Bitcoin Privacy: Coinjoin Best Practices for Hardware Wallet Users
1253 sats \ 6 comments \ @PictureRoom 10h bitcoin_beginners
I'm working to improve my coin control and privacy practices. My bitcoins currently sit on a Blockstream Jade and come from various traceable sources (exchanges, P2P, Alby, etc.).
I want to obfuscate these transaction histories.
My understanding so far:
Need to transfer from Jade to a hot wallet for coinjoining Sparrow offers "fake coinjoins" (Stonewall transactions) that work solo Real coinjoins require coordination but offer stronger privacy
Specific questions:
Workflow confirmation: Is Jade → hot wallet → coinjoin → new cold storage the right approach? Tool choice: Sparrow vs Wasabi for someone prioritizing hardware wallet integration? Stonewall vs collaborative coinjoins: When is fake coinjoin sufficient vs needing the real thing? Common mistakes: What privacy-killing errors should I avoid? UTXO management: Best practices for managing mixed vs unmixed coins?
I've read Sparrow's docs on private spending but would love real-world insights from those who've implemented robust privacy practices.
What's worked best for your setup?
Goal: Effective privacy without overcomplicating my security model.

You can use the only HWW with native coinjoin: https://wasabi.kravens.nl/#trezor

You should do several rounds of coinjoining, ideally some as taker and some as maker. You can use JoinMarket for that.
An alternative is to swap in and out of Lightning Network. For less than 5M sats this is probably cheaper than the coinjoins. Tool: SwapMarket
It's important to understand your threat model and the sources.

For the receiver privacy in LN you can use something like https://lnproxy.org/ that's not custodial.
Another option that would be the cheapest is to use a custodial service like coinos to do the LN swapping. But I wouldn't do it for significant amounts tbh.

There aren't a lot of privacy options these days... for obfuscating on-chain. In the future a 'blend' of privacy and transparency will be most realistic as perfect privacy is really difficult.
Imo probably the most 'decentralized' survivable coinjoin available is joinmarket. Read about it here: #521035 https://github.com/joinmarket-webui/jam
Best of Luck

the coinjoin wallet will take one seed and give you 4 address collections:
deposit_utxo mixing_utxo coinjoined_utxo busted_transactions
you send from jade->deposit
use the coinjoin tool to spend from deposit->mixing
Consolidate out of mixing->coinjoind
if anything goes awry, the utxo ends at busted
you might be able to restore the coinjoined_utxo address collection to your new hardware wallet, if you get your derivation path setup correctly. this would be helpful because you decrease anonymity if you spend more than one joined utxo at a time
somebody correct me if I'm wrong, plz

Wait - doesn't Jade support HWI? Because at least Wasabi supports HWI.
