Store Listing Fields

When you register an app, you provide metadata that appears in the app store:

​
NFT Metadata Standard

App tokens and in-app items follow ERC-721 with ERC-4906 metadata update signaling. This means metadata changes emit on-chain events that marketplaces can listen to for auto-refresh. Example metadata JSON:

​
Image Requirements

Use square images for logos and token images. Non-square images will be cropped in the store.

​
Storage Options

Once metadata is referenced on-chain, changing the underlying content at the same URI does not trigger an ERC-4906 update. Use setTokenURI to point to new content and emit the update event.

​
Updating Metadata

After launch, your Safe can update app metadata by calling the appropriate registry function. Token metadata updates follow the ERC-4906 pattern: set a new URI and emit the MetadataUpdate event so marketplaces and indexers refresh.
