Attarra
Coffee simplified
The problem Attarra solves
We pay you for buying coffee. We provide coins for every purchase and using those coins the customer can redeem points, get access to exclusive offers, and much more. This is a blockchain-based application that the Attarra peer group uses in order to circulate the contracts.
Challenges we ran into
We faced difficulty building a blockchain API to secure the app's storage.
