A Token-2022 extension that enables token grouping by pointing a mint to a group account or member account. The Group Pointer marks a mint as a group, and Member Pointer marks a mint as belonging to a group. Useful for NFT collections and hierarchical token relationships without requiring Metaplex.

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.
Use this compact block when you want to give an agent or assistant grounded context without dumping the entire page.
Group / Member Pointer (group-pointer) Category: Token Ecosystem Definition: A Token-2022 extension that enables token grouping by pointing a mint to a group account or member account. The Group Pointer marks a mint as a group, and Member Pointer marks a mint as belonging to a group. Useful for NFT collections and hierarchical token relationships without requiring Metaplex.

Use glossary context, relationships, mental models, and builder paths to get structured answers instead of generic chat output.
Optional: paste Anchor, Solana, or Rust code so the Copilot can map primitives back to glossary terms.
The Copilot will answer using the current term, related concepts, mental models, and the surrounding glossary graph.
These branches show which concepts this term touches directly and what sits one layer beyond them.
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.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.
These entries are easy to mix up when you are reading quickly, prompting an LLM, or onboarding into a new layer of Solana.
A Token-2022 extension that natively represents collections of tokens without requiring Metaplex. A mint with the Token Group extension acts as a collection, storing max_size and current_size. Mints with Token Group Member point to their group mint. This provides lightweight, protocol-level NFT collections directly in the token program.

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.

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.
