Last Reviewed: 2026-02

Summary Assessment

Trezor is a hardware-based self-custody device emphasizing open-source firmware transparency and user-controlled key isolation.

Its security profile reflects strong architectural isolation and auditability, balanced against operational complexity and user configuration risk.

Under the LISR v1 framework, Trezor receives a Tier B rating.

Risk Considerations

Operational security remains dependent on:

• Proper seed phrase handling
• Physical access controls

• Long-term cold storage
• Self-directed holders
• Users prioritizing firmware transparency
• Custody structures with defined operational procedures

Not Designed For

Less suitable for:

• High-frequency transactional activity
• Users unwilling to manage seed security
• Fully passive custody expectations
