# AML transaction monitoring

AML transaction monitoring is the ongoing review of customer transactions to detect potential money laundering, terrorist financing, and other suspicious activity. Institutions run payments against risk rules and behavioral baselines, investigate the alerts those rules generate, and file suspicious activity reports (SARs) when warranted — a core pillar of a Bank Secrecy Act AML program.

In practice, monitoring means rules — velocity, thresholds, geography, structuring patterns — that fire alerts an analyst must disposition. False-positive rates run high across the industry, so the real cost is the investigation: for every escalated alert, someone gathers the counterparty file, transaction history, and supporting records, then documents a decision a regulator can examine.

Infinite monitors every transfer on the network, fiat and stablecoin alike, against the same program. Infinite Agents assemble and document each case before an analyst opens it — with every decision made by a human — so the alert queue turns into reviewed, defensible files instead of a backlog.

## Frequently asked questions

### What triggers a transaction monitoring alert?

Risk rules — velocity, thresholds, geography, structuring patterns — and deviations from a customer’s behavioral baseline. False-positive rates run high across the industry, so most alerts resolve after investigation. [Infinite Agents](https://infinite.net/compliance/ai)

### What happens after a monitoring alert fires?

An analyst investigates: gathering the counterparty file, transaction history, and supporting records, then documenting a decision a regulator can examine. If suspicion holds, the institution files a suspicious activity report. [Suspicious activity report (SAR)](https://infinite.net/learn/glossary/suspicious-activity-report.md)

### What is the difference between transaction monitoring and sanctions screening?

Sanctions screening is a point-in-time check of names against government sanctions lists, run before funds move — there is no suspicion threshold; a list match blocks the payment. Transaction monitoring is ongoing behavioral analysis that looks for suspicious patterns across transactions over time and can lead to a SAR filing.
