)
catch (error) {
console.log(`Transaction failed with error: ${error}`)
