Introducing the IIP related to package metadata.
Abstract
PackageMetadatais an immutable on-chain object that provides trusted metadata about Move packages during execution. BecausePackageMetadataobjects are created exclusively by the protocol during publish and upgrade operations, Move code can read this metadata with full confidence in its authenticity. This enables on-chain verification of package properties without relying on user-provided claims. This mechanism allows Move modules to introspect package capabilities, verify function signatures, and make decisions based on protocol-attested information.Discussion
