TradeX - CryptoTradingPlatform

A full-stack cryptocurrency trading platform that empowers users to buy, sell, and trade digital assets like Bitcoin and Ethereum seamlessly. The platform leverages real-time market data, integrating the CoinGecko API to provide live price updates, market trends, and actionable insights for informed trading decisions.

For secure and efficient transactions, I integrated Razorpay and Stripe payment gateways, ensuring users can deposit and withdraw funds with confidence. User security is further reinforced with JWT-based authentication, allowing safe account management and access control.

To enhance user experience, I incorporated the Gemini API to build an intelligent chatbot, offering quick responses to trading queries and assisting users in navigating the platform.

The backend is powered by Spring Boot, providing robust, scalable, and high-performance services, while the frontend is built with React.js, delivering a smooth, responsive interface for executing trades, managing portfolios, and monitoring transactions in real-time.

This platform combines cutting-edge blockchain integration, secure payment processing, and AI-driven assistance to offer a comprehensive and user-friendly cryptocurrency trading experience.
