Metaplex Core Plugin
Token Ecosystem · Deep
An extensibility mechanism in the Metaplex Core NFT standard that attaches optional behaviors to assets or collections without requiring additional accounts. Plugins include Royalties (enforce creator fees), FreezeDelegate (lock transfers), BurnDelegate (authorize burn), TransferDelegate (authorize transfer), Attributes (key-value metadata), and AppData (program-writable data blobs). Plugins can be added at either the asset or collection level, and collection-level plugins apply as defaults to all members. Each plugin specifies its own authority and lifecycle rules, enabling modular composition of NFT functionality.
