The short version

What changed, and why it matters

This commit adds a new feature to the Keystone 3 hardware wallet: the ability to sign personal messages on the Tron blockchain, similar to how it already handles Ethereum personal messages. The change touches the Rust signing code, the C UI code that shows the message on the device screen, and the simulator. It is a feature addition rather than a bug fix, and there is no vendor statement that this is a security patch. The main security-relevant concern is that any new signing path must correctly validate what it signs and show it clearly to the user, otherwise a malicious app could trick the wallet into signing something the user did not intend.

Recommended action

Treat this as a feature commit, not a confirmed vulnerability. Reviewers should verify that (1) the personal-message prefix and hash exactly match the Tron/TRC-20 ecosystem convention expected by wallets, (2) the UI always shows the raw or UTF-8 message and the signing address before signing, (3) the signing path cannot be reached without user confirmation, (4) message length is bounded to avoid stack/heap issues, and (5) the refactor of sign_tx_request to return only the signature does not break any downstream consumer that previously expected a full signed transaction.

Security signals we found

01

New cryptographic signing path added for Tron personal messages

02

Message prefix follows Ethereum-style convention (\x19TRON Signed Message:\n + decimal length)

03

Signature format uses secp256k1 r||s||rec_id+27, same as Ethereum personal sign

04

UI adds a dedicated review screen for Tron personal messages

05

Parsing path derives a 'from' address from the xpub/derivation path for display

06

No input-length limits are visible in the new signing helper

07

No explicit domain/chain-id binding in the personal-message format

08

Refactor of existing Tron transaction signing to return signature-only for tx requests
