Worked on BlueWallet’s hardware wallet signing flow, focusing on enhancing the usability and security of the signed transaction hex display. Using React Native and TypeScript, implemented a non-editable, scrollable hex field to ensure transaction data remains readable and protected from accidental edits during signing. This UI/UX improvement addressed the challenge of displaying lengthy hex strings within constrained mobile layouts, reducing the risk of user errors and increasing confidence in hardware wallet interactions. Maintained strong commit hygiene and traceability throughout the process. The work contributed to a more stable signing experience and aligned with best practices for secure mobile wallet development.
