ChipMixer easily has the best and longest standing reputation among all bitcoin mixers.

Wasabi now spy on their users and censor transactions, so I would no longer recommend them.

About 6 weeks ago, Wasabi announced on twitter that zkSNACKs, the entity which runs the coordinator for the all the coinjoin transaction which take place through Wasabi wallet, would start censoring some inputs and refusing to allow them to partake in coinjoins. Wasabi then explained on Telegram that they would be hiring a blockchain analysis company, which would monitor and surveil every user of Wasabi and ever UTXO stored on a Wasabi wallet and decide which ones were and were not allowed to partake in coinjoins. They have since revealed that they did this voluntarily to protect their own operations and therefore their own profits, and not because they were forced to because of any government, law, or regulation.

Wasabi is now pro-censorship and anti-privacy. They should be avoided, unless you like seeing your coinjoin fees go straight to a blockchain analysis company which is being paid to spy on you and you specifically.

A process which becomes much easier when the centralized coordinator is actively working with blockchain analysis companies and handing over all the data they collect.

No idea, and given how shady Wasabi have been about this whole thing, don't expect them to be honest and tell us. Any "privacy" firm coordinating with blockchain analysis firms is not to be trusted though, and especially not one which is actively using your coinjoin fees to pay blockchain analysis firms.

The situation map is currently thus:

- The Wasabi wallet itself is still clean and uncompromised.
- But the default CoinJoin server used by Wasabi wallet (zksnacks) is now blacklisting "tainted" coins, an action which is intolerable to the community.
- Ignore the signature campaign for now, it is irrelevant to remedying the situation.


This thread exists to gather open source software on Github/Gitlab/etc. which allows the running of a Wasabi-compatible CJ mixing server. Software that cannot be plugged in to Wasabi should not be listed here. Since this battle is being fought against their main CJ server, and not analysis companies/exchanges/governments, we still have a chance for winning this, even if we are 3 months behind schedule (the announcment for the blacklisting was made last march).

Discussion on how to make such CJ software work for Wasabi (as well as the other way around) is also welcomed. Special attention should be given to getting these to run on low-powered Linux servers (think 8GB of memory or less).

I also wouldn't recommend using Wasabi at all, even with a non censoring coordinator. The Wasabi devs have revealed very clearly where their priorities lie: Those priorities are not with their users or protecting privacy, but solely with making profits. Obviously Wasabi is open source, but I'm still not going to use a wallet which is run by a team who are willing to voluntarily sell out their users for profits.

It's not like Wasabi where they are sacrificing the privacy of the average user to cater to the bigger players.

Such an approach would require encouraging tens of thousands of people to download and use Wasabi and compromise their own privacy in doing so. Not a great approach.

There are plenty of other user friendly non full node wallets with such features. Granted, most don't provide coinjoins, but when you are also being spied on, censored, and having your addresses reused, then some might say a wallet without any of those features is better than Wasabi.

If you don't want to run a full node then I would suggest Sparrow wallet as the next best option to access coinjoins.

And if you depend on third parties, then you are subjected to their rules, spying, and censorship, as we have seen in the case of Wasabi.

By using Sparrow you are still depending on third parties, but at least those third parties aren't in cahoots with blockchain analysis companies. But if that is still too complex for the average user to use without compromising their privacy in some manner, then you can just stick to ChipMixer.

People who are using Wasabi aren't generally going to bother changing coordinator, because anyone who actually cares about privacy and not having their details fed directly to a blockchain analysis firm isn't using Wasabi in the first place.

It is a mistake for BTCPay to implement this. Even if someone manages to get enough volume on a coordinator which doesn't spy on users and directly fund blockchain analysis, then they are still risking address reuse and therefore complete failure of what they are trying to achieve by coinjoining in the first place.

Cool, so I can get blockchain analysis entities to specifically monitor the outputs in my hardware wallet now. Just what I've always wanted!

I regret ever suggesting that anyone should buy a Trezor, and I will never do so again. They have shown themselves to be anti-privacy and anti-fungibility, and are therefore not just selling out their users but are actively working against bitcoin itself, in order to line their own pockets.

As he says, however, if you already have a Trezor device (and no other hardware wallet you can swap to or can afford), you are probably safe to keep using it provided you don't go anywhere near the coinjoin feature. I also don't have a single shred of trust left for Trezor, though, so I would make sure you are using it through something like Electrum or Sparrow pointed at your own node and absolutely not relying on Trezor's servers. And when it comes to the time to upgrade or replace your hardware wallet, obviously do not buy another Trezor.

What the default coordinator does with the money it makes isn't important for the coinjoin user, but for the integrity of their business.

What's important here is to break down what's user's best courses to accomplish mixing. Even if funding blockchain surveillance is completely contradictory to being proclaimed a pro-privacy service, that doesn't change their coinjoin process. Just as if Samurai announced that they're funding the Ukrainian war, it wouldn't change the effectiveness of the coinjoin. It'd ruin their reputation, and people would stop using it; not because of effectiveness, but ethical concerns.
