Worked on the OneKeyHQ/app-monorepo, focusing on enhancing the reliability of the signing flow and ensuring data fidelity within the Sui KeyringHardware component. Addressed a critical issue by modifying the signing path to return the raw signing result instead of a JSON string, which aligned the output with expected data formats and reduced parsing issues for downstream components. This change improved data integrity across the signing workflow and simplified integration for other parts of the application. Utilized TypeScript and full stack development skills to implement and test the fix, demonstrating attention to detail in maintaining robust and predictable data handling processes.
