Project Description

In this project, we’ll build and deploy a simple bank application onto a blockchain. We’ll use our smart contract compiled using Solidity and Brownie.

We’ll use Flask to connect the contract with our front end, which is built using React. We’ll use GET requests to connect our application.

The image below shows the final layout of the application, which will be hosted locally.
