🌳 Polygon — Best Refi Project

Project Description

The project combines the power of mobile wallets with wallet connect integrations. It consist of two front ends. One the previously mentioned easy to use mobile wallet where we used Metamask, Zerion and Slope Wallet as inspiration and the other front end is the recycling machine where it simulates the beer glass bottle collecting and then rewards the user in MATIC after process is done.

How it's Made

We used a Wallet Connect Dart package to create our wallet backend to connect with our Flutter mobile wallet. The recycling machine and wallet both work in the Polygon Mumbai Testnet where it has a smart that triggers a transfer between a wallet that holds all user MATIC rewards after they're done recycling to the the users wallet.

In the backend framework we used node+express js also made use of the web3.js which at first we were really lost at it but got the hang of it. Finally we used an Infura provider on the Polygon Mumbai Tesnet to automatically send transactions to the testnet nodes.
