Coin Tracker

This app helps user to track desired tokes and get notified when some price is reached. With the power of 1inch API you can add tokens from any chain to the watchlist, set a desired price and the app would ask for datas from 10 to 10 seconds and check if the condition is matched, if yes you'll get notified via telegram.

I've started with Scaffold ETH 2.0 at first, but since there were a lot of unwated request to a localhost server that was supposed to be a chain running a faucet, I tought would be better to go from scratch so I go for Next.js. Here I tried to fetch datas from the 1inch API straightforward but due to a CORS error that saying 1inch api don't accept request from that origin I was struggled to create also an express backend server that would help me to do the requests. Was a lot of fun and many things to learn about web3 Apps.
