DOCUMENTATION

Build a bounded
private permission.

Documentation for protocol teams and capability holders. Each topic opens as a proper web page.

Protocol overview

What an issuer, policy, pass holder, and Gatekeeper each do.

Integrate a target

Protect one narrow protocol operation behind the Gatekeeper.

Use a capability

What a holder sees and confirms in the app and wallet.

Privacy model

What stays public, what the private note protects, and why relay matters.

Security

Contract invariants, tests, and the verified Mainnet issuance and exercise.

My capabilities

Connect a compatible wallet and see its available permissions.

Direct integration

Protocol developers integrate BlackBox through Cairo interfaces and the capability SDK. The core protocol does not depend on an invented hosted REST API.
