I've been waiting for the new version to do a quick review, so let's go!
On the subject of aesthetics and the UI, I really like the fact that you've integrated a dark mode, it is always more than welcome.
Overall, I find the site beautiful, and very visually pleasing. I have nothing to say about that, everything is straight forward, intuitive. I think that having a simple navigation (especially compared to other more 'complex' mixers UI) is a safe bet, straight to the point. A lot of users prefer minimalist/simple interfaces.
At first, I tried to access Webmixer from Firefox with my usual VPN. But unfortunately I couldn't get past Cloudflare (I don't usually have this problem). I was stuck with CF loading again and again, same issue after deleting cookies or refreshing tab.
By changing servers I was also able to access the site with my VPN. Cloudflare isn't ideal in terms of privacy, but if I understand correctly, it seems difficult to find an equivalent as effective, so I understand. The vast majority of other mixers also use CF and not for nothing, so I guess we can't complain too much against CF usage..
No problem when using Tor, I can access the site. The site is very responsive overall, even the .onion is reactive, it's pleasant to use.
For the record, I use Firefox 121.0 on Debian and Android with Firefox Focus 119.0. I use the latest version of Tor browser.
I had already done a test with the "Basic" mixing mode and I was satisfied. The fee is low, and I had nothing in particular to say about it.
It's true that with "Precise" mode (which I used for my recent test) and "Max anonymity" mode the fee is 4 to 5 times higher, but personally, I'm not the kind of user who really wants to keep his fees as low as possible. For me, privacy comes at a price, and I'm ok to pay 5% if the service is reliable and efficient.
So I won't criticise you for the price of the service, but I do think that you could maybe increase the minimum deposit for 'Max' mode:
I reckon that 0.003 BTC minus (4-5% + 0.0007 BTC) can lead to unhappy begginer/new users, so why not set the minimum at 0.01 like for the "Precise" mode?
It's like with my coinjoin wallet, I know that below about 0.01, the operation isn't really profitable in any way.
Otherwise, I've tried to find the origin of the coins I've received back from the mixer, and I haven't been able to. I'm not a specialist in blockchain analysis, but I've tried several tools and explorers, and nothing has allowed me to trace my funds.
I've used several services and bots to try and check the origin of the funds (I know we shouldn't put too much trust in these services, but knowing that the big groups use them, I always find it interesting to see the results), everything seems to be fine. At least, nothing unusual:
Talking about your FAQ:
How many confirmations required? How to speed it up?
To start cleaning, your incoming transaction needs to have 1 confirmation by the network. Unfortunately we cannot speed up this process. Transactions with high fees and priority are usually confirmed in 5-20 minutes, and with very low ones - up to several days. You can wait for the transaction to be confirmed (it will not be removed from the mixer) or use a transaction accelerator (Google: "Transaction Accelerator").
I'm not sure it's wise to recommend this google search to novice users. When I do the search myself, the first result is ViaBTC so that's ok, but the others are all either scams or excessively expensive. The number of scams relating to transaction accelerators is huge. Maybe you could redirect your users directly to ViaBTC to avoid a potential scam? or tell them to "DYOR".
I like the fact that we can contact you on Jabber. SimpleX could be a good way to communicate with your users, maybe more popular?
Last suggestion: perhaps you could consider registering your service on
kycnot.me?
Next time, I will test your Telegram Bot (and give you a feedback on another platform)
