Hello, I had a bad experience yesterday with solanamixer.com. Be careful, it's a scam!! First I had 2 Solana mixed, then 15 and another 2. All good so far. Then 26 and they were gone. Written several emails but no response. Written with a different email and pretending to be a new customer. I was replied to within an hour. so read your emails. The money is gone, I don't care, but watch out!
Solana is a blockchain with advanced smart contract functionality. You really shouldn’t need to use custodial mixers, when something similar to Tornado Cash or Railgun could be built on Solana. I have not found anything like that that is reputable and established. If you want privacy you would have to bridge to a different blockchain where you can anonymize your funds and then transfer them back to Solana.
