I developed a unified design system that maintains consistency between the mobile app and web platform, ensuring a seamless transition between devices. The interface features a dark theme for better readability, intuitive navigation for effortless transactions, and real-time data visualization for informed decision-making. Security elements, such as two-factor authentication prompts and secure transaction indicators, were integrated into both platforms. The web dashboard was designed with an interactive market overview, trading charts, and a streamlined coin swap system, ensuring an optimal user experience on larger screens.
