This library is designed for 0x integrators, simplifying the complex task of parsing 0x transactions into a format that is both user-friendly and easy to understand. When swapping tokens, one of the challenges is that the trade can experience slippage through Automated Market Makers (AMMs). This makes the final swap amounts difficult to predict prior to executing the trade. However, this library overcomes that challenge by parsing the transaction receipt and event logs to accurately identify the final swap amounts.
Try out the parser in a live code environment directly in your browser 🌐. You can also experience it in action through the demo UI app, which is built with 0x-parser.
First, make sure you have the required peer dependency viem installed. If you haven't installed it yet, you can do so with the following command:
npm install viem
After installing the peer dependency, proceed to install the @0x/0x-parser package:
npm install @0x/0x-parser
import { parseSwap } from "@0x/0x-parser";
async function main() {
const response = await fetch(
"https://raw.githubusercontent.com/0xProject/protocol/development/packages/contract-artifacts/artifacts/IZeroEx.json"
);
const data = await response.json();
const exchangeProxyAbi = data.compilerOutput.abi;
// You can pass any transaction hash from 0x Exchange Proxy:
// https://etherscan.io/address/0xdef1c0ded9bec7f1a1670819833240f027b25eff
const transactionHash = "0xd8637124d650268ae7680781809800e103a3a2bee9fec56083028fea6d98140b";
const swap = await parseSwap({
transactionHash,
exchangeProxyAbi,
rpcUrl: "https://eth.llamarpc.com",
});
console.log(swap); // Logs the swap details in the console.
}
main();
