Plain meaning

Start with the shortest useful explanation before going deeper.

The lowest listed sale price for any NFT within a collection on marketplaces. Floor price serves as the baseline valuation for a collection and is the most commonly tracked metric for NFT market health. It fluctuates based on demand, new listings, and broader market conditions. Rarer traits within a collection typically trade at multiples above the floor. Tensor and Magic Eden display real-time floor prices for Solana collections.

Mental model

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.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

SPL assets, token standards, metadata, and NFT primitives.

Why builders care

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.

Concept graph

See the term as part of a network, not a dead-end definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

Branch

NFT (Non-Fungible Token)

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.

Mint Metaplex Token Metadata

Open term

Branch

Collection (NFT)

A Metaplex standard for grouping NFTs under a parent NFT that represents the collection. Each NFT's metadata includes a collection field with the collection mint address and a 'verified' flag (set by the collection authority via the Verify instruction). Collections enable marketplace grouping, royalty enforcement, and verification.

Tensor

A Solana NFT marketplace and trading protocol that launched the TNSR governance token in April 2024. Tensor provides advanced trading features including collection-level bidding, real-time price feeds, and lending against NFT collateral. It competes with Magic Eden as a primary NFT trading venue on Solana.

Freeze Authority

The pubkey authorized to freeze and thaw token accounts, preventing transfers. Set optionally at mint creation. When a token account is frozen, no transfers, burns, or closes can occur until thawed. Used for regulatory compliance (e.g., USDC) and security (freezing compromised accounts). Can be revoked by setting to None.

SPL Token Program

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 (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.

Token-2022 (Token Extensions)

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.

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.
