🚀 Objective:

• Learn how to connect a frontend application (React) to Ethereum smart contracts using Ethers.js.
• Set up a wallet connection (MetaMask) to allow users to interact with the blockchain.
• Learn how to read and write data on Ethereum through your React app.
• Mint NFTs or interact with a DeFi contract directly from the frontend.

🧠 What is Ethers.js?

Ethers.js is a JavaScript library that allows you to interact with the Ethereum blockchain. It helps developers read data from the blockchain (e.g., checking balances, retrieving smart contract data) and send transactions (e.g., calling contract functions, sending ETH).

🔑 Key Features of Ethers.js:

• Lightweight: Ethers.js is small and easy to use.
• No dependencies: It does not rely on large, complex libraries like Web3.js.
• Wallet support: Ethers.js can connect to MetaMask and other Ethereum wallets.
• Interacts with Smart Contracts: It allows you to interact with contracts on Ethereum, testnets, and Layer 2 solutions.
• Signer and Provider: It has built-in Signer (for signing transactions) and Provider (for reading data from the blockchain) mechanisms.

🏗️ Setting Up Your React App

Step 1: Initialize React App

1. Open your terminal and create a new React project using TypeScript template:

   npx create-react-app my-dapp --template typescript
   cd my-dapp
   
   

Step 2: Install Ethers.js

1. Install Ethers.js in your project:

   npm install ethers
