How to use Coinomize mixer — a working guide.

Reading this once is enough to walk through your first Coinomize mix without surprises. The interface is short on purpose, but several of the fields have non-obvious effects on the privacy of the result. Take the five minutes — it's worth it.

Before you open the mixer

Two things to have ready: a source wallet that holds the BTC you want to mix, and a destination wallet that has never received any of those coins. Ideally the destination is a fresh wallet, not a new address inside the same wallet as the source — the privacy mix only protects the on-chain link, not any record kept by the wallet software itself.

If the destination wallet is a hardware device, generate the addresses there in advance and copy them out as text. If it's a custodial exchange wallet, reconsider — withdrawing to an exchange that performs chain-analysis on incoming deposits can re-link the funds to your verified identity in seconds, undoing the work the mixer just did.

The 8 steps in order

1. Prepare a fresh destination wallet Generate one or more new BTC addresses in a wallet that has never received your old coins. Native SegWit (bc1q) or Taproot (bc1p) is fine.
2. Open Coinomize and verify the URL Check the TLS certificate or, if you're on Tor, the v3 onion address character-for-character. Mixer phishing is real.
3. Enter your output addresses Up to 10. Set the percentage split between them. Uneven splits look less obviously generated than 50/50 or 33/33/33.
4. Pick a delay for each output Vary the delays — 4h, 22h, 51h is more useful than three identical 24h delays. The total window can stretch across days.
5. Choose the service fee inside the range Anywhere from 0.5% upward. The mixer randomises the final value within the band so the output amount never matches the input exactly.
6. Save and verify the letter of guarantee Download the PGP-signed text file. Run gpg --verify against the public Coinomize key. If it doesn't check out, stop.
7. Send BTC to the deposit address Send the exact amount shown. One on-chain confirmation queues the withdrawal. Don't reuse the deposit address — it's single-use.
8. Wait, then verify arrival Withdrawals begin after the configured delay. Watch your destination wallet. If anything misfires, the letter is your proof.

The main mistakes of newbies using Coinomize mixer

Sending from a KYC exchange directly into a mixer. The exchange already knows the source amount, the timestamp, and your identity. Move the funds to a self-custody wallet first, wait a day or two, then mix from there.

Using identical delays and amounts for every output. Variation is the point. If all three outputs land on the same block with rounded amounts, you have given the analyst a clean correlation pattern. Mix it up.

Skipping the PGP verification. The letter of guarantee is useless if its signature is not actually from the Coinomize key. A clone site can sign a fake letter with its own key and you'll never know unless you check.

After the mix

The wallet you withdrew into is now "clean" relative to the wallet you started with — there is no on-chain link between the two. To keep it that way, treat it as a separate financial identity. Don't consolidate it back with the source wallet. Don't send it straight to an exchange that performed KYC on the original funds. Re-mixing later, if your circumstances change, is faster than recovering privacy that's been broken downstream.
