The short version

What changed, and why it matters

This commit changes how Ethereum addresses are visually displayed on Trezor devices. When the optional 'chunkify' feature is enabled, the '0x' prefix is now shown as a separate chunk from the rest of the address, making it easier for users to read and verify addresses. There is no direct security vulnerability being fixed here; it is a user-interface improvement that may slightly reduce the chance of user verification mistakes.

Recommended action

No security action required. Treat as a normal UI/UX improvement. Reviewers may optionally verify that the added `assert addr.startswith('0x')` cannot be triggered by malformed inputs, though the address is produced internally by `address_from_bytes`.

Security signals we found

01

UI display change only; no cryptographic or authorization logic modified

02

Address string padded with whitespace when chunkify enabled to alter visual grouping

03

QR-code and returned address values remain unchanged

04

No input validation, parsing, or signing code changed

05

No vendor disclosure of security relevance in commit message or changelog

refactor(crypto): pass static public key to `noise_xxpsk3_*_init()`

This commit changes how a cryptographic library sets up secure connections. Previously, the code automatically calculated the public key from the private key. Now, the caller must provide the public key directly. This is a code-quality ref…

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.
