What is an Agent Audit Trail?

1 min read Updated

A chronological record of every financial decision, transaction attempt, policy evaluation, and approval/denial — complete accountability for agent spending.

WHY IT MATTERS

As agents handle more financial activity, tracing what happened, when, why, and who authorized becomes critical for compliance, debugging, and disputes.

Captures: transaction request, policy evaluation, decision, and outcome. Complete evidence chain.

Beyond compliance, trails help understand behavior, optimize policies, detect anomalies, and improve performance.

HOW POLICYLAYER USES THIS

PolicyLayer maintains immutable trails of every decision — every evaluation, approval, denial logged with timestamps and cryptographic proofs.
