-This library is specifically designed for [0x integrators](https://0x.org/docs/introduction/introduction-to-0x), and it simplifies the complex task of parsing [0x transactions](https://etherscan.io/address/0xdef1c0ded9bec7f1a1670819833240f027b25eff) into a format that is both user-friendly and easy to understand. One of the challenges in these trades is that they can experience [slippage](https://0x.org/post/what-is-slippage) through [Automated Market Makers](<[AMMs](https://0x.org/post/what-is-an-automated-market-maker-amm)>) (AMMs), making the final swap amounts difficult to predict prior to executing the trade. However, this library overcomes that challenge by accepting a transaction hash as input and parsing the receipt and event logs to accurately identify the final swap amounts. Try the demo [here](https://0x-parser-demo.vercel.app).
