Import the seed and set the derivation path of bad bank.
Next release will make wallet import better.
Discussion
Thanks for the info. I did not know that this is possible.
Is there a way to combine multiple Wasabi Wallets for Coinjoining or add a seed to an existing wallet? This way one could mix a bad bank wallet with a greater anonymity set. For example adding a Samourai Wallet to an existing (already mixed) wallet and using "red coin isolation".
Unfortunately not...
You should set "red coin isolation" to true, and you'll have private coins in the wallet for more ambiguity after the first round.
Next release will also have coinjoin to other wallet, so you can make a 1 input 2 output coinjoin from bad bank to other wallet with existing funds.
This is good enough for me.
I think the use case of mixing a third party wallet without first transferring to a new Wasabi wallet is a big one. Especially when fees are high and there are many small UTXOs. Transferring would correlate the UTXOs which will greatly reduce backwards privacy before mixing.
Thank you for working on bitcoin fungibility. Wasabi is an amazing wallet.
Yes, exactly, Bitcoin privacy is pretty great, if you make every transaction a large coinjoin.
Glad that you like Wasabi! 💚
