Daml finance app - Services as interfaces

Hi,
In the context of Daml finance app, would it make sense defining the services as interfaces?

Thanks!

Yes, indeed interfaces do make sense here a) to decouple client-side code or the UI from the Daml models, and b) to make upgrades easier.

There is a (WIP, non-functional) branch where we’re going exactly that, if you want to get an idea: GitHub - digital-asset/daml-finance-app at introduce-app-interfaces
