Feb 1, 2026February 2026 — Ledger Live onboarding MVVM migration and testability improvements. Migrated onboarding components to MVVM to enhance structure, maintainability, and testability; added tests for the onboarding view model and flow to verify functionality; and performed code cleanup for readability. Impact: stronger onboarding foundation reduces regression risk, enables faster feature iteration, and improves reliability for new users. Foundations laid for easier maintenance and future enhancements. Notable commits: - 153417f619b0a966174674c1a0f630e6cc9d6c69 — feat: migrate sync onboarding companion component to mvvm - 6cbf0db20b366ccb2c02f532da24fe10cd9ec469 — feat: migrate LWM new seed panel to mvvm

Dec 1, 2025December 2025 monthly summary for Ledger Live: Delivered substantial onboarding and ledger sync enhancements with telemetry, implemented a robust ledger sync step within the two-step onboarding, and established a completion mechanism for nano LLD new device sync. Introduced AB testing feature flags to enable controlled experiments with Reb on Welcome redirects (lldrebornABtest) and no-device redirects (llmRebornABtest) to de-risk UI changes. Updated post-onboarding UX with a dedicated action row for completed devices and refreshed hub/text for clarity and consistency. Migrated critical onboarding flows and companion components to the new architecture (success step, desync logic, onboarding companion seed step, and useCompanionSteps) to improve maintainability and performance. Implemented tracking integration to support analytics and telemetry-driven decisions, along with reliability improvements such as default account handling in the receive flow after adding an account. Achieved code quality and stability gains through lint/typecheck/changeset/sonar fixes, Copilot improvements, and test stability enhancements, including fixes for useAddMember tests and removal of problematic useEffect dependencies.
