The convention for structuring NFT metadata established by Metaplex. On-chain: name (32 chars), symbol (10 chars), URI, creators, seller_fee_basis_points, collection. Off-chain JSON (at the URI): name, description, image, animation_url, external_url, attributes array [{trait_type, value}], and properties (files, category).

The Metaplex Token Metadata program (metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s) that attaches rich metadata to any SPL token or NFT. It creates a PDA-derived metadata account storing: name, symbol, URI (pointing to off-chain JSON), creators array, seller fee basis points, and collection info. The de facto standard for NFT metadata on Solana.
A non-fungible token on Solana—an SPL token with 0 decimals, supply of 1, and revoked mint authority. The NFT's metadata (image, attributes) is stored off-chain (Arweave/IPFS) linked via the Metaplex metadata account's URI field. NFTs can be standard, compressed (cNFT), programmable (pNFT), or Core assets, each with different trade-offs.
The JSON file referenced by an NFT's metadata URI that contains the full description, image URL, attributes, and properties. Typically stored on Arweave (permanent, ~$0.01), IPFS/Filecoin, or Shadow Drive. The JSON schema follows the Metaplex standard: name, description, image, animation_url, attributes[], properties{files[], category}.

The de facto standard for NFT metadata on Solana.
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 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.
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.
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.

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.
