Full Stack Developer - Crypto Currency Exchange

The objective of this project is to build a fully functional, web-based crypto trading platform with robust integration for cryptocurrency trading, including spot and futures markets. The platform will be a white-label solution with the capability of supporting various centralized exchanges (CEXs), such as Binance, and providing a seamless experience for users to trade, track their portfolio, and manage their funds. The platform will have features like secure user registration, two-factor authentication (2FA), market data integration, wallet management, fee structure, and more. Additionally, the platform will allow for on-ramping via MoonPay for easy fiat-to-crypto purchases, as well as the integration of multiple blockchain networks for withdrawals. Objectives User-Friendly Trading Terminal: To create an intuitive platform that makes cryptocurrency trading accessible for both novice and advanced users. API Integration: To integrate with Binance and potentially other exchanges for liquidity, real-time price feeds, order books, and market data. Security and Compliance: To implement strict security measures to protect users' sensitive data, transactions, and provide 2FA for added security. Monetization Strategy: To create a sustainable revenue model using fees on trades, withdrawals, and premium subscriptions. Web Responsiveness: To ensure the platform works seamlessly across desktops, tablets, and mobile devices. Blockchain Integration for Withdrawals: To support multiple blockchain networks (e.g., Ethereum, Bitcoin, Binance Smart Chain) for secure withdrawals. Key Features and Functional Requirements 1. User Interface (UI) Dashboard The dashboard should be the central hub for all user activities and must present real-time market data, such as live price charts, trading pairs, order books, recent trades, and portfolio balances. Spot Trading and Futures Trading should be easily accessible, with a clear distinction between the two modes. An interactive charting tool (e.g., TradingView or custom) should be integrated, displaying various timeframes, technical indicators (RSI, MACD, Bollinger Bands), and custom chart overlays. Order Management System Users should be able to place, modify, and cancel orders through a simple, user-friendly interface. Support for multiple order types: Market Orders: For immediate execution at the best available price. Limit Orders: For specifying a desired price before execution. Stop-Loss Orders: To minimize losses in volatile markets. View order history, active orders, and open positions, with real-time updates and visual cues (e.g., order status, pending orders). Portfolio Management The portfolio page should display all held assets (crypto/fiat), their respective balances, historical performance, and a breakdown of gains/losses. It should be possible to track portfolio performance over various time frames (24h, 7d, 1m, etc.), with charts showing asset growth. Transaction history for deposits, withdrawals, and trades should be easily accessible. Web Responsiveness Mobile-first design: The platform must be designed with mobile devices in mind first, ensuring optimal usability on smaller screens (smartphones/tablets). The UI should be adaptive, automatically resizing and adjusting for desktop, tablet, and mobile devices. Touch-optimized UI for mobile users to place orders, interact with charts, and manage their portfolios with ease. Customizable UI Users should be able to customize their dashboard layout (drag-and-drop widgets), choose the theme (light/dark mode), and set up price alerts. Allow for customizing charts, including different chart types (candlestick, line chart, OHLC) and adjusting the timeframes. 2. User Account Management Sign Up / Registration Users will register with basic information (email, username, password). After registration, users will be prompted to verify their email for account security. Social Media Logins: Allow users to register/sign in via their Google, Facebook, or other OAuth-based providers for quick onboarding. Two-Factor Authentication (2FA) Users will be required to enable 2FA during registration or log in via an email or app-based solution (Google Authenticator, Authy, or SMS-based verification). 2FA will be required for sensitive actions such as withdrawals, password changes, and account recovery. KYC (Know Your Customer) Depending on jurisdiction and platform compliance requirements, users may need to complete KYC verification by uploading government-issued ID and a selfie for identity confirmation. KYC will be linked to the registration process, enabling full account access only after completion. Account Settings Users should be able to update their profile details, password, and security settings from the account settings page. Include the ability to link API keys for users who wish to trade programmatically. 3. API Integration Market Data Fetch real-time price feeds (bid/ask, market price, 24h volume) for all listed trading pairs. Integrate order book data and trade history from Binance and other supported CEXs. Trading Operations Provide seamless order placement, cancellation, and modification functionality via integrated APIs from Binance and other exchanges. Support for Spot and Leverage (Margin) trading via the API. Integrate real-time order matching and execution. Blockchain Integration for Withdrawals Integrate popular blockchain networks (Bitcoin, Ethereum, Binance Smart Chain, etc.) for withdrawals, allowing users to withdraw funds to their wallets. Withdrawal fee structure should be dynamic, taking into account the network conditions for each supported blockchain. Provide real-time withdrawal status updates, including blockchain transaction ID. On-Ramping via MoonPay or Similar Integrate MoonPay for fiat-to-crypto purchases, allowing users to buy crypto using credit cards, bank transfers, or other fiat payment methods. Allow users to purchase popular cryptocurrencies (BTC, ETH, USDT, etc.) directly through the platform. 4. Security Features Authentication & Authorization Use OAuth2 for user login and JWT (JSON Web Tokens) for session management and user authentication. Secure password storage using bcrypt or Argon2 encryption. Data Encryption All sensitive data (passwords, API keys, transaction details) must be encrypted in transit using SSL/TLS encryption. End-to-end encryption for sensitive communications. Security Alerts Notify users via email or SMS if there is suspicious activity such as failed login attempts or unauthorized withdrawals. Regular Security Audits Perform regular penetration testing to identify vulnerabilities, and apply patches as needed. 5. Monetization Features Fee Structure Implement a fee model based on: Trading fees (percentage-based on each transaction). Withdrawal fees for cryptocurrency withdrawals, based on blockchain network fees. Subscription fees for premium features (advanced charting tools, lower trading fees, priority support). Display a clear breakdown of all fees for each trade and withdrawal to ensure transparency. Referral Program Implement a referral program where users can invite others to join the platform and earn a percentage of the trading fees generated by their referrals. Technical Specifications Frontend: Built with React.js or Vue.js to ensure fast, dynamic updates without page reloads. Integration with TradingView or custom charting solutions for interactive charts. Mobile-first responsive design with CSS Flexbox/Grid for layout management. Backend: Built with Node.js (Express) or Python (Django/Flask) to handle API requests, user authentication, and integration with Binance (or other CEXs) for liquidity, MoonPay, and blockchain networks. PostgreSQL/MySQL database for storing user data, transactions, and account details. Redis for session management and caching real-time market data. Security: TLS encryption for all sensitive communication. Database encryption for sensitive data at rest.
