Some questions to start buidling

[Shelpin]

Shall we use testnet for production ?

Given that tokens generated are a representation of value of euros to be paid by the brand, and there are many transactions involved for the ,deployment of contracts, issuance, transfer, validation and so on, I was thinking in building a first version under testnet… do you see it a good solution to avoid spending too much in gas?

Knowing who is the issuer of the token / has the "liability" to donate

Tokens are issued by brands regarding a percentage of the sale made… I think is convenient to keep the amount of smart contracts and their interaction as low as possible (even working in testnet), first do you agree… ?and second would it be possible that tokens are labeled with the issuing brand, using only one smart contract for the issuance of tokens corresponding each purchase

What is the best way to extract the data of the “sale” in the checkout of any associated brand web page, and assign and issue the tokens to the customer tokens… (if possible not through oraclize / additional costs/parties)
