Solana Lottery Smart Contract

Overview

This project is a Solana-based lottery smart contract implemented using the Anchor framework. The contract allows participants to buy tickets, draw a winner randomly, and distribute the prize pool securely and transparently on the Solana blockchain.

Features

• Users can buy tickets by sending SOL to the contract.
• The contract tracks ticket ownership.
• An authorized operator can trigger a random draw.
• The winner receives the entire prize pool.
• Transparent and tamper-proof process leveraging Solana's security.

How It Works

1. Ticket Purchase: Participants send SOL to purchase one or more tickets.
2. Draw Winner: At a designated time, an authorized account triggers the draw.
3. Select Random Winner: The contract selects a winner using a randomness source (or pseudorandomness).
4. Prize Distribution: The winner automatically receives the accumulated SOL.
