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

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.
An NFT stored as a leaf in an on-chain Merkle tree via State Compression, reducing minting cost by ~1,000-5,000x. Only the tree root hash is stored on-chain; leaf data is indexed off-chain. A 1M cNFT collection costs ~50 SOL vs ~12,000 SOL for standard NFTs. Created via the Bubblegum program; transfers require Merkle proofs.
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.
An application with its backend logic running on a blockchain as smart contracts rather than centralized servers. dApps typically have a traditional web frontend that interacts with on-chain programs via RPC. Users authenticate with wallets instead of username/password. Examples: Uniswap (Ethereum DEX), Jupiter (Solana DEX), Magic Eden (NFT marketplace).
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.
A content monetization protocol on Solana where creators stake ACS tokens and subscribers lock tokens to access premium content, replacing traditional paywalls with a staking-based model. Subscribers maintain access as long as their tokens remain locked, earning staking yields while supporting creators. The protocol enables a non-extractive relationship between content producers and their audience.
A community management and identity verification tool on Solana enabling token-gated access, reputation scoring, and community analytics for DAOs and projects. Grape allows communities to set membership requirements based on token holdings, NFT ownership, or on-chain activity, creating verified community spaces with tiered access levels and contributor reputation tracking.
A DeFi protocol on Solana for minting USDH stablecoin against multi-asset collateral including SOL, BTC, ETH, and liquid staking tokens. Hubble pioneered the multi-collateral CDP (Collateralized Debt Position) model on Solana, allowing users to deposit diverse assets into a single vault to borrow USDH at low interest rates while maintaining exposure to their collateral.

The most popular Solana wallet, available as a browser extension and mobile app with multi-chain support (Solana, Ethereum, Polygon, Bitcoin). Phantom provides token swaps, NFT management, staking, and a built-in dApp browser. Known for its clean UX and rapid feature adoption, it has become the default entry point for most Solana users and consistently ranks among the top crypto wallets by active users.
A Solana-native wallet offering browser extension, mobile, and web interfaces with deep staking integration, hardware wallet support (Ledger), and a built-in dApp browser. Solflare was one of the first Solana wallets and provides advanced features like stake account management, token metadata display, and priority fee controls. It supports the Solana Wallet Standard for seamless dApp connectivity.
A multi-chain wallet developed by Coral (the team behind xNFT protocol) that combines MPC and self-custody models. Backpack pioneered executable NFTs (xNFTs) that embed full applications inside NFTs, enabling a decentralized app store experience within the wallet. It supports Solana, Ethereum, and other chains with a focus on developer extensibility and programmable wallet experiences.
A regulated cryptocurrency exchange built by the same team behind Backpack Wallet (Coral). Licensed in multiple jurisdictions, it offers spot and perpetual futures trading with a focus on the Solana ecosystem. Backpack Exchange integrates tightly with the Backpack Wallet for seamless fund transfers and aims to bridge the gap between centralized exchange liquidity and self-custodial wallet experiences.
