MyToken Dapp

MyToken Dapp is a decentralized application (DApp) that demonstrates the creation, minting, and transferring of an ERC20 token. The project includes both a backend (smart contract) written in Solidity and a frontend built with React and Material-UI. This DApp allows users to mint new tokens, transfer tokens to other addresses, and view transaction history and balances.

Features

1. Mint Tokens: Users can mint new tokens to their address.
2. Transfer Tokens: Users can transfer tokens to another address.
3. View Balance: Users can view their token balance.
4. View Recipient Balance: Users can check the token balance of another address.
5. Transaction History: Users can view the history of minting and transferring transactions.

Technologies Used

• Solidity: For writing the smart contract.
• Hardhat: For compiling, deploying, and testing the smart contract.
• React: For building the frontend.
• Material-UI: For styling the frontend components.
• Ethers.js: For interacting with the Ethereum blockchain.
• Infura: For connecting to the Ethereum network.

Prerequisites

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

• Node.js and npm installed.
• A MetaMask wallet installed in your browser.
• An Infura account for connecting to the Ethereum network.

Getting Started

Follow these steps to set up and run the project locally.

1. Clone the Repository

git clone https://github.com/YOUR_GITHUB_USERNAME/MyTokenDapp.git
cd MyTokenDapp

2. Install Dependencies

Navigate to the project directory and install the necessary dependencies:

npm install

3. Set Up Environment Variables

Set the following environment variables in your terminal before running the Hardhat scripts:

export INFURA_API_KEY=YOUR_INFURA_PROJECT_ID
export SEPOLIA_PRIVATE_KEY=YOUR_PRIVATE_KEY

4. Compile the Smart Contract

Use Hardhat to compile the smart contract:

npx hardhat compile

5. Deploy the Smart Contract

Deploy the smart contract to the desired network:

npx hardhat run scripts/deployer.js --network sepolia

Note: Replace sepolia with your desired network if necessary.

6. Run the Frontend

Start the frontend development server:

npm start

Open your browser and navigate to http://localhost:3000 to interact with the DApp.

7. Interact with the DApp

• Mint Tokens: Enter the amount to mint and click "Mint".
• Transfer Tokens: Enter the recipient address and amount to transfer, then click "Transfer".
• Check Recipient Balance: Enter the recipient address and click "Check Recipient Balance".
• View Transaction History: View the list of minting and transferring transactions.

Project Structure

• contracts/: Contains the Solidity smart contract MyToken.sol.
• scripts/: Contains the deployment script deployer.js.
• src/: Contains the React frontend code.
  • App.js: The main React component.
  • MyToken.json: ABI of the deployed smart contract.
