Jan 1, 2026January 2026 monthly summary for trezor-firmware: Focused on improving Tron transfer UX, expanding TRC20/USDT support on Shasta, and tightening code-generation reliability. Delivered functional Tron transfer flow enhancements, added TRC20/USDT handling on Shasta, and fixed code-generation string handling to prevent syntax errors. Also applied a transfer-label hotfix to ensure UI actions reflect user intent. These changes increase asset support, reduce production risks, and lay groundwork for Ethereum-like interface reuse across Tron features, driving business value and smoother future iterations.

Dec 1, 2025Monthly Summary – December 2025 (trezor/trezor-firmware) Overview: The month focused on expanding external smart-contract interaction capabilities while hardening address handling to improve reliability and user experience when interacting with TRON-based contracts. Key features delivered: - TRON TriggerSmartContract support enabling blind signing and showing only the contract address to users; added USDT/USDD transfer functionality with testing completed. Note: fee layout is imperfect and slated for future refinement. (Commit: fa41268709755f5ff3305f787e6e58c80b68cad1) Major bugs fixed: - Address chunkification reliability improvements in Bolt and Caesar (and Eckhart) to prevent chunks from being overwritten or miscomposed in edge cases. (Commit: 9b99395e863827bd9e901bb269c9d4b5840b0379) Overall impact and accomplishments: - Expanded on-device TRON contract interaction capabilities with secure, user-friendly UX (blind signing with address-only disclosure) and validated transfer flows for USDT/USDD. - Improved firmware reliability in edge cases for address handling, reducing potential user-visible issues and lowering support friction. - Delivered concrete, test-backed changes that strengthen ecosystem interoperability while setting the stage for a future follow-up on fee layout refinement. Technologies/skills demonstrated: - Embedded firmware development (C/C++), secure signing workflows, and testing practices for contract interactions. - Cross-component debugging and fixes in Bolt, Caesar, and Eckhart to ensure robust address chunkification. - Quality-focused commit hygiene and traceability for performance reviews.

Nov 1, 2025November 2025 delivered targeted UI/UX polish in trezor-firmware to streamline contract interactions and improve readability. Key enhancements included removing the warning screen for select non-ERC20 contract calls and typography refinements for Stellar amount and Bitcoin lock time, resulting in clearer information presentation and reduced user friction. Font rendering fixes were applied to correct the Stellar amount font on T3W1 and update the Bitcoin lock datetime font. A changelog entry (6032) was added to document the changes. These updates strengthen product usability and accessibility, and support clearer transaction flows. Cross-module collaboration (eckhart, Stellar) ensured UI consistency across components.
