Back End Lottery Smart Contract

Project Overview

This project serves educational purposes, offering a web application that allows users to place bets on randomly generated numbers using Ether. A smart contract manages the bets, receives Ether, and determines the winning number randomly. The participant with the correct number receives the accumulated Ether sum.

The project is divided into 3 projects:

• Lottery Smart Contract: This handle the bets and decided the winner of the bets. Also reward the winner with all money available;
• Back-end Lottery Smart Contract*: This handle the requests from the user and send it to the smart contract.
• Front-end Lottery Smart Contract: This is the user interface that the use perform actions.
