About This Project

Monban (門番 — Japanese for "gatekeeper") is a comprehensive, registry-based access control library for Sui Move. It solves the composability gap left by public, public(package), and public(friend) by letting you whitelist external packages at runtime via a dynamic AccessRegistry shared object. Callers prove their identity with a Witness derived from their own module types, enabling secure inter-package calls without hardcoding addresses or circular friend declarations. Published on Move Registry (MVR) for easy installation.

• •Dynamic AccessRegistry shared object for runtime package whitelisting
