How the Gramster advertising network works
Gramster is an advertising network within Telegram mini-apps.
You earn money for displaying ads in your mini-app. Currently, the rewarded format is used, which means the user must receive a bonus for watching an ad.
For example, in the Bcoin2048 game, the player receives a booster for watching a video ad.
More ad integration examples you can find here.

Payment occurs per 1000 impressions (CPM), which depends on the users' geolocation. For analytics and authorization in the system, you first need to register in the publisher's personal account.
