These changes increased release confidence, reduced flaky tests, and broadened platform coverage for future scalability.

September 2025: Delivered expanded Apex P support across multiple networks and devices, removed deprecated Nano S support for Near, and documented a fix for cross-feed behavior in app-exchange. Strengthened cross-repo collaboration and prepared for broader, faster future deployments with explicit build/config and Rust BP improvements.

June 2025 performance summary: Delivered cross-repo improvements focused on release automation, code quality, and device UX stability. Achieved a streamlined release process with reusable deployment workflows, maintained high readability, and ensured consistent UX across hardware configurations. Across LedgerHQ/app-exchange, LedgerHQ/ledger-secure-sdk, and LedgerHQ/speculos, the work reduces release risk, accelerates publishing, and enhances developer onboarding.

May 2025 performance highlights: packaging and path alignment for the Exchange Python client; test robustness improvements; swap test workflow and CI updates; Exchange client publishing enhancements with a dedicated publish flow; alignment updates reporting Exchange client changes from develop and a client version bump.

Monthly summary for 2025-04 focusing on key accomplishments in LedgerHQ/app-exchange. This period emphasizes stability improvements and correctness fixes in the exchange module, with test reliability and transaction routing enhancements.

March 2025 focused on delivering scalable, secure, and maintainable CI/CD for Ledger projects. Key features include standardized Rust CI with reusable workflows and integration of the Rust SDK across all Rust apps, plus CI/CD improvements for C applications with Ledgered-based discovery and recursive submodule checkout. Security and quality improvements tightened secrets handling and token sharing, and documentation updates captured architectural changes for Speculos. The work reduced build risks, improved feedback loops, and set a foundation for faster release cycles across Rust and C ecosystems.

February 2025 — LedgerHQ/app-exchange: Delivered comprehensive test coverage for Boilerplate swap functionality, updated CI to run tests, and laid groundwork for robust regression protection. No major bugs fixed this month. Business value: reduces deployment risk and accelerates safe releases by catching edge cases early.

January 2025 overview: Delivered critical hardware-target build support and stability enhancements across LedgerHQ apps, with targeted improvements for performance and reliability. Key work includes adding Stax and Flex build targets in the SUI-based ledger-app-database, linting stabilization, UI test snapshot updates for Near swaps, and CI workflow improvements for Near app tests. These changes reduce build friction, improve test reliability, and accelerate validation of new features, directly supporting time-to-value for hardware-target deployments and roadmap items.

December 2024 Monthly Summary for LedgerHQ. Focused on strengthening reliability of Near transaction flows, expanding test coverage, and clarifying system interactions between Ledger Live and Exchange App. Delivered measurable improvements in test stability, CI coverage, and maintainability, while ensuring metadata/config consistency in the Near app.

2024-11 monthly summary: Delivered across two repositories with a focus on expanding device compatibility, improving observability, and strengthening developer documentation. Key deliverables include Speculos PKI/API_LEVEL_22 support for S+/X+Stax/Flex devices (reflected in v0.11.0 CHANGELOG), Address Parsing Diagnostics with trace logging in App-Exchange, and comprehensive documentation updates (Documentation section linking Flow and APDU protocol docs; Mermaid flow diagram; renamed protocol.md to doc/protocol.md). These efforts enhanced emulator breadth, debugging reliability, and onboarding for contributors and customers.

2024-10 Monthly summary for LedgerHQ/app-exchange. This period focused on stabilizing the CI/CD pipeline, enabling Rust-based builds in CI, and strengthening NEAR testing configurations. The work delivered improves deployment reliability, reduces feedback cycles, and enhances test coverage for NEAR currency workflows.
