✨✨ Tutorial: How to Buy a Token on the 🦄 Uniswap Universal Router 🦄 with 🐍 Python 🐍 | HackerNoon ✨✨

Creating a swap transaction for the latest Uniswap router is not as straightforward as it used to be with the previous routers: you cannot just use the router ABI and invoke a swap function.

This guide will teach you how to use Python to build the transaction input data you need to send to the Uniswap Universal Router (UR) in order to buy a token with ETH.

I have developed some time ago an open source Python codec for the UR.Since then I have been asked to clarify some points about its usage. So I decided to write this tutorial.

I would love to hear any constructive feedback about both the Uniswap Universal Router codec and this tutorial, so feel free to comment about them!

Thanks in advance! :)
