# Tennto

> Risk intelligence for exchanges and custodians evaluating AI-agent transfers before signing.

The external risk API supports Solana. Mode "fast" returns a completed assessment inline (HTTP 200); mode "default" starts asynchronous deep research (HTTP 202) with a cited report and final Jev score when evidence is sufficient. Tennto does not hold signing keys or return a binding Pass/Hold/Block verdict. Customers enforce their own policy. No result guarantees safety or regulatory compliance.
