Hardware Security
Hardware wallets provide the highest level of security for cryptocurrency assets by keeping private keys isolated from potentially compromised computers and smartphones. Our team has deep expertise in building and securing these critical devices.
Our Hardware Wallet Experience
ZKNOX founders include the former CTO of Ledger, who led the development of the Ledger Nano—the world's best-selling hardware wallet. We bring this unparalleled experience to every hardware security project:
- Secure element integration and programming
- Side-channel resistant implementations
- Memory-optimized cryptographic algorithms
- Secure boot and firmware update mechanisms
Supported Platforms
We develop cryptographic implementations for leading hardware wallet platforms:
- Ledger — Nano S, Nano X, Stax
- Keystone — Air-gapped QR-based wallets
- Custom hardware — HSMs, secure enclaves, TEEs
4337 PQ Account & Kohaku
Our 4337 PQ account brings post-quantum smart accounts to Ethereum, integrated in Kohaku. FIPS 204-compliant signers ensure your assets remain secure even against future quantum threats.
Universal VM for Hardware Wallets
Our universal VM for hardware wallets provides fast integration in leading wallets (Ledger, Keystone, etc.). We implement FROST (Flexible Round-Optimized Schnorr Threshold) signatures for distributed key management across hardware devices.
Secure Your Hardware
