The transaction object returned by methods like createTransferTransaction() provides a full preview of the transaction before it’s executed. This includes key details such as estimated fees, token transfers, and other relevant metadata—allowing you to display clear, actionable information to users before confirmation. For example:
page.tsx
const transaction = await universalAccount.createBuyTransaction({
  token: {
    chainId: CHAIN_ID.BSC_MAINNET,
    address: "0x59264f02D301281f3393e1385c0aEFd446Eb0F00", // PARTI token on BNB Chain
  },
  amountInUSD: "1",
});
The returned transaction object includes metadata such as sender and recipient addresses, tokens used, and estimated fees. Here’s how to extract and display the estimated fees:
page.tsx
import { formatUnits } from "ethers";

const feeQuote = transaction.feeQuotes[0];
const fee = feeQuote.fees.totals;

console.log("Total fee (USD):", `$${formatUnits(fee.feeTokenAmountInUSD, 18)}`);
console.log("Gas fee (USD):", `$${formatUnits(fee.gasFeeTokenAmountInUSD, 18)}`);
console.log("Service fee (USD):", `$${formatUnits(fee.transactionServiceFeeTokenAmountInUSD, 18)}`);
console.log("LP fee (USD):", `$${formatUnits(fee.transactionLPFeeTokenAmountInUSD, 18)}`);
