A unique, non-interchangeable digital token representing ownership of a specific asset—artwork, collectibles, music, game items, domain names, or real-world assets. NFTs are verified on-chain and can be traded on marketplaces. Unlike fungible tokens (where each unit is identical), each NFT has distinct properties. Major Solana NFT marketplaces: Magic Eden, Tensor.

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.
Wallets, signing flows, dApps, and key management concepts.
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.

NFT (General Concept) (nft-general) Category: Web3 Definition: A unique, non-interchangeable digital token representing ownership of a specific asset—artwork, collectibles, music, game items, domain names, or real-world assets. NFTs are verified on-chain and can be traded on marketplaces. Unlike fungible tokens (where each unit is identical), each NFT has distinct properties. Major Solana NFT marketplaces: Magic Eden, Tensor. Aliases: Non-Fungible Token Related: NFT (Non-Fungible Token), Metaplex Token Metadata

Optional: paste Anchor, Solana, or Rust code so the Copilot can map primitives back to glossary terms.

These branches show which concepts this term touches directly and what sits one layer beyond them.
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.
The Metaplex Token Metadata program (metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s) that attaches rich metadata to any SPL token or NFT. It creates a PDA-derived metadata account storing: name, symbol, URI (pointing to off-chain JSON), creators array, seller fee basis points, and collection info. The de facto standard for NFT metadata on Solana.
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 decentralized exchange allowing peer-to-peer token trading without a centralized order book or custodian. Users trade directly from their wallets. DEXs use automated market makers (AMMs) or on-chain order books. Advantages: no KYC, self-custody, censorship-resistant. Disadvantages: potential for higher slippage, smart contract risk, and MEV extraction.
Distinction between services that hold users' private keys (custodial — exchanges like Coinbase) versus tools where users retain sole control of their keys (non-custodial — wallets like Phantom). Non-custodial means only the user can authorize transactions; custodial means trusting a third party with asset security.
Removing an NFT from sale on a marketplace by canceling its listing. Mass delistings during bull markets signal that holders expect prices to rise further and are unwilling to sell at current levels. Coordinated delistings reduce available supply on marketplaces and can push floor prices higher. Delist rates are tracked as a sentiment indicator for NFT collections.

The vision of a decentralized internet built on blockchain technology, where users own their data, identity, and digital assets. Web1 was read-only (static pages), Web2 is read-write (platforms like social media), Web3 is read-write-own (permissionless, user-sovereign). Web3 applications use wallets instead of logins and smart contracts instead of centralized servers.
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).
Software or hardware that manages cryptographic keys and enables users to sign transactions, view balances, and interact with dApps. Hot wallets (Phantom, Solflare, Backpack) are internet-connected for convenience. Cold wallets (Ledger, Trezor) store keys offline for security. Wallets don't actually 'hold' tokens—they hold the private keys that control on-chain accounts.
A 12 or 24-word human-readable backup of a wallet's master private key, generated using BIP-39 standard. The seed phrase can deterministically regenerate all derived keypairs (BIP-44 derivation paths). Losing the seed phrase means permanently losing access to all associated accounts. Never share, photograph, or store seed phrases digitally in plain text.
