Rule Set (Authorization Rules)
Token Ecosystem · Abyss
A versioned on-chain account in the Metaplex Authorization Rules program that defines a tree of composable rules governing pNFT operations (transfer, delegate, burn). Rules include Allow, Deny, ProgramOwnedList (whitelist by program ID), PubkeyMatch, and AdditionalSigner, composed with All (AND), Any (OR), and Not operators. A rule set is referenced by a pNFT's metadata account and evaluated on every operation; if the rule tree evaluates to Deny, the transaction fails. Creators use rule sets to restrict transfers to approved marketplaces or enforce royalty payment.
