Summary

  • GetBip85Mnemonic now returns Success — mnemonic shown on device screen only, never sent over USB
  • Bip85Mnemonic message retained for wire compatibility with older firmware
  • Security improvement: prevents host-side mnemonic exposure

Files

  • messages.proto — doc/comment updates only, no wire ID changes

Firmware dependency

Unblocks keepkey/keepkey-firmware BIP-85 display-only feature (7.14.0)

Test plan

  • protoc compiles cleanly
  • Backward-compatible — old firmware still sends Bip85Mnemonic

- GetBip85Mnemonic now returns Success (mnemonic shown on device only)
- Bip85Mnemonic message retained for wire compatibility with older firmware
- Mnemonic never leaves device over USB

Security improvement: prevents host-side mnemonic exposure.
