Keystone 3 firmware

This commit only adds and updates test code for error handling in the Tron app. It expands unit tests to check that various error types convert correctly and removes an unnecessary `mut` keyword from a test variable. There are no changes to production code or security-sensitive behavior.

This commit refactors how the Keystone 3 hardware wallet handles TRON (TRX) transactions. It switches the signing pipeline from accepting a custom JSON transaction description to accepting a raw protobuf transaction, and it tightens the HD path validation. The change is mostly a feature update for NuFi TRON support, but it also removes some address-derivation checks that previously ensured the transaction's 'from' address matched the wallet's key. That removal could, in theory, make it easier for a malicious companion app to ask the device to sign a transaction that does not belong to the wallet, though the companion app still needs to pass the wallet's master fingerprint and xpub checks. There is no explicit security bug or exploit shown in the diff, but the change is security-relevant because it alters the trust boundary between the host and the device.

This commit is a routine UI/translation cleanup. It removes the Polish language translation table, fixes a few non-English translations of the phrase "Cardano Native" to use the English wording, and makes a tiny code-style change in a font file. There is no visible change to transaction signing, cryptography, wallet handling, or any security-sensitive logic.

This commit fixes the build process for a software simulator used during development. It adds a missing dependency for the Sui cryptocurrency app, wraps a real-device bootloader update check so it is excluded from simulator builds, and provides a simulator-only stub that always returns 'no update needed.' There is no indication this change affects real hardware security or user funds.

This commit simply swaps the on-screen icon for the Keplr wallet. It updates a PNG image, its matching C-language embedded copy, and a hash file used to track assets. There is no code change, no security fix, and no behavior change beyond the new picture.

This commit adds a one-time reset of a 'recovery mode switch' flag during device startup. The change makes the device clear the recovery-mode marker if it matches an expected magic value and then saves the updated boot settings. Without more context, it looks like a hardening or bug-fix change that prevents a recovery-mode state from persisting unexpectedly across reboots, which could otherwise affect how the device boots or whether it exposes recovery features.

This commit fixes two minor UI issues. First, it corrects the displayed text for an Avalanche (AVAX) wallet derivation path so the placeholder for the account number is shown inside single quotes (X') instead of outside them, matching the actual BIP-44 path format. Second, it cleans up an incorrect include guard in a header file that was using the wrong macro name and an extra unnecessary #endif. Neither change affects security.

This commit is a pure code-formatting change. It removes an unnecessary line break in a Rust match arm, making the code style consistent with the surrounding code. There is no functional change, no bug fix, and no security relevance.

This commit changes two Japanese translation strings for Cardano-related labels in the Keystone 3 hardware wallet firmware. One string in a CSV file is updated from a katakana-only rendering to include the English word 'Cardano' with a Japanese suffix, and the matching compiled string in a C source file is updated the same way. There is no code behavior change, no security fix, and no vulnerability signal.

This commit fixes translation strings for a Cardano wallet label. It corrects mismatched language entries so that Spanish, Japanese, Korean, and Russian users see the label in their own language instead of seeing Korean, Chinese, or English text by mistake. There is no security change.

This commit is a tiny UI-only change for the NuFi wallet connection screen. It increases the declared size of an image array from 4 to 5 so that a fifth cryptocurrency icon (likely TRON/TRX) can be added. There is no security-relevant change visible in the diff.

This commit updates translation strings and adds a new Polish language file for the Keystone 3 firmware's user interface. It changes wording about TON wallet deletion and removes some obsolete TON-related labels, but it does not modify any security logic, cryptography, or code that handles secrets.

This commit removes a conditional compilation guard (#ifdef BUILD_PRODUCTION) around some software version-related function declarations in a header file. The stated purpose is simply to fix a build failure. There is no indication of any security issue in the change itself.

This commit simply adds TRON (TRX) as a supported coin icon for the NuFi wallet connection screen in the Keystone hardware wallet firmware. It is a routine feature addition with no visible security implications.

This commit is purely a code-formatting cleanup. It reorders an import, breaks a few long assert lines into multiple lines, and removes extra blank lines. There are no functional changes to the firmware or any security-relevant behavior.

This commit only adds unit tests for existing TON (The Open Network) message parsing code. It does not change any production behavior, fix bugs, or alter how the firmware handles real transactions. The tests verify that Jetton, NFT, comment, and error-conversion routines behave as already implemented.

This commit only adds text to two changelog files describing a new firmware release. It does not change any executable code, configuration, or security logic. There is nothing to exploit or patch in the commit itself.

This commit fixes a user-interface bug related to displaying the new USD₮0 (Tether) token symbol. It updates a generated font file so the ₮ glyph renders correctly, and corrects a function signature in the wallet connection screen so coin icons are passed as image descriptors instead of strings. There is no direct evidence of a security vulnerability being patched.

This commit is a routine rebranding update: it changes the displayed name and icon of a wallet partner from 'Zashi' to 'Zodl' across the user interface. It also includes a tiny, unrelated code-style fix in a boot-parameter function so the simulator build path is properly wrapped in #ifdef/#else/#endif. There is no security-relevant change.

This commit only adds a blank line to a changelog file. It contains no code changes, no security fixes, and no functional modifications. There is nothing here that could affect device security or user funds.

This commit only edits two changelog files. It changes the release date of version 2.3.10 and adds a note about a bug fix for signing shielded Zcash (ZEC) transactions. No actual source code is changed in this commit, so it cannot by itself introduce, fix, or exploit a security vulnerability.

This commit only adds a new changelog entry for firmware version 2.3.10 and bumps the build number in a version header. It does not change any executable code, cryptographic logic, or security behavior. There is no security issue visible in this commit.

This commit only changes a single version number in a header file, bumping the build number from 6 to 8. There is no functional code change, no bug fix, and no security-related modification visible in the diff.

This commit only adds a new changelog entry for firmware version 2.3.8 and bumps the build number in a version header file. There are no code changes, no bug fixes, and no security-related content.

This commit removes the Nabox wallet from an internal list of Ethereum-compatible (EVM) wallets in the Keystone 3 firmware's user interface. The title calls it a 'UI bug' fix. The change is one line: Nabox is no longer treated as an EVM wallet, which likely changes which blockchain options or connection flows are shown to users when they select Nabox. There is no direct evidence in the commit of a security vulnerability, exploit, or data leak.
