Hello

I need both android and ios developer to create an app with the following features:
1) Create a Trivia game that occure once per day. The game is time based.
2) Those who participate need to pay for a ticket. The entry ticket is paid via Ethereum. So the app should have the ability to get paid by Ethereum. The ticket should only work once. Each ticket should has its own hash.
3) Bot protection
4) Nice user interface (UI)
5) Fluid app motions
Something like that...

The accomplished job should be accurate and professional so please do not bid if you are not serious and has the right competence.
Otherwise, you are very welcome
