Worked on enhancing wallet synchronization reliability within the UnstoppableSwap/core repository, focusing on backend development using Rust and asynchronous programming techniques. Addressed a persistent issue where errors in the refresh_wallet_task were previously ignored, leading to silent failures and challenging debugging. Introduced explicit error logging to ensure that synchronization issues are now surfaced promptly, improving both observability and the speed of troubleshooting. This targeted reliability fix improved the maintainability of the wallet sync process without altering existing behavior. Emphasized robust error handling throughout the update, resulting in reduced mean time to resolution for wallet-related incidents and a more transparent operational workflow.
