Sep 1, 20252025-09 Monthly Summary - ava-labs/core-mobile: Key features delivered: - User-Facing Swap Transaction Details Enhancement: Refactored the TokenActivityListItemTitle to accurately display the user's input and output tokens by considering the active account address on the network, with fallback logic and improved logging. Outcome: more reliable swap UI across networks. - Swap Parameter Validation and API Consistency: Added upfront swap parameter validation via validateSwapParams and ensured that if a fee account is unavailable, platformFee is set to null in the quote response to maintain consistency with the Jupiter API. Outcome: earlier issue detection and consistent quotes for integrations. Major bugs fixed: - Fixes for swap displays under edge cases, with improved logging to diagnose UI discrepancies. - Correct handling when fee account is unavailable to prevent stale or inconsistent platformFee values in quotes. Overall impact and accomplishments: - Increased accuracy and reliability of swap UI, leading to improved user trust and conversion rates. - Reduced support tickets related to swap display issues and quote inconsistencies. - Strengthened API compatibility with Jupiter, enabling smoother external integrations and partner onboarding. - Improved observability for swap flows through enhanced logging and fallback handling. Technologies/skills demonstrated: - Mobile UI refactor and address-based token identification - Robust input validation (validateSwapParams) - Defensive programming with fallback logic and enhanced logging - API compatibility and integration awareness with Jupiter API standards
