Lottery Smart Contract Project

This project is a Lottery Smart Contract implemented using Solidity and Hardhat. It uses block timestamp/difficulty as a source of randomness.

Project Structure

The project is structured as follows:

• contracts/: Contains the Solidity contracts for the Lottery.
• scripts/: Contains the deployment scripts for the contracts.
• test/: Contains the test scripts for the contracts.
• deploy/: Contains the deployment configuration for the contracts.
• hardhat.config.ts: Contains the configuration for Hardhat.
• package.json: Contains the project dependencies and scripts.

Prerequisites

Before you begin, ensure you have met the following requirements:

• You have installed Node.js and npm.
• You have a local Ethereum blockchain such as Hardhat Network or Ganache.
• You have an Alchemy API key and a private key for an Ethereum account.

Setting Up

1. Clone the repository to your local machine

2. Install the project dependencies by running

npm install

3. Create a .env file in the root directory of the project and add your Alchemy API key and private key

PRIVATE_KEY="your-private-key"
ALCHEMY_API_KEY="your-alchemy-api-key"

Deploying the Lottery Contract Locally

1. Start your local node

npx hardhat node --no-deploy

2. Deploy the Lottery contract to your local node (Open another terminal)

npx hardhat deploy --network localhost --tags Lottery

Testing the Lottery Contract Locally

1. Run the tests for the Lottery contract

npx hardhat test --network localhost test/01_lotteryTest.ts

Deploying the Lottery Contract to a Live Network

1. Deploy the Lottery contract to a live network

npx hardhat deploy --network <blockchain-network> --tags Lottery

Note: Please replace <blockchain-network> with the name of the Ethereum network you want to deploy to.
