In this project I implemented an App using solidity to develop a smart contract and a simple frontend app in react. The main goal was to create a raffle and transact the money using Ethereum test network Ropstein.
FIrst you will need a cripto wallet. I used MetaMask. After this you need to deploy your smart contract and get it's address, for this I used the Remix IDE. After copying the contract address you need to paste it at the src/index.js in the contractAddress variable.
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
