My apologies for this late review, I briefly explained my problem to the manager.
I am surprised that when opening the official site, I get a MetaMask Phishing Detection warning. Tried on Chrome, Firefox and Brave it's the same everywhere.
https://metamask.github.io/phishing-warning/v1.2.1/#hostname=[banned mixer]&href=https%3A%2F%2F[banned mixer]%2F&newIssueUrl=https%3A%2F%2Fgithub.com%2Fmetamask%2Feth-phishing-detect%2Fissues%2Fnew
This page points me to
CryptoScamDB but I didn't find anything in that database about [banned mixer].
anyway, I ignored it and continued to the site.
To begin with, a very simple page. I support the simple and minimal design and [banned mixer] is certainly that. maybe even too simple, some info hints would be useful, just so that the user is informed in which part of the process he is.
I send 0.0022BTC, choosing the lowest fee of 0.5%. very quickly I received confirmation that the transaction was detected and after 1 hour
received exactly 0.00172645 BTC. Now I am not sure how is calculated 0.5% (of 0.0022)=0.00047355.
I saw in some discussion in this thread that there is a fixed fee of 0.0005 plus the service fee... but I can't calculate which fee is exactly included in my case.
before the transaction, I think there should definitely be some informative part here. For example, what amount can I expect after mixing and the expected time for the completion of the process.
also, why there is no temporary key or link here? in case I close the page, I can no longer return to the same page with the transaction process.
I downloaded the Letter of Guarantee, but there is not much information or confirmation in it, except for the address to which I should send the funds. For example, the address I set up with the receipt of the coin does not appear anywhere, and I have no proof of it. if something unplanned happens, it can be very complicated to further proof. certainly does not instil confidence in the security of the service.
About Privacy: however, I could hardly give a passing grade here. it is not difficult at all to track the entire transaction, because only two addresses were promised and practically the same coins that I sent were returned to me. (minus fees of course)
So, I send 0.0022 to
34WMBPP4GoQKNTVE4GeLLGrkBNTyJmwCgn after that, the amount was divided into two almost identical amounts and moved to 1Coj6kLgtmf8QHsjFkwVGTuhYqunAFP79g and 1F4rN4naRNGEwHnVq48sUhUmwt16uFPpvz
from there put together again to 3L96i8wTKAgE5h53ZtJZS64CimFRhdHc4z and finally to the final destination,
my receiving address.
honestly, this was very easy to follow. plus the separation into two identical halves and then rejoining it is almost obvious that it is coin mixing.
I would say that this is only a test phase, and my final impression is that there is still a lot of work to be done to finalize the product.
