Token-2022 Extensions

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.

Token-2022 (Extensiones de Token)

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.

Transfer Hook

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.

Transferencias Confidenciales

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.

Transfer Fee Extension

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.

Programa SPL Token

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.

Cuenta de Token

An account that holds a balance of a specific token for a specific owner. Token accounts store: mint (which token), owner (who controls it), amount (balance), delegate (optional), and state (initialized/frozen). Each wallet needs a separate token account per token type. Token accounts require ~165 bytes and rent-exempt minimum of ~0.002 SOL.

Solana Program Library (SPL)

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.

Mint

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.
