Abstract: The increasing adoption of cryptocurrencies has transformed digital finance, leading to the need for reliable, real-time information systems for users and investors. However, most existing applications provide either limited data visualization or lack personalization and security. This paper presents Coin Hub, a full- stack cryptocurrency information and management platform designed to deliver seamless access to live coin data, user specific dashboards, and a secure, responsive interface. The system is built using Java Spring Boot for backend development and React.js for frontend implementation, supported by a MySQL database for structured storage and RESTful APIs for smooth communication. The application provides real-time and intuitive visualization of cryptocurrency trends, offering a practical demonstration of end-to-end web engineering. Extensive testing through Postman, load-testing tools, and frontend validation confirmed the robustness, scalability, and synchronization, secure authentication and responsiveness of the system. Coin Hub demonstrates the integration of modern full-stack technologies for efficient information systems in the evolving world of digital finance.
