Hardware-Level Resilience with Smart Card + Secret Share

Split the Key. Multiply the Security.

Smart Cards with CSTRNG: Randomness You Can Trust

Our smart cards are equipped with Cryptographically Secure True Random Number Generators (CSTRNG) — compliant with global standards such as FIPS 140-3 and Common Criteria EAL5+.

• Hardware-based entropy from physical noise sources
• Non-predictable and non-reproducible outputs
• Ideal for generating private keys, PINs, recovery seeds
• Immune to software-based RNG manipulation

Unlike pseudo-random software methods, CSTRNG ensures that each key is truly unique, non-reproducible and quantum-resistant.

Shamir’s Secret Sharing: Don’t Back Up — Divide

Instead of storing a key in one place, Shamir’s Secret Sharing Scheme (SSSS) divides it into multiple encrypted “shares.” Only a defined quorum is needed to reconstruct the original secret.

• e.g. Split into 5 shares, recoverable with any 3
• Each share is meaningless on its own
• No single point of failure
• Shares can be distributed across multiple cards, people, or locations

This enables decentralized key recovery, collaborative custody, and enhanced survivability in the event of loss, theft, or disaster.

Ideal for Wallets, DAOs & High-Security Environments

This model is perfect for:

• Hardware wallet backups without cloud dependency
• DAOs or treasuries requiring multi-party access control
• Enterprise-grade self-custody with tamper-proof hardware
• Emergency recovery kits distributed across geographic zones

It’s the gold standard for anyone who can't afford to lose — or expose — their private keys.

Integrated Security & Developer Options

• Compatible with JavaCard, NFC Smart Cards, and HSMs
• Native support for mTLS, PGP, ECDSA, and key wrapping
• APIs for secret splitting, verification, and secure reconstruction
• Can be combined with biometric MFA, stealth address, or secure enclave logic

Smart cards become not just secure storage — but active participants in secure computation.

‍Not all security is in the cloud. Some of it fits in your pocket — and belongs only to you.

With Smart Cards, CSTRNG, and Secret Sharing, you're protected by the physics of randomness and the logic of trust.
