Everything actionable you need to know about what this indictment means for you as a Samourai Wallet (SW) or Whirlpool user π
As a Samourai Wallet user (no Dojo)
Unfortunately, the architecture of SW meant that your xpub (a master public key, allowing anyone holding it to derive all your past/present/future Bitcoin addresses) was at some point in time held by Samourai, and could now possible in the hands of the DOJ.
Though it's a worst-case scenario, you should assume that your xpub was compromised, and thus all previous mixes you have done have been unwound and are now traceable. You should also assume that the gov can now derive all past/present/future addresses of yours and track movement of funds if so desired.
In addition, Samourai's coordinator and backend sync server was seized, and so SW will no longer sync, show received funds, or allow sending funds out. As such, you have to migrate funds to another wallet like @SparrowWallet following the docs here:
https://docs.samourai.io/wallet/restore-recovery#export-to-external-wallet
In addition, I would recommend migrating funds to a new seed phrase to prevent anyone holding the xpub from seeing all future received/spent funds.
You should also disable automatic updates in the Play Store (if used) to ensure no malicious updates are pushed.
As a Samourai Wallet user (using your own Dojo)
Thankfully, you avoided having your xpub potentially compromised. The worst case scenario for you is that your previous mixes may not have the full anon set you expected if non-Dojo users xpubs were compromised.
You will still be able to sync/send/receive from your Samourai Wallet app, but should also migrate funds eventually as no further updates will come out for Samourai Wallet. If you want to migrate, use the docs below:
https://docs.samourai.io/wallet/restore-recovery#export-to-external-wallet
You should, however, disable automatic updates in the Play Store (if used) to ensure no malicious updates are pushed.
As a Sparrow Wallet user
Thankfully, you avoided having your xpub potentially compromised as well. The worst case scenario for you is that your previous mixes may not have the full anon set you expected if non-Dojo/Sparrow users xpubs were compromised.
There is no real need to rotate to a new wallet etc, and Sparrow is still an excellent option. Unfortunately you will no longer be able to mix in Sparrow as the Samourai coordinator was seized.
Next steps for privacy
If you (like me) relied on Samourai Wallet for privacy on Bitcoin, it's time to look elsewhere sadly. As of today I have two recommendations:
Use Monero for spending, keep using Bitcoin for savings
Yes, this isn't Bitcoin, but its by far the most used and most practical privacy coin out there with strong (and growing) ways to swap in/out of it without a centralized, KYC exchange. My recommendation is buying enough to cover your normal spending of Bitcoin for a month at least, and spend out of that lump sum as needed.

Merchants that accept Monero:

Use JoinMarket
JoinMarket is a decentralized Coinjoin protocol that brings together peers to mix funds together, gaining strong privacy without relying on a central coordinator, without giving fees to a central entity, etc.
The best way to get started today is using the new UI built around JoinMarket, @jamapporg:
jamapp.org
