Users download the Zappermint wallet app and import or create a new wallet. With this app installed on their mobile phones, they will be able to login with Zappermint from within another app. For example if you download your favorite game and they support Zappermint, you will be able to login and connect Zappermint with your favorite game. The ads, paywalls or subscriptions will be removed from your favorite game after login, when you stake enough USDN in the Zappermint smart contract. This amount is chosen by the developer and will vary from app to app.
