A production-ready full-stack decentralized application showcasing modern blockchain integration, real-time features, and enterprise-grade architecture patterns.

This project demonstrates a comprehensive Web3 platform combining prediction markets, staking mechanisms, and exchange functionality. The platform features seamless external integrations, real-time updates, and a robust RESTful API architecture designed for scalability and maintainability.

• Prediction Markets: Bull/Bear prediction system with live price feeds and automated round management
• Staking Platform: Multiple staking plans with automated earnings calculation and distribution
• External Integrations: Multi-chain support with secure third-party connections and transaction handling
• Exchange Dashboard: Real-time market tracking, portfolio management, and analytics
• Referral System: Complete referral tracking, rewards calculation, and user hierarchy management
• Transaction History: Comprehensive transaction logging with filtering and export capabilities
• Admin Dashboard: Full administrative controls for user management, withdrawals, and system monitoring
• Support System: Ticket-based customer support with message threading
• Real-time Notifications: Live updates and event broadcasting
• Authentication & Security: Secure user authentication with session management

• Modular Design: Clean separation of concerns with layered architecture (controllers, services, models)
• Middleware Pattern: Authentication, validation, and error handling middleware
• RESTful API: Well-structured API routes with versioning and comprehensive error responses
• Real-time Communication: Bidirectional communication for live updates
• Blockchain Integration: Secure external connections and transaction processing
• State Management: Global state management patterns for complex application flows
• Type Safety: Strong typing throughout the codebase
• Error Handling: Comprehensive error handling and logging strategies

Before you begin, ensure you have the following installed:

• Node.js (v16 or higher) - Download
• npm (comes with Node.js) or yarn
• Git - Download

npm install

cd backend
npm install
cd ..

Or use the convenience script:

npm run start-all

This will install dependencies for both frontend and backend, then start both servers.

From the root directory:

npm start

This will:

• Start the backend server on http://localhost:1357 (with mock data)
• Start the frontend development server on http://localhost:2468

Note: The backend uses in-memory mock data. All data will reset when you restart the server.

Terminal 1 - Backend:

cd backend
npm start

Terminal 2 - Frontend:

npm run client

Once both servers are running:

• Frontend: Open http://localhost:2468 in your browser
• Backend API: Available at http://localhost:1357/api
• Health Check: http://localhost:1357

This codebase showcases production-ready patterns including:

• Secure authentication flows with token-based sessions
• Real-time bidirectional communication
• Blockchain transaction handling and external integrations
• Responsive design with modern UI/UX principles
• Comprehensive error handling and validation
• Scalable architecture patterns suitable for enterprise deployment
• Clean code organization and maintainable structure

Perfect for evaluating technical depth, code quality, architectural decision-making, and understanding of modern software development practices.

Built with modern best practices and designed for scalability.
