Jan 1, 2026Monthly summary for 2026-01 – trezor-suite: Key features delivered: - Implemented X-Suite-Platform header for all backend requests, enabling consistent backend context propagation and improved observability. (commits: 2aa654aba17ef5d130061883a980d33cc1fd4182) - UX and trading enhancements: hide sell fee preview until provider approval; add currentProviderMetadata to trading state; update selectedProviderMetadata on quote change; display sell/exchange form even with view-only wallet; show provider terms of use as soon as a quote is selected. (commits: 3938d5860fa7ef51f8a880a37d6351d868c93cb3, 3bf0afceb2f915dee97dff7fae05057e53d3c11b, e4a82f94586a0966dfea758c6d6bbc3cd50431ff, c8e4aa82d3b29738c50dd855a8399aefa7365fff, 77d3854968b5846cd5269c39de1590291f07211e) - End-to-end testing and reliability: introduced sell e2e test and efforts to stabilize Mobile/Trading E2E flows; enabled controls to reduce flakiness (e.g., slower e2e search, avoiding unnecessary UI animations in tests). (commits: 90b73bd1f81978d8dd863ed91182b27a2b5422a0, 6f25f4feb454d0aedaf9e43015b188e6731d7ce1, 30c7a0cf118a4375bcaa7c3b260aabfc952a7968) Major bugs fixed: - Initialize select nonce hack only once to prevent repeated initialization. (commit: 9efab1ea13d340677f0a99250330be8d34959782) - Fix failing Trading exchange E2E tests and related flakiness. (commit: 8b8fb3432bdb49d4b16df99be1821ae64153bf89) - Mobile Sell: Allow provider success to be set before WebView is closed; fix race in WebView lifecycle. (commit: 7d2c3469a1ae86bfdc733e3972136dafe5b7e2d5) - Fix act() warnings in module-trading unit-tests and module-onboarding unit-tests to reduce test noise. (commits: f1fe35a1a1b9beb9238b55ff6f2b6f1b1452d4e4, b49439a4f3af57f5ad71d17106b22d7a66fdd503) - Stabilize selectors and UI rendering: fix unstable selectAllAddressesForWallet and fix content overflow of CountryListItem.

(commit: 71faea78f0e62afda9f4102c77ecd085c4db9e50) Overall impact and accomplishments: - Significantly improved reliability and end-user experience in trading flows and mobile experiences, with stronger test coverage and reduced flakiness across E2E tests. The backend now propagates richer context for observability, enabling faster debugging and performance tuning. UX polish around terms of use, quotes, and view-only wallet flows reduces user friction and errors. These changes establish a more robust foundation for future trading features and platform integrations. Technologies and skills demonstrated: - TypeScript, React Native, Redux/RTK, and current platform architecture; enhanced observability and error handling through new provider metadata fields and thunk utilities; strengthened E2E test strategy and test stability; UI/UX refinements focusing on clarity and gating logic; and improved code quality through targeted bug fixes and refactors.

Delivered user-visible UX refinements (Mobile Trade: sort receive accounts; hide assets without a pair; hide slippage button when DEX is disabled) and country-of-residence settings with trading-form handling. Implemented comprehensive analytics for TradingQuoteReceived, provider changes, trade confirmations, and trading tab changes across Mobile Swap and Trade, enabling data-driven product decisions. Initiated modular refactor to trading-base components and introduced trading-residence state to support future enhancements. Also improved reliability with enhanced error logging, export utilities, and CI/test stability. These changes improve user adoption, decision quality, and release velocity while reducing risk.

Jul 1, 2025July 2025 highlights substantial improvements across trading and swap flows in trezor-suite, with a strong focus on stability, performance, and business value. Key features delivered include a comprehensive trading state refactor (Mobile Trade) and refactored trading selectors to improve correctness and maintainability, along with persistence for trading settings to reduce user friction. Mobile swap enhancements introduced display of receive and send balances, fiat values for the send amount, and robust quote/error handling including warnings when no quotes are available and Insufficient balance messaging. UI/UX improvements added animated primitives and a BottomSheetTextInput option, while maintaining reusability by extracting SendOutputsReviewScreen in Mobile Swap. Major fixes targeted stability and quality, including stabilizing the selectTradingExchangeProviders mock selector and removing invariant state from selectors. The team also advanced testing and platform readiness via E2E preloaded state, faster E2Es, onboarding initialization for E2Es, Expo upgrade to 53.0.20, and Jest noise reduction.Overall impact: smoother, more reliable trading and swapping experiences, quicker iteration cycles, and a solid foundation for future features. Technologies demonstrated: React Native, suite-native/suite-common patterns, persistent reducers, animated UI primitives, and enhanced E2E/testing practices.

Jun 1, 2025June 2025: Delivered substantial enhancements to the Mobile Trade workflow in trezor-suite, improving UX, reliability, and developer ergonomics. The work focused on enabling intuitive trading flows, safer trading via warnings, and stronger cross-component consistency. Notable improvements include new mobile trade navigation to the selected trade type, BTC-only and Read-only warnings, and an Exchange form with a broader Exchange UI component set. Architectural refinements and type exports were implemented to improve maintainability and reduce refactor risk. Real-time pricing support was added with Mobile Swap quotes, and a Gateway 21 footer was integrated to align with branding and usability standards. Geolocation awareness via useGeolocationCountryCode was introduced to tailor behavior for different regions. Test utilities and fixtures were stabilized to improve confidence in changes and reduce flakiness. Overall impact: Enhanced user trust and conversion in mobile trading, reduced regression risk through clearer module exports and key flow refactors, and accelerated feature delivery with a more modular UI component suite. The month also advanced alignment with business goals around international users and safer trading experiences.

Jun 1, 2025June 2025: Delivered substantial enhancements to the Mobile Trade workflow in trezor-suite, improving UX, reliability, and developer ergonomics. The work focused on enabling intuitive trading flows, safer trading via warnings, and stronger cross-component consistency. Notable improvements include new mobile trade navigation to the selected trade type, BTC-only and Read-only warnings, and an Exchange form with a broader Exchange UI component set. Architectural refinements and type exports were implemented to improve maintainability and reduce refactor risk. Real-time pricing support was added with Mobile Swap quotes, and a Gateway 21 footer was integrated to align with branding and usability standards. Geolocation awareness via useGeolocationCountryCode was introduced to tailor behavior for different regions. Test utilities and fixtures were stabilized to improve confidence in changes and reduce flakiness. Overall impact: Enhanced user trust and conversion in mobile trading, reduced regression risk through clearer module exports and key flow refactors, and accelerated feature delivery with a more modular UI component suite. The month also advanced alignment with business goals around international users and safer trading experiences.
