Wallet screening is a distinct AML/CFT control that assesses risk at the address level, separate from transaction monitoring. Effective programs combine risk-based KYC, sanctions checks, real-time screening, indirect exposure detection, and continuous cross-chain monitoring into a layered, auditable control set. Regulatory expectations from FATF, OFAC, EU, and HM Treasury require defensible documentation, timely escalation, and adaptive policies. Success is measured through concrete KPIs like alert rates, true-positive rate, time to disposition, and SAR effectiveness. Key components include adopting a risk-based approach with tiered controls, integrating with KYC processes, screening for indirect exposure, conducting real-time and continuous cross-chain screening, maintaining auditable documentation with clear escalation paths, and testing and tuning screening rules regularly.

Key facts

• Wallet screening assesses address-level risk at onboarding and ongoing, distinct from transaction monitoring.
• Regulators (FATF, OFAC, EU, HM Treasury) demand documented, risk-based screening programs.
• Effective programs integrate KYC, sanctions checks, and indirect exposure detection across chains.
• KPIs include alert rate, true-positive rate, time to disposition, and SAR effectiveness.
• Continuous monitoring and periodic rescreening adapt to evolving risk and designations.
