- We can't use a .onion url as we'll hand our neck to authorities and that's not in our plan now

What do you mean by this? Are you suggesting that the government is the one who controls the Tor network so they will record all of your activities?
- Cryptoyou runs on top of Yanda, the transparency protocol that proves every off-chain action and stores the logs on-chain.
How do we verify this? I'm not familiar with the tech you mentioned, but if what you said is true, then it should be possible to provide the data for each transaction after the user does the trade. Looks great, but will need more tests to see if it is easy to verify or not.
Btw, is the circle/swap symbol between the coin/token just a decoration? At first, I thought it will allows me to easily swap the coin I want to buy/sell but I can't click them at all. I also notice there is a withdrawal fee on the fee breakdown. What does this withdrawal refer to? I don't think it refers to an exchange withdrawal since you have a separate fee for that, at least for the ETH-BTC pair.
