Sparrow Mixing Features and Privacy Concerns

This tutorial is outdated. Mixing feature in Sparrow got dropped after version 1.9.0.

Solid tutorial overall. Just a thought: why not set up Sparrow as a daemon with systemd so it starts up automatically?

Mixing without Tor is pointless. The whirlpool coordinator can trace your mixes through your IP. No privacy there.

Thanks for sharing that! But it doesn't really change the tutorial's core info. If you have more details, I’m open to adding them.

To get started, just run a Tor daemon on your Raspberry Pi. Then in Sparrow, go to Preferences and set the proxy to use Tor. Route all your traffic through it. Amazing setup for smooth coinjoins!

Thanks for the tips! But who says I’m not running my own mempool? I actually have a couple of nodes. 1. Umbrel on RPi with core, electrs, dojo, and more. 2. Raspbian Lite, clean setup with core, electrs, Sparrow.

Been there with Sparrow wallet. Connecting was tricky for me too. No firewall, yet it just wouldn’t connect. Public Electrum servers failed too.

You gotta think about endless free coinjoins... Sybil attackers thrive on it. They mix freely, while genuine users get hurt.

That's a nice setup! Do you use Samourai along with your Dojo? And have you checked your logs yet? My experience has been way better; Sparrow connected to my node like a breeze.

Right now, I use Sentinel for a few addresses and Zeus for my LND node. Love Zeus for forcing a connection to my node. Also, dev is super chill. We chatted once!

I’ve gone further too. Added my cold wallet’s pub key in Sparrow, set postmix UTXOs to auto send there after mixing. Super easy to set it and forget it.

Quick question: can you bring a cold storage wallet online and continue remixing? Like if I mix my outputs to a cold wallet, could I later import that wallet into Sparrow to remix again?

Nah, you probably can’t do that. When adding the seed, four accounts are created. Maybe it won’t even need to send coins around.

Shouldn't it generate keys via the seed? Did you try importing individual private keys instead?

Only tried the seed phrase so far. I could kick off a new hot wallet with it. Hopefully the UTXOs land in the right spot.

So if I make a cold Sparrow wallet, set it to coinjoin, then mix coins to the xpub of that cold wallet, can I later use it online and continue mixing? Yeah, you can add those accounts manually too.

I'll test it out and update when I have results.

Tried it! No luck. Couldn't create whirlpool accounts for airgapped wallets. I could only add simple accounts. Had to make a hot wallet in Samourai instead.

C'mon, that's just FUD. Those issues aren’t unique to Whirlpool CoinJoins. Same goes for Wasabi without good coin control.

You’re spreading FUD here! Whirlpool does show common ownership, and peeling chains are real. Wasabi's mixes don’t reveal that.
