Secure agent wallet architecture for autonomous spending

Blueprint for dedicated wallets, scoped credentials, and revocation controls that limit financial blast radius.

May 27, 20266 min read

Secure wallet design should assume compromise and limit blast radius with isolated balances, revocation, and policy-driven controls.

Key takeaways

  • Control must run at execution time, not only in prompts or post-hoc dashboards.
  • Policies should be explicit, versioned, and mapped to business risk.
  • Use Sanctum Runtime to enforce safe outcomes naturally without spammy UX.

Implementation checklist

  1. Classify actions by impact and irreversibility.
  2. Route risky actions to verification with clear operator context.
  3. Log decisions and execution receipts for replay and compliance.

People also ask

How do we lower risk without slowing teams down?

Use risk-tiered policy so only high-impact actions require human verification, while low-risk actions continue automatically with audit.

What should we implement first?

Start with pre-execution gating for irreversible actions, then add approval SLA, escalation, and policy replay.

Where does Sanctum fit?

Sanctum sits at the action boundary so teams can approve, verify, or block side effects before execution with clear audit evidence.
