Weekly Prize Pool Smart Contract

📝 Project Description — Weekly Prize Pool Lottery

Weekly Prize Pool is a lightweight Ethereum smart contract designed to gamify savings, participation, or engagement through a recurring, decentralized lottery system. Anyone can enter by sending ETH, and once per week, a randomly selected participant receives the entire prize pool.

This system promotes fair participation and transparency without the need for off-chain infrastructure, using Ethereum’s built-in beacon chain randomness (block.prevrandao) post-merge.

🎯 Key Features

• Open Participation: Anyone can join the pool by sending ETH — no whitelist or access control required.

• Weekly Rounds: The lottery resets every 7 days, enabling recurring engagement without manual tracking.

• On-Chain Randomness: Uses block.prevrandao (introduced post-Paris hard fork) to generate pseudo-random results.

• Trustless Payouts: Winnings are automatically sent to the selected address — no third party or centralized claim process.

• Self-Resetting: After each round, the contract clears all players and starts fresh, ensuring fairness across weeks.

🧠 Why This Project?

We wanted to build something simple, decentralized, and engaging — a contract that:

• Incentivizes participation

• Demonstrates real smart contract mechanics like randomness, time-based access, and ETH transfer

• Has real-world potential as a base layer for community raffles, prize-linked savings, or Web3 engagement rewards.

No dependencies. No oracles. Just Solidity and the Ethereum blockchain.

🚀 Future Enhancements

If developed further, this project could evolve with:

• Chainlink VRF integration for verifiable randomness

• Automated draws using Chainlink Automation or Gelato

• Token-gated entry or NFT-based rewards

• Frontend interface for Web3 user interaction
