The short version

What changed, and why it matters

This commit hardens how Keystone 3 handles Solana signing requests. Previously, the device partly trusted an external 'sign type' flag from the wallet app to decide whether a QR code contained a transaction or a plain message. The patch now inspects the actual bytes: if they look like a complete transaction it is treated as a transaction; if they start like a transaction but have extra hidden bytes it is rejected; otherwise it is treated as a message. It also adds a warning banner when a Solana message cannot be fully parsed, so the user knows they are 'blind signing'. A small UI fix also makes the camera scanner resume correctly after an error instead of getting stuck.

Recommended action

Treat this as a security-hardening fix and ensure it is included in the next firmware release. Review the classify_payload() logic for completeness, especially edge cases around off-chain message v0 and versioned transactions, and verify the UI warning is shown consistently for all raw message paths.

Security signals we found

01

Replaces trust in external sign-type metadata with byte-level payload classification

02

Rejects malformed transactions that contain a valid transaction prefix followed by hidden trailing data

03

Prevents a transaction from being displayed and signed as a plain message

04

Adds a blind-sign warning for unparsed Solana messages

05

Fixes scanner UI not resuming after an error
