Gaëtan Renaudeau contributed to LedgerHQ/ledger-live by engineering robust asset management and persistence features across desktop and mobile platforms. He modernized cryptography libraries, refactored token APIs, and integrated a scalable CryptoAssetsStore, enabling reliable multi-coin support and offline-ready data. Using TypeScript, JavaScript, and React, Gaëtan streamlined build systems with Rspack, improved CI stability, and optimized performance through targeted code cleanup and dependency upgrades. His work included enhancing test automation with Playwright and Jest, strengthening error handling, and maintaining cross-platform consistency. The depth of his contributions is reflected in improved maintainability, reduced technical debt, and a more resilient, scalable codebase.

Aug 1, 2025For 2025-08, delivered critical feature cleanups and security enhancements across Ledger Live (LedgerHQ/ledger-live). Key initiatives include removing the deprecated LiveQR account import across Desktop and mobile to reduce maintenance burden and security risk, and simplifying the build by dropping the qrloop alias from Vite. In parallel, modernized cryptography libraries across the monorepo to @noble/curves to standardize crypto operations, and added comprehensive SSL helper unit tests to bolster reliability. These changes reduce technical debt, tighten security, and create a cleaner, more maintainable codebase that supports faster iteration and fewer regressions.
