Role-Based Access Control (RBAC) with granular scopes
Enforced hardware-backed 2FA for all operators
Cryptographic Verification

Webhook & API Authenticity

Every outbound event and inbound request is validated through cryptographic signatures, preventing replay attacks, request tampering, and unauthorized callbacks.

HMAC-SHA256 signature on every webhook dispatch
Granular IP-allowlisting for production gateways
Timestamp tolerance headers preventing replay attacks
Continuous Compliance

Immutable Audit Trails

Every administrative action, balance adjustment, and API call creates a permanent, append-only audit record streamed to redundant SIEM monitoring nodes.

Write-once, tamper-evident transaction journals
