Think creative solution 2. Implement and integrate with existing app 3. Production level coding 4. Knowledge sharing with me during this entire process It also involves knowledge on crypto esp. Ethereum network. because i am planning on using crypto for in app purchases. However, first thing first, gotto implement and work on the IOS feature first.
