## About Hardhat

Hardhat is a development environment designed for Ethereum smart contract developers. It provides tools for compiling, testing, debugging, and deploying smart contracts. This repository demonstrates how to use Hardhat effectively, including:

- Writing and testing Solidity contracts.
- Deploying contracts using Hardhat Ignition.
- Configuring networks for deployment (e.g., Sepolia testnet).

## Getting Started

### Prerequisites

Ensure you have the following installed:

- [Node.js](https://nodejs.org/) (v16 or later)
- [npm](https://www.npmjs.com/) or [yarn](https://yarnpkg.com/)
- [Hardhat](https://hardhat.org/)

### Setup

1. Navigate to the `intro_to_hardhat` directory:
   ```bash
   cd intro_to_hardhat

2. Install dependencies:

   npm install
   

3. Create a .env file in the intro_to_hardhat directory with the following variables, for safe keeping. These keys will actually be added to hardhat configuration:

   ETHERSCAN_API_KEY=your_etherscan_api_key
   SEPOLIA_PRIVATE_KEY=your_sepolia_private_key
   SEPOLIA_RPC=https://sepolia.infura.io/v3/your_project_id
   

Key Features

• Sample Contracts: Includes Lock.sol and Token.sol for learning and experimentation.
• Testing: Demonstrates how to write tests using Hardhat's testing utilities.
• Deployment: Automates contract deployment with Hardhat Ignition.
• TypeScript Support: Provides type-safe contract interactions using TypeChain.

Usage

Compile Contracts

To compile the smart contracts, run:

npx hardhat compile

Run Tests

To execute the tests, run:

npx hardhat test

Deploy Contracts

To deploy contracts using Hardhat Ignition, run:
