Incognito Wallet and the Incognito App
As long as you are using the Privacy wallet or Incognito wallet you can use the Incognito Dex and swap coins for other coins. It doesn't matter what chain the coin is on because you are really only swapping pegged versions. I was able to get some pegged Monero, pegged Ether, and pegged BNB.
Now in order to send your coins to a different wallet, you need to do a process of unwrapping them and changing them from privacy coins back to the standard version of the coin. You can send the regular coin to an exchange or a wallet and use like before.
