Worked on enhancing cross-network log retrieval robustness for the ponder-sh/ponder repository by implementing Avalanche-specific block range error handling using TypeScript. Developed a dedicated test to validate block range limits and edge cases, ensuring reliable error detection and smoother analytics across blockchain networks. Extended the getLogsRetryHelper utility to parse Avalanche error messages and dynamically adjust retry logic, reducing failed fetches and monitoring gaps. Focused on backend development and error handling, the work improved the reliability of cross-chain analytics and enabled faster issue detection. Emphasized thorough testing practices to ensure the new features integrated seamlessly with existing blockchain infrastructure.
