Metaplex Core Collection
Token Ecosystem · Deep
A first-class collection entity in the Metaplex Core standard that acts as a parent for Core Assets. Unlike the legacy Token Metadata approach where collections were regular NFTs with a flag, Core Collections are purpose-built accounts that track size, enforce royalties, and manage plugins (freeze, burn, transfer delegates) at the collection level. Collection-wide operations like updating royalties propagate to all member assets automatically.
