+## Customize Marketplace
+Create a customized user experience using the `naddr` from [NIP-19](https://github.com/nostr-protocol/nips/blob/master/19.md#shareable-identifiers-with-extra-metadata). The use of `naddr` enables easy sharing of marketplace events while incorporating a rich set of metadata. This metadata can include relays, merchant profiles, and more. Subsequently, it allows merchants to be grouped into a market, empowering the market creator to configure the marketplace's user interface and user experience, and share that marketplace. This customization can encompass elements such as market name, description, logo, banner, themes, and even color schemes, offering a tailored and unique marketplace experience.
