Overview
NFT metadata is the data describing an NFT, such as its name, image, and attributes, often stored off-chain. It defines what the NFT represents. Metadata is linked from the token contract.
How It Works
The contract stores a URI pointing to metadata, typically in JSON, hosted on IPFS or a server. The metadata includes image and trait fields. It can be updated if the contract allows.
Why It Matters
Metadata determines the visual and descriptive identity of an NFT. Off-chain storage creates persistence risks. Understanding metadata is key to NFT utility and evaluation.
