Raffle Smart Contract

📖 Overview

This repository serves as a practical demonstration of utilizing the Hardhat framework and Chainlink automation for Ethereum smart contract development. Inspired by the Solidity, Blockchain, and Smart Contract Course – Beginner to Expert Python Tutorial by Patrick Collins from freeCodeCamp, project is structured to provide a hands-on experience in building, compiling, deploying, and testing Solidity smart contracts. It utilizes chainlink automation to randomly select a winner among those users that register into the raffle with 0.1 eth participation fee.

🚀 Getting Started

🔍 Prerequisites

Node.js
NPM (Node Package Manager) or yarn
Hardhat

🛠 Installation
