The set of optional features available in Solana's Token-2022 program, each activated per-mint or per-account. Extensions include transfer fees, confidential transfers, transfer hooks, permanent delegate, non-transferable tokens, interest-bearing tokens, default account state, memo required, metadata pointer, group pointer, and CPI guard. Extensions compose — a single mint can enable multiple features simultaneously.

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.
Token-2022 Extensions (token-2022-extensions-list) Category: Token Ecosystem Definition: The set of optional features available in Solana's Token-2022 program, each activated per-mint or per-account. Extensions include transfer fees, confidential transfers, transfer hooks, permanent delegate, non-transferable tokens, interest-bearing tokens, default account state, memo required, metadata pointer, group pointer, and CPI guard. Extensions compose — a single mint can enable multiple features simultaneously.

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.
A Token-2022 extension that invokes a custom program on every token transfer. The hook program receives the transfer details and can enforce additional logic (royalties, compliance checks, transfer restrictions). The hook program address is set on the mint. Hooks execute via CPI and must conform to the Transfer Hook Interface.
A Token-2022 extension that uses zero-knowledge proofs (Twisted ElGamal encryption over Ristretto255) to hide transfer amounts while keeping the token mint and accounts public. Balances are stored in encrypted form with separate 'pending' and 'available' pools. The account owner can decrypt their balance but others cannot see amounts.
A Token-2022 extension that automatically withholds a percentage of every transfer as a fee. The fee (basis points + max fee) is configured on the mint by the transfer fee authority. Withheld fees accumulate in recipient token accounts and can be harvested by the withdraw authority. Enables on-chain royalties for fungible tokens.
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.
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.
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.
A deterministically derived token account for a given wallet and mint, using the PDA seeds [wallet, token_program, mint]. ATAs provide a canonical address so anyone can send tokens to a wallet without the recipient creating an account first. The ATA program creates the account on first use, funded by the sender.

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.
