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.

Teams, protocols, tools, and the wider Solana product landscape.

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.

Branch

Lending Protocol

A DeFi protocol that enables users to deposit tokens to earn yield and borrow tokens against collateral. Key Solana lending protocols include Solend, MarginFi, Kamino, and Save (formerly Solend v2). Lending rates float based on utilization (borrowed/deposited). Deposits receive interest-bearing receipt tokens representing their share.

Branch

DeFi (Decentralized Finance)

Financial services built on blockchain smart contracts that operate without traditional intermediaries (banks, brokers). DeFi includes lending, borrowing, trading, insurance, and derivatives. Key properties: permissionless (anyone can participate), composable (protocols can be combined), transparent (open-source, auditable). Solana DeFi TVL has exceeded $5B, led by Jupiter, Raydium, Marinade, and Kamino.
