FAQ

Before you route.

What does approved capacity mean?

Approved capacity is the planned policy for providers that pass onboarding checks for model access and reliability. No provider capacity is connected yet.

What is actually verified?

This product preview illustrates routing and receipt metadata. No inference route is live yet; spend controls and settlement receipts remain planned. AI output correctness is never verified.

Do I need a project token?

The current console preview needs no token because it sends no inference traffic. API authentication and project credentials arrive with the gateway vertical slice.

Are prompts stored on-chain?

No. The architecture keeps prompts and model responses off-chain. Planned receipts contain only the minimum routing and settlement metadata needed for an audit trail.

Who can become a provider?

The provider market is planned and applications are not open yet. The onboarding policy will review model access and reliability before any capacity can receive traffic.

Is this affiliated with Robinhood?

No. Proofrail is an independent project designed for Robinhood Chain testnet. It is not affiliated with or endorsed by Robinhood Markets, Inc.
