A Token-2022 extension that protects token accounts from certain actions during CPI. When enabled, it blocks approve, close, and transfer operations via CPI while still allowing them in top-level instructions. This prevents malicious programs from draining or closing token accounts during composable calls.

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 mechanism for one program to call another program's instructions during execution. CPIs enable composability—e.g., a DeFi program can call the Token Program to transfer tokens. CPI depth is limited to 4 levels. The caller passes accounts and instruction data, and the callee runs with the same transaction context.

A Metaplex program that wraps Candy Machine with configurable access control guards for NFT minting. Guards include allowlist (Merkle proof), mint limit (per wallet), start/end date, sol payment, token payment, NFT gate, freeze (lock minted NFTs), and more. Multiple guards can be combined and organized into groups, allowing different mint phases (e.g., allowlist phase, then public mint) within a single launch.

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.
