Overview
A metadata standard is a spec for how NFT metadata is structured, such as the ERC-721 metadata extension. It ensures interoperability. Standards define fields like name, image, and attributes.
How It Works
A contract returns metadata via a URI, typically JSON following a standard schema. Wallets and marketplaces read it to display NFTs. Standards make data portable.
Why It Matters
Metadata standards enable consistent NFT display and tooling. They are essential for interoperability. Deviations can break compatibility.
