We’ve read Wasabi wallet shouldn't be used because they're using blockchain analysis companies https://bitcointalk.org/index.php?topic=5286821.msg62421785#msg62421785. I don't know everything about their relationship so I'm asking questions about info they're storing or sharing.
Wasabi does not store or share any data with blockchain analysis companies. Your client never shares your xpub address with any third parties, including the coordinator, since it uses BIP158 compact block filters. Your client never shares your IP address with any third parties, including the coordinator, since it uses Tor.
Here's some fun code from Wasabi (https://github.com/zkSNACKs/WalletWasabi/blob/795496595fae2f52730e1556bb6cafd2c649bb97/WalletWasabi.Tests/UnitTests/WabiSabi/Backend/CoinVerifierTests.cs#L133-L142):
Are your coins "naughty"? Once Wasabi have spied on them and made that decision, then you will be banned from coinjoining them with Wasabi.
Add in the fact that they suffer from endemic address reuse (https://bitcointalk.org/index.php?topic=5419000.msg61220171#msg61220171, https://bitcointalk.org/index.php?topic=5286821.msg62085316#msg62085316), and I would steer well clear of ever using Wasabi.
Code:
ScheduleVerifications(coinVerifier, generatedCoins);
foreach (var item in await coinVerifier.VerifyCoinsAsync(generatedCoins, CancellationToken.None))
{
if (item.ShouldBan)
{
naughtyCoins.Add(item.Coin);
}
}
Assert.Empty(naughtyCoins); // Empty, so we won't kick out anyone from the CJ round.
foreach (var item in await coinVerifier.VerifyCoinsAsync(generatedCoins, CancellationToken.None))
{
if (item.ShouldBan)
{
naughtyCoins.Add(item.Coin);
}
}
Assert.Empty(naughtyCoins); // Empty, so we won't kick out anyone from the CJ round.

Hmm, sounds interesting
