During October 2024, Tapio Vessa developed and refined wallet funding user experiences for the coinbase/onchainkit repository, focusing on both accessibility and UI consistency. He built a new Fund component using React and TypeScript, streamlining navigation and aligning interface elements for a smoother funding flow. Tapio enhanced accessibility by adjusting button text color and migrated the UI to a light theme for improved visibility, while also addressing spacing and alignment issues in key sections. His work emphasized maintainable front end development, incorporating UI/UX design principles and code quality improvements, resulting in a more robust, accessible, and user-friendly wallet funding interface.
