Security Model
Radio-free personal HSM and Bitcoin signing device that encrypts seed phrases into AES-256-GCM cryptograms, enforces optional biometric physical-presence controls, exchanges only encrypted files through a deterministic USB-C mounted-storage bridge, signs double-air-gapped PSBTs, and never stores private keys after operations complete.
Trust Assumptions
- Users verify Cuvex BIT firmware, software, and hardware sources or trust official distribution
- AES-256-GCM encryption and cryptogram handling are implemented correctly
- The USB-C file-bridge parser rejects malformed or unexpected files as documented
- Fingerprint enrollment and matching correctly enforce biometric cryptogram access control
- Users safely manage passwords, encrypted cryptograms, and any biometric/shared-custody rules
- Users understand Cuvex BIT is a pre-order/new product with limited long-term public review history

Known Issues
2026: Pre-order and maturity risk
Cuvex BIT was marketed as a pre-order device with delivery timing around late 2025, so buyers should verify current shipping status and public review history before treating it as a mature product.
2026: Biometric cryptogram lock-in
Cuvex states biometric-protected cryptograms require Cuvex BIT and cannot be decrypted by the desktop app alone, adding stronger physical presence but also device-specific recovery dependency.
