Security Architecture

Triple-Lock
Protocol.

Hardware NFT Key

A non-clonable cryptographic key tethered to the device. This Master NFT acts as root of trust, allowing you to authorize or revoke permissions for auxiliary wallets with hardware-level governance.

Removable EEPROM

The removable EEPROM hosts the NFT ID and acts as a physical lock. If a private key is compromised, trigger a Kill Switch — rendering stolen keys useless instantly.

MatrixChain Native

The firmware communicates directly with Enjin MatrixChain. Blockchain and cryptography validate signatures and ownership with zero intermediaries — pure trustless execution.

Security Model

Trustless
By Design.

The OCU Server is a courier — not an authority. It verifies your license and relays the signed payload. It cannot open a door. It cannot authorize access.

The entire chain of trust lives on the device: sr25519 signature verification, NFT ownership check via Enjin RPC, whitelist enforcement — all inside the C++ Core, behind the .so boundary.

Even if the OCU Server is compromised, shut down, or sold — no door opens.
This property holds as long as the integrator implements the Core correctly and does not introduce backdoors in the firmware.

Mobile Signing App

OCU
KeyStore.

OCU KeyStore is the dedicated signing wallet for the On-Chain-Unlock ecosystem. Authenticate with physical access points via QR code, NFC tag, or deep link — no browser, no third-party apps.

sr25519 signing — Substrate compatible
Multiple identities — independent key derivation
Biometric unlock — fingerprint & face ID
NFC tag reading — tap to authenticate
QR, NFC and Deep Link SID authentication support
Whitelist signature approval workflow (SID 10)
Enjin NFT portfolio — on-chain ownership display
Argon2 key derivation — encrypted local vault

Security Note: The private key never leaves the device. All signing operations happen locally in the Rust cryptographic layer. The server only receives the signature — never the key.
