EAL6+ + Open Source
Trezor 

Open Source Pioneer with the Strongest Secure Element Certification

CryptoKeySafe Security Review

Trezor pioneered the hardware wallet category and remains the gold standard for firmware transparency. The Trezor Safe 5 is the first hardware wallet to combine an EAL6+ secure element with fully open source firmware, giving users and researchers the ability to independently verify every line of code that handles their private keys.

Strengths

  • Only wallet combining EAL6+ SE with fully open source firmware
  • Shamir backup provides superior seed phrase protection
  • Safe 5 color touchscreen with haptic feedback is a premium experience
  • 9,000+ supported assets across major blockchains
  • Transparent security model that welcomes independent auditing

Considerations

  • USB C only with no wireless or air gapped signing option
  • Safe 5 is relatively new compared to established Ledger lineup
  • No Bluetooth connectivity for mobile users
  • Trezor Suite companion app has fewer DeFi integrations than Ledger Live

Our Verdict

Trezor Safe 5 is the top recommendation for users who value transparency and verifiability. The open source firmware combined with EAL6+ certification means you do not have to trust Trezor. You can verify. For security professionals and technically minded users, this is the strongest available combination of hardware security and software transparency.
