ETH Math Quiz

This project is a decentralized application (DApp) offering math quizzes powered by Ethereum smart contracts. It aims to enhance knowledge of DApp development.

Features

• Math quizzes interacting with Ethereum smart contracts.
• Built using Solidity, Hardhat, and ethers.js.

Tech Stack

• Frontend: TypeScript, React
• Backend: Solidity, Hardhat, ethers.js
• Blockchain: Ethereum (Polygon Amoy testnet)

Installation

1. Clone the repository:

   git clone https://github.com/nabeo114/eth-math-quiz.git
   cd eth-math-quiz

2. Install dependencies:

   cd frontend
   npm install
   cd ../hardhat
   npm install

3. Configure environment variables:

   In the hardhat directory, create a .env file:

   INFURA_API_KEY=your_infura_api_key_here
   ACCOUNT_PRIVATE_KEY=your_private_key_here

   In the frontend directory, create another .env file:

   INFURA_API_KEY=your_infura_api_key_here

   Note:

   • The ACCOUNT_PRIVATE_KEY is used for deploying contracts; ensure it holds MATIC tokens from the Polygon Faucet.
   • The INFURA_API_KEY is required to connect to the Polygon Amoy testnet via Infura. Obtain it from Infura.

4. Compile the smart contracts:

   npm run compile

5. Deploy the contracts to the Polygon Amoy testnet:

   npm run deploy

Running the Frontend

1. Start the development server:

   cd ../frontend
   npm start
