As far as I know, 0xMonero does not actually have any privacy features. 0xMonero's contract is a 99.999% percent code rip of 0xBitcoin's, and 0xBitcoin has no privacy features, so I don't know where any privacy features would be. Perhaps in some other contract, but I haven't seen anything like that specific to 0xMonero.

Here's a diff of the contracts of 0xBitcoin and 0xMonero that shows all the differences: https://i.imgur.com/c5cf0MJ.png
