What is Transaction Monitoring?
Transaction monitoring is the ongoing surveillance of cryptocurrency transactions to detect suspicious patterns, policy violations, and anomalous behavior — enabling real-time alerts and automated responses to potential threats.
WHY IT MATTERS
Prevention is better than detection, but detection catches what prevention misses. Transaction monitoring provides visibility into what agents are actually doing — revealing patterns that policy rules alone might not catch.
Monitoring systems track metrics like transaction velocity (sudden spikes in frequency), unusual recipients (new addresses not in the allowlist), amount anomalies (transactions just below policy limits), gas anomalies (unusual gas patterns suggesting contract exploitation), and behavioral changes (agent deviating from established patterns).
For agent operators, monitoring is the feedback loop. It validates that policies are working correctly, identifies policy gaps (agents finding workarounds), and provides early warning of compromises before catastrophic loss.
HOW POLICYLAYER USES THIS
PolicyLayer provides real-time transaction monitoring for all agent activity — tracking spending patterns, flagging anomalies, and maintaining complete audit trails. Monitoring data feeds into policy refinement and incident response.
