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.

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.

SPL Stake Pool (stake-pool-spl) Category: Token Ecosystem Definition: 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.

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.
A mechanism where staked SOL is represented by a transferable token (LST) that accrues staking rewards while remaining usable in DeFi. Instead of locking SOL with a validator, users deposit into a liquid staking pool and receive tokens like mSOL (Marinade), jitoSOL (Jito), or bSOL (BlazeStake). LSTs typically appreciate against SOL at the staking APY.
A dedicated on-chain account that holds delegated SOL for staking. Each stake account has a staker authority (can redelegate) and a withdrawer authority (can withdraw). A stake account can only delegate to one validator at a time, so users create multiple stake accounts to split across validators.
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.
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.

An SPL program that implements a constant-product AMM (x*y=k) for swapping between two SPL tokens. It was one of the first DeFi primitives on Solana but has been largely superseded by more sophisticated DEXs like Raydium, Orca, and Meteora. The program manages liquidity pools and issues LP tokens to liquidity providers.

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.
