How we protect your keys.
VKX Wallet is non-custodial: your recovery phrase stays encrypted on your device. Below is the technical model published in the Security Architecture v1.0 specification.
Design principle
"The security layer is incremental: it adds post-quantum readiness and device integrity checks without changing the protocols of supported blockchains or the standard BIP-39 derivation flow."
Post-quantum readiness layer
Beyond the elliptic curves used by the networks, VKX generates an ML-DSA-65 (Dilithium3) key pair — the algorithm selected by NIST for post-quantum standardization. Generation happens locally on the device; the public key may be registered on the backend only to verify proofs.
Off-chain hybrid signing
When you approve a transaction, the device produces the ECDSA/Ed25519 signature the network requires and, in parallel, an ML-DSA signature of the payload. The result is an authorship proof carrying the transaction hash, the quantum signature and the device identifier — an audit trail independent of the network.
Quantum Shield and device integrity
An integrity score evaluates root/jailbreak, emulators, debuggers and Secure Enclave/TEE availability. Below the defined threshold, critical features are blocked. Quantum Shield is the subscription layer that enables mandatory gating, a persistent proof registry and encrypted backup of the post-quantum key.
