Voting DApp

Overview

voting-dapp is a decentralized application (DApp) that allows users to vote securely on a blockchain network. This project is built using Solidity for smart contracts and integrates with a web-based frontend for user interaction.

Features

• Smart contract-based voting system
• Secure and tamper-proof votes
• Web3 integration for interacting with the blockchain
• Simple and user-friendly interface

Tech Stack

• Smart Contracts: Solidity
• Frontend: JavaScript, HTML, CSS, Bootstrap, and React
• Blockchain Interaction: Web3.js
• Development Environment: Hardhat/Truffle

Installation

Prerequisites

Ensure you have the following installed:

• Node.js
• MetaMask (for interacting with the blockchain)
• Hardhat

Steps

1. Clone the repository:

   git clone https://github.com/dappteacher/voting-dapp.git
   cd voting-dapp

2. Install dependencies:

   npm install

3. Compile the smart contracts:

   npx hardhat compile

4. Test the smart contracts:

   npx hardhat test

5. Deploy the contracts on Sepolia and replace the values based on "Configuration":

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

6. Start the development server:

   cd frontend
   npm install
   npm start

Configuration

Before running the application, update the contract address and Infura endpoint in the appropriate files:

1. Smart Contract Address:
   Replace your deployed contract address in the frontend config (e.g., src/App.js and .env file):

   const CONTRACT_ADDRESS = "YOUR_CONTRACT_ADDRESS";

2. Infura Endpoint:
   Update the Infura API URL in your environment file (.env):

   INFURA_API_URL=https://sepolia.infura.io/v3/YOUR_INFURA_PROJECT_ID
   

Note: Replace "YOUR_CONTRACT_ADDRESS" and "YOUR_INFURA_PROJECT_ID" with your own values.

Usage

1. Connect your MetaMask wallet.
2. Select or add a voting option.
3. Submit your vote securely on the blockchain.
4. View the live vote count.
