Deep Cold Storage Vaults & Optical Air-Gapped Settlement

Engineering permanently offline hardware vaults for multi-million dollar asset reserves with optical air-gapped data transfers.

Air-Gapped Optical Data Transmission

AssetHSM cold vaults communicate with external networks exclusively through animated QR codes or unidirectional laser diodes. Unsigned transactions are visually ingested, inspected on secure local displays, and signed without galvanic connection.

Deep Storage Redundancy and Disaster Recovery

Cold vault master seeds are geographically split into encrypted titanium backup shards using Shamir Secret Sharing, resistant to fire, submersion, and electromagnetic pulse (EMP) events.

Permanently Offline Hardware: Hardware security modules operating with zero network, wireless, or electrical connectivity.
Unidirectional Optical Handshake: Reading unsigned transaction hashes via high-resolution optical video capture.
Dual-Key Vault Access: Physical and biometric access control requiring dual-custodian physical presence in vault facilities.
Post-Quantum Vault Migration: Transitioning long-term cold reserves to lattice-based post-quantum key encodings.
