Cryptographic Security Architecture

Quantum resilience, deterministic wallet authorization and research into neural-inspired security intelligence.

Architecture and research notice. Standards and security engineering objectives described here must not be confused with deployed or independently certified defenses. No wallet can be guaranteed unhackable.

Neural-inspired security evidence network, not actual operational security telemetry — Conceptual neural security research illustration. AI observers cannot approve transactions.

01 / Quantum–Neural trust architecture

Four independent observation domains supply cryptographically authenticated evidence. Their outputs can raise risk alerts, but cannot grant transfer authority.

Identity evidencePrincipal, session and device

Wallet intentExact destination, amount and chain

Quantum readinessAlgorithms and migration risks

AI behaviorTool misuse and abnormal actions

Independent deterministic security policy

Security graph: signed evidence → independent policy → explicit signer approval → blockchain reconciliation. Research design, not a verified deployed NeuroShield service.

02 / Security engineering pillars

Quantum-resilient designFIPS 203 ML-KEM, FIPS 204 ML-DSA and FIPS 205 SLH-DSA, subject to protocol compatibility.

Wallet and address integrityBind network, contract, recipient, asset, amount, calldata, nonce and expiry to user intent.

EIP-7702 delegationDeny unknown delegated code, operators and capabilities; independently verify authorization.

Separated signingA compromised workstation, application or AI model must never independently authorize withdrawals.

SOVRA NeuroShieldResearch-only signed security observations with no signing or minting authority.

Verification and recoveryRecord security evidence, attack simulation outcomes, emergency controls and external assessment.

03 / Stop compromised signing requests

Private-key protection alone cannot prevent misuse of valid signing authority. Asset transfers require an independently enforced policy and a distinct signing trust boundary.

Untrusted workloadBrowser, developer machine or API

Signed intentAccount, network and exact transfer

Policy and limitsSeparate authorization and spend ceilings

Isolated signingHardware or threshold approval

Independent deterministic security policy

Mandatory design targets: default-deny unexpected EIP-7702 delegation, bounded exposure, anomaly containment and independent chain reconciliation.

04 / Post-quantum cryptographic migration

Migration is a verified engineering process, not a marketing label. Classical on-chain ECDSA or EdDSA signatures remain subject to their underlying cryptographic assumptions until the relevant chain or account protocol changes.

05 / SOVRA NeuroShield evidence graph

Proposed neuron-like observers compare independently signed events and surface suspicious behavior. All model output remains untrusted to the signing service.

Independent deterministic security policy

Signed sensor observations → research graph → deterministic authorization. No private keys, unrestricted credentials or transaction permissions enter the AI layer.

06 / Evidence and maturity

A release must be evaluated against its exact source commit and deployment. Architecture diagrams do not prove implementation, and a successful website build is not an independent security audit.

Review the machine-readable security control register. All twelve tracked live-control statuses remain unverified until supported by evidence.
