Decentralized Auction House

A decentralized auction platform developed using Solidity for smart contracts and React.js for the frontend interface.

Features

• User Authentication: Allows users to sign up and log in to the platform.
• Add Items: Users can list items for auction with a minimum bid requirement.
• Place Bids: Participants can bid on available auction items.
• Buyout Option: Allows immediate purchase of an item at the buyout price.
• Responsive Design: Ensures a seamless experience across different devices.

Setup Guide

Backend Setup:

Ensure you have Node.js, Truffle Suite, and Ganache installed on your machine to proceed with the following steps:

1. Start Ganache:

   • Open Ganache and start a local blockchain instance.

2. Compile and Deploy Contracts:

   • Navigate to the backend directory:

     cd backend

   • Compile the smart contracts:

     truffle compile

   • Deploy the contracts to the local blockchain:

     truffle migrate

     Or, to reset the state of previously deployed contracts:

     truffle migrate --reset

3. Integrate Contract with Frontend:

   • Copy the contract's JSON file to the frontend:

     cp /backend/build/contracts/DecentralizedAuction.json /frontend/src/

4. Finalize Backend Setup:

   • Ensure all steps are completed without errors.

Frontend Setup:

Ensure you have npm installed to manage dependencies.

1. Prepare the Frontend Environment:

   • Change to the frontend directory:

     cd frontend

   • Install necessary dependencies:

     npm install

2. Launch the Frontend Application:

   • Start the application:

     npm start

   • This will open the web application in your default browser, typically accessible at http://localhost:3000.

3. Verify Operation:

   • Interact with the application to ensure all functionalities such as adding items, bidding, and buyout are working correctly.

Additional Information

• Ensure your browser has the MetaMask extension installed and connected to the local blockchain provided by Ganache to interact with the deployed contracts.
• The platform can be extended or modified to include additional features such as a more advanced bidding mechanism or integration with real-world auction standards.
