Part 11/12:
Most wallets reviewed balance security features with usability. Open source generally provides a higher degree of trust, as users and auditors can verify the code. However, open source alone isn't enough without proper decoding and display of transaction details.
Key takeaway: Never sign a transaction or message you do not understand, especially if your wallet does not prominently display the details or if you suspect obfuscation.
Conclusion
There is no perfect hardware wallet. They all involve trade-offs—between usability, security features, transparency, and data display. For security researchers and developers, prioritizing open source and call data verification is crucial.
