WAX NFT Schemas: Define Your NFT Data
Schemas are the data structure behind every WAX NFT — they define which fields and attributes your NFTs can have.
A schema is a data structure that defines what fields and attributes your NFTs can have. Every NFT minted on WAX belongs to a schema.
Common fields include name (string), img (ipfs image hash), video (ipfs), and rarity (string). Available data types include string, image/ipfs, integer types (uint8–uint64, int8–int64), float/double, and bool.

Schemas are append-only
Once a schema exists on-chain, existing fields cannot be deleted and their data types cannot be changed. You can, however, append new fields at any time to expand your metadata format.
