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.

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.

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 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.
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.

An SPL program that enables the creation of liquid staking pools on Solana. Operators create a pool, users deposit SOL and receive pool tokens (LSTs) representing their share. The program manages stake delegation across multiple validators, epoch-based reward distribution, and pool token pricing. Marinade, BlazeStake, and other liquid staking protocols are built on or inspired by the SPL Stake Pool program.
Data inscribed directly into on-chain Solana account data, inspired by Bitcoin Ordinals. Solana inscriptions store images, text, or other content as raw bytes in account data rather than pointing to off-chain storage. While more expensive than off-chain metadata (requiring rent for storage), inscriptions are fully on-chain and immutable once the account's update authority is revoked. They emerged as an experimental standard in late 2023.

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.
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.
