}Core Concepts
On-Chain Risk Enforcement
Risk checks execute inside the transaction, not via external API calls. Deterministic, zero-latency, un-bypassable.
Risk Tiers
Five levels: UNKNOWN, LOW, MEDIUM, HIGH, CRITICAL. Each tier triggers different enforcement actions.
Policy Engine
Configurable rules per asset: max transaction amount, daily limits, sanctioned address blocking, KYC requirements.
Quarantine Vault
Suspicious transfers are held in escrow until manual review or automated criteria are met.
