    SMART CONTRACTS Looking to write these use cases, and then (maybe) develop them. Need to write use cases for the following: Smart Contract as Title: I imagine tradeable token(s), that are linked or? One token will show the state of all the fractional title holders within the whole of a titled object, and other tokens will represent fractional ownership of the whole (I’m open to ideas on how to do this). I have questions about how much data I can or should store on-chain. I imagine an excel-like spread sheet shows all relevant data- which may be on or off chain with a decryption key provided if off chain. Smart Contract to Create Crypto Currency: Create a Crypto Currency that admin sets quantity in circulation—Presumably an ERC-20 Token Smart Contract as Title and ...

    Hi. I need to add a new SDK to a couple of Apps I have for iOS and Android. I think it's probably a pretty simply SDK that generates a payment toke...credit card - if I could get that token and pass it to a function in my API then I can handle the rest on the API side - and maybe return a success value like 1 to whatever you install, so we can show a success page. Ideally, I think I'd like to use their sample apps to just emulate what I need without even trying to put it in my apps yet. Basically their new SDK should mainly product payment tokens for each credit card submitted and I need those so I can pass them into my API functions that combine the payment token AND the Order ID to pay for specific orders.
