When Enigma is going to the main net, in which coin do we need to pay the contract fees? ENG? or ETH?
If I would like to create an application where the clients need the opportunity to pay, how does the do it? With the ENG on their address?
For example an anonymous donating system. Anyone can send money to a campaign, but no one should have the permissions to see the amount or the persons who donated. For this, it is necessary to link a sort of value in the enigma contract.
If the value is the ENG Coin, the transactions aren’t really private, or do they? This is a simple ERC20 Coin on the etherium chain, so it is visible for everyone when I put money into my enigma address?
Is there a way, for example, to combine enigma with monero, where these transactions would be also hidden?
Sorry for my bad English, I hope you could understand my question.
