1. What Is NFT Metadata
NFT metadata is the structured data describing an NFT — its name, image, description, and attributes. It is what makes a token meaningful beyond its on-chain identifier.
2. How It Works
An NFT contract stores a tokenURI pointing to metadata (usually JSON). The metadata may live on centralized servers, IPFS, Arweave, or directly on-chain. Standards (ERC-721 metadata schema, OpenSea metadata) define fields so wallets and marketplaces render NFTs consistently. Storage immutability determines whether metadata can be changed.
3. Why It Matters
Metadata is the user-facing identity of an NFT — it determines what collectors see and value. Centralized metadata can be altered or removed (a rug-pull vector); on-chain or decentralized storage preserves authenticity. Metadata quality and permanence are core NFT diligence items.
4. Key Facts
- tokenURI → metadata JSON → image + attributes
- IPFS/Arweave hosting prevents unilateral changes
- Fully on-chain metadata is the most immutable
- Mutable metadata enables dynamic/game NFTs
