I'm confused about 'contracts' in Ethereum. When do I need a 'contract'?
For the scope of my app: I want user to be able to generate ETH address, receive and send out ETHER and I should be able to get my wallet balance.
For this kind of scope, do I need a contract? Kindly explain to a noob.
What prompted me to ask this question is that I want to use blockcypher to create address, send wei and recieve. But I can't find a method where I can check the balance of the ETH wallet.
What am I missing?
