Oct 1, 2025October 2025 focused on strengthening reliability and scalability for Ledger Live's multi-asset workflows through targeted feature work, core bug fixes, and expanded test coverage. Key features delivered include: - Coin Monitoring: isolated per-currency runs (--isolated) with improved input validation and asynchronous execution, plus updates to scheduling defaults and tests. This reduces cross-currency interference and improves fault isolation across 100+ assets. - Polkadot Broadcast Core Fixes: refactored and fixed the broadcasting flow, corrected operation hashing, and implemented network/context adjustments to ensure accurate and timely broadcasts. - Polkadot Broadcast Test Coverage and Reliability: expanded tests for fees, signatures, and extrinsics with fixtures and currency handling to raise regression safety. - SUI Token Asset Handling Improvements: enhanced SUI coin module to correctly identify/build sub-accounts for SUI tokens using the crypto assets store and dynamic currency IDs; includes lint cleanup. Overall impact and accomplishments: - Increased system reliability and scalability for multi-asset monitoring and cross-chain broadcasts - Higher confidence in deployments due to broader test coverage and targeted fixes - Improved developer productivity through clearer change iterations and lint-driven code quality Technologies/skills demonstrated: - Async runtime improvements, input validation, feature flag usage (--isolated), and per-currency isolation - Test-driven development with fixture-based coverage and end-to-end scenarios for Polkadot and SUI modules - Cross-chain broadcasting workflows, linting, and code quality practices
