Agent Guardrails in Production

Running agents with real financial authority proves guardrails aren't optional. They're the difference between a useful tool and an expensive mistake.

Start with simple limits. Maximum transaction size, daily spending caps, approved token lists. Basic stuff but it catches near-disasters. Agents have tried to swap entire portfolios due to parsing errors.

Then add more sophisticated checks. Anomaly detection on transaction patterns. Comparison against expected behavior. Circuit breakers that pause everything if something looks weird.

The tricky part is balancing safety with autonomy. Too many restrictions and the agent can't do its job. Too few and you're one bug away from disaster. Finding the sweet spot takes iteration.

Shadow mode for new strategies is essential. The agent proposes transactions but doesn't execute. Review for a week before enabling real execution. Catches most issues before they cost money.

Multi-sig for large transactions is critical. Agent proposes, human confirms anything above threshold. Adds friction but the peace of mind is worth it.

The ecosystem needs better tooling here. Everyone's building custom guardrail systems. We should have battle-tested frameworks by now.
