OFAC Transaction Monitoring

Transaction monitoring is the ongoing review of payments for sanctions compliance, including patterns that hint at evasion.

TL;DR

TL;DR: OFAC transaction monitoring is the continuous review of transactions for sanctions compliance, including pattern analysis that can reveal attempts to evade screening.

What it means

Monitoring is the ongoing layer that sits behind point in time screening. Where a single screen checks one counterparty before a payment, monitoring watches the stream of transactions over time and looks for patterns, such as structuring payments to stay under a threshold or routing through multiple intermediaries to hide a connection.

Why it matters for agent payments

An AI agent can make many small payments quickly, so evasion patterns are easy to hide in volume. Screening each one against 19,218 SDN names and 947 OFAC-listed crypto wallets, synced hourly, keeps the individual check accurate, while monitoring catches the behavior that only becomes visible across many checks.

How it fits the flow

Screening and monitoring work together. SanctionsAI runs the SCREEN step as a single HTTP call under 100 ms, returning ALLOW or BLOCK. Monitoring adds the second look that flags a sequence of payments a single clean screen would miss, closing the gap between a one off check and a real compliance program. It is the difference between catching one bad payment and catching the pattern that reveals a bad actor trying to stay under the radar. A single clean screen will not spot structuring, but a stream of small payments will.
