 In the examples below, we assume that you have an Alokai app with the Unified Data Model. However, the approach for non-unified Alokai applications is similar.

 These packages also provide tools for handling the global state management.

+The `SfContract` interface is used to define the contract between the SDK and the state management. It contains the types for:
+
+- cart (`SfCart` type)
+- customer (`SfCurrency` type)
+- currency (`SfCurrency` type)
+- locale (`SfLocale` type)
+
+This is needed to ensure that the state management is aware of the types that you have within the middleware, as those types can be changed within the middleware.

 This is also a place where you can import hooks for handling the state management. You can read more about the state management in the [State Management](/sdk/getting-started/state-management) page.
