And they also mention that they use CoinJoin and have temporary wallet functionally, which makes us more confusing whether it's classified as mixer or CoinJoin service.
FAQ Sudoku Wallet:
https://sudokuwallet.io/faqHow to mix my coins?You must add Bitcoins to your deposit address, wait for 3 confirmations then press "Mix my coins!". Using just 1 output address is not anonymous, so your coins will be split random between 2,3 or 4 addresses. You will receive clean coins, pre-mixed with CoinJoin, which haven't any connections with your deposit coins. Then you just should grab private keys, and import in your own main wallet.I went through the faq and i try out the process which i think it seems pretty easy to do even for a newbie but i would like to know if the generated wallet keys which were said to use to access the wallet and the deposit private keys, is it visible to your team? Can the private keys be used to import the deposit wallet address to wallet like electrum to be case?
