Part 8/12:
Verdict: Lean towards "Recommended with a big asterisk"; best for signing data but not ideal for raw call data verification.
Rating: 8/10.
6. OneKey Pro
Features: Open source but flagged for non-reproducible build verification.
Experience: Very user-friendly with air-gapped mode, haptic feedback, and offline key generation.
Data Visibility: Shows structured EIP712 data (not the full hashes) and the transaction call data.
Limitations: Call data isn't decoded, and the implementation is somewhat inconsistent.
Recommendation: Good for technical users comfortable verifying call data manually.
Verdict: Suitable for targeted security research if open source concerns are acceptable.
