Simple Lottery Smart Contract

🚀 Project Overview

The Simple Lottery Smart Contract is a basic decentralized lottery system built on Solidity. Users can enter the lottery, and a random winner is selected on-chain. This contract is deployed on Edu Chain.

📌 Features

✅ Decentralized Lottery: Users can participate in the lottery through blockchain transactions.✅ Random Winner Selection: The contract selects a winner randomly from the list of participants.✅ On-Chain Storage: Players and winners are recorded on the blockchain for transparency.✅ Public Access: Anyone can check the participant count and view the winner's address.

📝 Smart Contract Code // SPDX-License-Identifier: MIT pragma solidity ^0.8.0;

contract SimpleLottery { address[] public players; // Stores player addresses address public winner; // Stores the selected winner

// Function to enter the lottery
function enterLottery() public {
    players.push(msg.sender); // Add sender to the list of players
}

// Function to randomly pick a winner (only for demo, not truly random)
function pickWinner() public {
    require(players.length > 0, "No players joined"); // Ensure at least one player
    uint256 index = uint256(block.timestamp) % players.length; // Pseudo-random selection
    winner = players[index]; // Assign the winner
}

// Function to get total number of players
function getPlayerCount() public view returns (uint256) {
    return players.length;
}

}

🛠️ How to Use

1️⃣ Enter the Lottery: Call enterLottery() to participate.2️⃣ Check Participants: Use getPlayerCount() to see how many people joined.3️⃣ Pick a Winner: Call pickWinner() to randomly select a winner.4️⃣ View Winner: The winner variable will store the selected winner’s address.

⚠️ Disclaimer

This contract uses block.timestamp for randomness, which is not cryptographically secure.

For a secure lottery, consider using Chainlink VRF or an oracle-based random number generator.
