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.

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.

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 field in Metaplex NFT metadata that specifies the creator royalty percentage on secondary sales, denominated in basis points (100 = 1%). For example, 500 means a 5% royalty split among the creators array according to their share percentages. Enforcement varies by marketplace—some honor royalties voluntarily, while programmable NFTs (pNFTs) enforce them at the protocol level.
A Token-2022 extension that stores token metadata (name, symbol, URI, and custom key-value pairs) directly on the mint account instead of requiring a separate Metaplex metadata account. Reduces account creation costs and simplifies token setup. The update authority can modify metadata fields after creation.

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.
