### Store Updater ### Store Updater
The store updater can store, remove or update any arbitrary key value using the ERC725Y implementation (at the ERC721 level). The use case for this role depends a lot on what data is being stored in the ERC725Y key-value pair — as mentioned above, this is highly flexible.
