Smart Contract Setup with Hardhat

To interact with the blockchain and deploy the smart contract, follow these steps:

1. Install Hardhat and the required dependencies:

   cd Contract
   npm install -D hardhat @nomicfoundation/hardhat-toolbox

2. Set up your environment variables by creating a .env file in the root of the project with the following content:

   API_KEY=your_sepolia_rpc_url
   PRIVATE_KEY=your_private_key

   Replace your_sepolia_rpc_url with your own Sepolia network URL (e.g., from Infura or Alchemy), and your_private_key with the private key of your Sepolia account.

3. Here's the hardhat.config.js file you'll be using:

   require("@nomicfoundation/hardhat-toolbox");
   
   /** @type import('hardhat/config').HardhatUserConfig */
   module.exports = {
     solidity: "0.8.28",
     networks: {
       localhost: {
         url: "http://127.0.0.1:8545/",
       },
       sepolia: {
         url: process.env.SEPOLIA_URL,
         accounts: [process.env.PRIVATE_KEY],
       },
     },
   };

Notes

• Replace YOUR_ALCHEMY_API_KEY with your actual Alchemy API key for the Sepolia network.
• Ensure the .env file is added to your .gitignore to avoid exposing sensitive information like private keys.
