Trezor firmware

This commit refactors how Trezor firmware handles unknown Ethereum tokens when showing transaction details on screen. Previously, if a transaction involved an unknown token, the device showed one generic warning. After this change, the code can detect and warn about multiple unknown tokens within a single transaction's data. It is a defensive code improvement rather than a fix for a known exploit.

This commit updates the Trezor Ethereum app's 'clear signing' feature so it can handle data formats that slice inside arrays or structs (for example, taking only a portion of a list). It is a small feature addition, not a fix for a known security bug. There is no evidence in the commit or supplied references that this resolves an active vulnerability.

This commit is a feature expansion for Trezor's Ethereum 'clear signing' system, which decodes smart-contract call data so users see human-readable details instead of raw hex. It adds support for dynamic Solidity types such as strings, byte arrays, structs, and arrays. The change is large and refactors how transaction data is parsed and presented. It does not appear to be a disclosed security fix, but because it handles untrusted transaction data, any parsing bugs could in principle let a malformed transaction bypass warnings or crash the device. The diff itself shows explicit bounds checks and validation, which is a positive sign, but the new code paths are complex and have not been externally audited in the provided materials.

This commit only adds new test cases for Ethereum transaction signing on Trezor hardware wallets. It includes sample swap transactions from services like 1inch, LiFi, and Uniswap, plus a large-data test case. There is no change to the actual firmware or wallet code—only test data and a test list are added. It does not introduce or fix a security vulnerability.

This commit fixes how Trezor displays details for certain 1inch cryptocurrency swap transactions. Previously, the device tried to interpret a parameter called 'pools' as a list of plain numbers, but it actually contains packed binary data. The change makes the device show the raw bytes as hexadecimal instead of trying to decode them as numbers. This is a display/clarity fix rather than a direct theft-of-funds bug, but mis-displaying swap details could in theory help an attacker trick a user into approving a malicious transaction.

This commit only updates expected test screenshots (called 'fixtures') for the Trezor firmware's user-interface test suite. It does not change any firmware code, cryptographic logic, or device behavior. The updated hashes reflect new/altered test cases for Ethereum transaction signing, including 'clear_sign' scenarios for Uniswap and LI.FI swaps, plus routine hash changes for existing token approval and definition tests across languages. There is no direct security issue in this commit itself.

This commit simply adds two new countries, South Africa and the United Arab Emirates, to the regulatory information screen on Trezor's Eckhart hardware wallet layout. It includes new flag icons, updates the list of regulatory zones, and refreshes automated test snapshots. There is no security-relevant change.

This commit is a user-interface polish change for the Trezor hardware wallet's homescreen. It changes when notification-related buttons and hints appear on screen, making them show up only after a small LED indicator toggles, unless animations are disabled or the notification is an alert. There is no security-relevant behavior in the change.

This commit is a routine user-interface cleanup for the Trezor hardware wallet's battery icon. It removes an older 'HomescreenBar' display mode and replaces it with a simpler 'AlwaysIconOnly' mode, while also dropping an alignment option. There is no indication in the commit that this fixes a security bug or changes security behavior.

This commit is a user-interface refresh for the Trezor T3W1 device homescreen. It adds a battery icon, a connection indicator, and makes notification labels interactive when relevant. There is no direct evidence of a security vulnerability being fixed or introduced; the changes are primarily cosmetic and structural.

This commit makes small visual adjustments to the Trezor hardware wallet's homescreen layout. It tweaks pixel alignment of status icons and fixes how a shadow behind a scrolling label moves during animation. There is no security-relevant change.

This commit is a straightforward performance optimization for the user interface on Trezor's newer 'Eckhart' layout. It pre-calculates and stores values like battery percentage text and page counter positions so they don't have to be recomputed every time the screen is redrawn. It also fixes a minor visual alignment issue with a small connection indicator dot. There is no indication this change fixes a security vulnerability.

This is a routine build-fix refactor for the Trezor hardware wallet's bootloader UI. It removes the 'const' keyword from a few Rust functions and splits a battery icon rendering helper so the bootloader build succeeds. There is no security-relevant change visible in the diff.

This commit is a user-interface feature for the Trezor hardware wallet. It adds a small visual indicator (a connection icon) next to the 'Connected' / 'Disconnected' status in the device menu and makes the menu refresh when USB or Bluetooth connection state changes. There is no evidence in the diff of a security vulnerability, exploit, or bug fix.

This is a routine UI layout fix for the Trezor hardware wallet. It adds missing width-calculation helpers to a 'Hint' widget, removes an unused background padding object, and tidies how a page-counter is rendered. There is no security-relevant change visible in the diff.

This is a small internal code cleanup in the Trezor firmware's battery indicator. It changes the battery charge level from an optional value (which could be missing) to a regular number that defaults to 0. There is no security issue visible in the change.

This commit adds a new on-screen status icon for the Trezor hardware wallet's Eckhart layout. The icon simply shows whether the device is currently connected via USB or Bluetooth. It is purely a user-interface change and does not alter how the device handles secrets, transactions, or security checks.

This commit only updates a test data file (tests/ui_tests/fixtures.json) containing expected hash values for user-interface tests. It does not change any firmware code, cryptographic logic, or device behavior. There is no security-relevant change visible in the diff.

This is a one-line change to a test file. It loosens a test assertion so that the homescreen check passes when the model name appears anywhere on screen, rather than requiring the screen content to be exactly the model name. It does not change any firmware code or device behavior.

This is a small internal code cleanup in the Trezor firmware's user-interface layer. It changes how one screen (the device menu) is launched so it uses a shared helper function called `interact`, rather than manually creating and tearing down a layout object. There is no indication this fixes or introduces a security vulnerability.

This commit only updates German translation text and the corresponding test snapshots (expected screen hashes). It removes a few old variant translations for the term 'hidden wallet' and standardizes it to 'Passphrase-Wallet'. There is no code change and no security relevance.

This commit is a simple internal rename of a field called 'method' to 'backup_method' across several files. It does not change how the device works, what data it stores, or how users interact with it. There is no security issue visible in this change.

This commit fixes a bug in the Trezor Python library's pairing flow for Trezor Host Protocol (THP). Before the fix, the code could check whether a device was already paired without first ensuring a communication channel was open. The fix explicitly opens the connection first and skips pairing if the device is already paired. The changelog describes it as fixing auto-connection after unlocking the device. There is no direct evidence in the commit of a security vulnerability being exploited.

This commit only updates translated text strings in the Trezor firmware. It adds new translations (for example, phrases like 'Confirm contract' and 'Intent' in several languages), fixes existing wording, and refreshes the translation signature file. There are no code changes that affect security, cryptography, or device behavior.

This commit is a routine maintenance update for translation files and test snapshots. It changes one French translation string, updates a cryptographic signature record for the translation set, and refreshes many expected visual test hashes. There is no code change that affects security functionality, and nothing in the commit suggests it fixes or introduces a vulnerability.
