Worked on stabilizing wallet operations within the coinbase-wallet-sdk by addressing a critical bug affecting wallet send calls parsing. Focused on ensuring the 'calls' parameter was properly formatted before dispatching wallet send requests, which improved the integrity and reliability of wallet send RPC paths. This fix reduced the risk of failed transactions caused by malformed data and enhanced user trust in wallet send flows. Demonstrated strong debugging and code review skills throughout the patch creation process. The work was carried out using TypeScript and SDK development practices, with all efforts concentrated on repository-focused improvements during the month-long contribution period.
