Simple Raffle Contract

This project demonstrates a basic implementation of a raffle contract using Solidity. Users can initiate various raffles and participate by spending a predetermined amount of Ether. A winner is randomly selected after the end of a raffle.

Features

• Create Raffle: Users can create multiple raffles, each with a distinct prize based on the amount of Ether sent during creation.
• Purchase Tickets: Users can participate in a raffle by purchasing tickets with Ether, increasing their chances of winning.
• Select Winner: After the raffle's predefined expiration time, anyone can trigger the raffle to select a winner randomly.
• Payout Prize: The selected winner receives the entire prize after winning the raffle. Raffle's revenue is transferred to its owner.

Getting Started

Install dependencies

npm install

Deployment

Build the contract running:

npm run build

Deploy the contract to your desired network using Hardhat:

npx hardhat ignition deploy ignition/modules/SimpleRaffle.ts --network NETWORK_NAME

Security Considerations

This implementation uses the block timestamp and hash for randomness, which has limitations in terms of security and predictability. Always exercise caution and conduct thorough testing before deploying to a live environment.
