PROFILE
Jérôme Prudent
Jean Prudent worked on the LedgerHQ/ledger-live repository, focusing on enhancing transaction data reliability and API resilience across multiple blockchain integrations. Over four months, Jean delivered a robust cross-chain pagination system for XRP and Tezos, refactored SUI coin operation retrieval for high-volume accounts, and addressed edge-case failures in XRP block queries. Using TypeScript, JavaScript, and Node.js, Jean implemented test-driven fixes and a configurable retry policy for API calls, reducing user-facing errors and improving data integrity. The work demonstrated depth in backend development and API integration, with targeted, low-risk changes that improved both user trust and maintainability of the codebase.

Feb 1, 2026February 2026 LedgerHQ/ledger-live monthly summary focusing on business value and technical achievements. Delivered a targeted bug fix to XRP block retrieval to handle non-positive indices, ensuring required properties (hash and timestamp) are returned for edge cases (height 0 and negative indices). This improves robustness and reliability of XRP data queries, reducing potential user-facing errors in XRP-related balances and history views. The fix was implemented as a focused change with minimal surface area (commit 5c66e359c1f1e51830d57366d3440dc58ecc46a1) and demonstrates strong ownership of data integrity in edge cases. Impact includes higher user trust, smoother XRP workflows in Ledger Live, and fewer support incidents related to XRP data retrieval.
