What is Nava Guardian?

Nava Guardian is Nava's deterministic policy evaluator. It reviews a proposed action against the active policy for that agent and returns a decision that an integrating builder can use before it acts.

The preview version of Nava Guardian is verdict-only and advisory. See Execution safety for the handoff from verdict to execution.

What Nava Guardian does

For each proposed action, Nava Guardian:

1. Decodes the action into the information needed for policy evaluation.
2. Resolves the active, per-agent policy.
3. Runs the deterministic checks that apply to that action and policy.
4. Stores and returns a versioned verdict.

The returned outcome is pending, approved, or rejected. A completed verdict includes reason codes and supporting evidence so an Agent Operator or builder can understand the decision.

Nava Guardian's deterministic approval path does not use an LLM. It is designed for repeatable policy evaluation, not for deciding whether an action matches free-form intent.

Developer Preview capabilities

The preview includes deterministic decoding and checks for Uniswap transactions, plus a versioned verdict shape. Verdicts are stored with database-backed metadata and returned to the integrating builder.

Policy authoring, the dashboard verdict workflow, and Hyperliquid action support are also Developer Preview surfaces. See Policy checks for the checks available in the preview and the check currently in review.

Where to go next

Agent Operators can start with the Agent Operator Guide to register an agent, configure a policy, and review verdicts. Builders should use the developer integration guide.
