Most NFTs are known for representing something fixed: an image, collectible, membership token, or other digital asset whose defining characteristics remain largely unchanged after it is created. Dynamic NFTs take a different approach. They can evolve as circumstances change, allowing their appearance, metadata, attributes, or functionality to respond to new information.

NFTs are often associated with digital art and collectibles, but the same technology can also be used for something much more practical: membership. An NFT membership pass is a blockchain-based token that proves its holder has access to a particular community, service, event, platform, or set of benefits.
