Part 7/12:
Closed Source & Some Limitations: Limited call data visibility unless "blind signing" is enabled.
Display Capabilities: Can show EIP712 domain and message hashes when configured properly, which is excellent.
Call Data: Shows raw call data but in an inconvenient format.
Recommendation: Better than many, but the limited transparency and proprietary firmware are drawbacks.
Ledger Flex:
Better UI & Usability: Larger screen, better button ergonomics, secure screen (verifying exactly what's on display).
Strong Display of Signatures: Shows domain hash and message hash, making verification easier.
Call Data: Decodes nested call data effectively but still shows it in a disguised format.
Trade-offs: Closed source, proprietary chip.
