CrowdFunder DApp

This repository contains the full decentralized application (DApp) for CrowdFunder, including both the smart contract backend and the React frontend. The smart_contract folder holds the Solidity smart contracts and Hardhat configuration, while the client folder contains the React application for interacting with the smart contracts.

Prerequisites

Before you begin, ensure you have the following installed:

• Node.js
• Yarn
• An Ethereum wallet like MetaMask configured for the Sepolia network.

Setting Up the Environment

1. Clone this repository and navigate into it:

   git clone https://your-repository-url.git
   cd your-repository-directory

2. Install dependencies in both the smart contract and client directories:

   # Install dependencies for the smart contract
   cd smart_contract
   npm install
   
   # Install dependencies for the client
   cd ../client
   npm install

Smart Contract Usage

Configuration

1. Copy the .env.example file to a new file named .env and fill in the necessary environment variables:

   PRIVATE_KEY=<Your-Sepolia-Wallet-Private-Key>
   ETHERSCAN_API=<Your-Etherscan-API-Key>
   

Compiling the Contract

1. Navigate to the smart_contract folder and run the following command to compile the smart contract:

   npx hardhat compile

Deploying the Contract

1. To deploy the contract to the Sepolia network:

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

   Note the contract address output by this script; you'll need it for the client setup.

Client Application Setup

Configuring the Contract Address

1. In the client directory, navigate to the src/constants/index.jsx file.
2. Open the file and update it with the contract address you obtained during the deployment.

Starting the React Application

1. Make sure you are still in the client directory.
2. Start the React development server:

   npm start

   This will launch the application on http://localhost:3000.

Interacting with the DApp

1. Ensure your MetaMask is connected to the Sepolia network.
2. Use the React application to interact with your deployed smart contract.
