Revise

Revise is a metadata protocol for dynamic NFTs, offering developers an SDK and authenticated endpoints to host, read and rewrite the metadata fields of a token. The mechanism-level problem it targets is that ERC-721 metadata written to IPFS cannot be changed, while use cases such as game items, tickets and membership passes need state to evolve; most projects end up hosting metadata on centralized servers, which sacrifices the decentralization property.

After integration, a developer creates a collection and token entries, writes parameters such as image location, name, description and traits, and can then update them field by field as business logic requires, so the appearance or attributes of one NFT change over time. The protocol is discussed as part of the dynamic NFT and programmable metadata layer of NFT infrastructure. It differs from generative art projects in that it governs update rights and storage structure at the metadata layer rather than on-chain image composition rules.
