block / review / clear before your agent signs.

Warden is the pre-execution security layer for agents transacting on Base. Give it a token, a pending transaction or an address — and collapse honeypots, unlimited allowances, sanctions, liquidity and holder concentration into a single decision. Decisions are deterministic; the LLM only explains them.

examples:

Deterministic decisions

The decision and risk score come from fixed rules. The LLM never touches the verdict — it only writes the plain-language rationale. Fully auditable.

Fails safe

If a security signal can't be fetched, it never returns a false 'clear' — it degrades to 'review' at worst.

Provable track record

Every verdict is snapshotted and its outcome re-measured. We show, in numbers, the rugs we flagged before they rugged.
