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 PATH_FINDER_API_URL = "https://k8-testnet-pf.routerchain.dev/api"

const getTransaction = async (params, quoteData) => {
    const endpoint = "v2/transaction"
    const txDataUrl = `${PATH_FINDER_API_URL}/${endpoint}`

    console.log(txDataUrl)

    try {
        const res = await axios.post(txDataUrl, {
            ...quoteData,
            senderAddress: "<sender-address>",
            receiverAddress: "<receiver-address>",
            refundAddress: "<refundAddress>" // (optional) By default equal to `senderAddress` if not provided
        })
        return res.data;
    } catch (e) {
        console.error(`Fetching tx data from pathfinder: ${e}`)
    }    
}
    
const main = async () => {
    
    // setting up a signer
    const provider = new ethers.providers.JsonRpcProvider("https://rpc.ankr.com/polygon_mumbai", 80001);
    // 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)
    
    // get transaction data via Transaction endpoint
    const txResponse = await getTransaction(quoteData); // quoteData has been fetched in step 1

    // sending the transaction using the data given by the pathfinder
    const tx = await wallet.sendTransaction(txResponse.txn)
    try {
        await tx.wait();
        console.log(`Transaction mined successfully: ${tx.hash}`)
    }
    catch (error) {
        console.log(`Transaction failed with error: ${error}`)
    }
}

main()
