Challenge app

I want to make an app were I can login with fb twitter or instagram. And I know can choose between 4 challenges, 5-10-20-50$. Once I pay the challenge with crypto like Bitcoin and Litecoin I will now have it on the escrow. I can now share the link or send it to a friend and once he pays the challenge payment. One wins the other loses and the fees goes to the project. And i want this challenge app to work on all games.
