A Metaplex program that defines and evaluates rule sets for programmable NFTs. Rules specify conditions for transfer, delegate, and other operations—e.g., allow transfers only through specific marketplaces (by program ID), require payment of royalties, or restrict to certain collections. Rules are composable using AND/OR/NOT logic.

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.
Think of it as a building block that connects one definition to the larger Solana system around it.
Place the term inside its Solana layer so the definition is easier to reason about.
SPL assets, token standards, metadata, and NFT primitives.
Turn the term from vocabulary into something operational for product and engineering work.
This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

Authorization Rules (authorization-rules) Category: Token Ecosystem Definition: A Metaplex program that defines and evaluates rule sets for programmable NFTs. Rules specify conditions for transfer, delegate, and other operations—e.g., allow transfers only through specific marketplaces (by program ID), require payment of royalties, or restrict to certain collections. Rules are composable using AND/OR/NOT logic. Related: Programmable NFT (pNFT), Metaplex Token Metadata

Optional: paste Anchor, Solana, or Rust code so the Copilot can map primitives back to glossary terms.

These branches show which concepts this term touches directly and what sits one layer beyond them.
A Metaplex NFT type (pNFT) that enforces creator-defined rules on transfers using an on-chain authorization rules engine. pNFTs always require the token record (state PDA) and must go through the Metaplex program for transfers, enabling royalty enforcement. Transfer rules are defined in a RuleSet account that can allow/deny based on program IDs, collections, or custom logic.
The Metaplex Token Metadata program (metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s) that attaches rich metadata to any SPL token or NFT. It creates a PDA-derived metadata account storing: name, symbol, URI (pointing to off-chain JSON), creators array, seller fee basis points, and collection info. The de facto standard for NFT metadata on Solana.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.

The original Solana Program Library token program (TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA) that implements fungible and non-fungible token operations. It manages mints (token definitions) and token accounts (balances). Core instructions include InitializeMint, MintTo, Transfer, Burn, Approve (delegation), and Revoke. All SPL tokens on mainnet before Token-2022 use this program.
Solana Program Library—a collection of on-chain programs and client libraries maintained by Solana Labs. Key SPL programs include Token, Token-2022, Associated Token Account, Memo, Name Service, Stake Pool, and Account Compression. SPL programs are deployed to well-known addresses and serve as the standard building blocks for Solana applications.
The next-generation token program (TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb) that extends SPL Token with configurable extensions. Extensions include transfer fees, confidential transfers, transfer hooks, permanent delegate, non-transferable tokens, interest-bearing tokens, metadata, and more. Token-2022 is backwards-compatible with SPL Token for basic operations.
An on-chain account defining a token type. A mint specifies: supply (total minted), decimals (0 for NFTs, 6 for USDC, 9 for most tokens), mint authority (who can mint), and optional freeze authority. Each unique token (USDC, JitoSOL, etc.) has exactly one mint account. Mint address serves as the token's unique identifier.
