Coinomize
Yes. Like every pooled Bitcoin mixer, Coinomize holds funds briefly between deposit and withdrawal — that's the whole mechanism. The PGP-signed letter of guarantee is the cryptographic commitment that protects users during that window. If anything ever went wrong, the letter is the document you'd take to a public dispute.
Bitcoin privacy mixer
Restore privacy to your Bitcoin transactions with Coinomize.
Bitcoin is a public ledger. Every transfer leaves a trail that chain-analytics firms read like a phone book. Coinomize is a pooled BTC mixer that breaks that trail — your deposit and your withdrawal stop being the same coins on the blockchain.

What it is
A Bitcoin mixer focused on one job — done well.
Coinomize is a BTC mixer (sometimes called a tumbler) that takes incoming BTC, pools it with deposits from other users, and sends fresh, unconnected coins from its own reserve to the destination addresses you specify. The transaction history that leads back to your old wallet stops at the pool. From there, on-chain analysis hits a dead end.
The service has been operating under the same brand since 2019. It handles Bitcoin only — no Ethereum, no stablecoins, no chain-hopping. Single-asset focus keeps the codebase narrow, the reserve deep, and the attack surface small. Those three things are what actually matter in a mixer, regardless of what the marketing pages of competitors say.
Why people choose it
Here are a few factors why Coinomize is the best mixer.
PGP letter of guarantee
Issued before you send anything. A cryptographically signed document tied to the mixer's published key — your proof of what was promised.
Customisable delay
Pick anywhere from instant to 96 hours between deposit and withdrawal. The delay window breaks temporal correlation between transactions.
User-set fee, randomised amount
You pick the fee inside a range. The mixer randomises the final value so what comes out never exactly equals what went in. Amount-based correlation fails.
No-logs policy with TTL
Set the log retention to as little as 1 hour, up to 7 days. After that window, the link between deposit and withdrawal is gone from the server.
Up to 10 output addresses
Split your withdrawal across multiple wallets in a single mixing session. Each address gets a different delay and amount.
Onion mirror available
Tor v3 onion address published and signed alongside the clearnet domain. Use whichever fits your threat model.
Six steps from deposit to clean coins
How Coinomize works?
The interface stays short on purpose. The interesting work happens server-side — pool selection, fee randomisation, time-locked release — but the user surface is six fields and one confirmation.
- Enter your destination addresses One to ten Bitcoin addresses where the clean coins should arrive. Each one can have its own share of the deposit.
- Pick a delay for each output Anywhere from instant to 96 hours. Different delays for different addresses make timing analysis harder.
- Choose the service fee Set a value inside the allowed range. The final amount is randomised so it doesn't exactly match the deposit.
- Download the letter of guarantee A PGP-signed document listing your deposit address, output addresses, fee, and delay. Save it before you send anything.
- Send BTC to the deposit address Send from any wallet you control. The mixer waits for one confirmation before queuing the withdrawal.
- Receive coins from the reserve Once the delay elapses, Coinomize releases fresh BTC from its pre-existing pool. These coins have no on-chain link to your deposit.

Quick answers
Three questions worth answering up front.
Deposits start from 0.005 BTC. The upper limit per transaction depends on the current reserve and is shown before you confirm parameters. For larger sums it's common practice to split into separate mixing sessions on different days.
Operational logs are kept only for the retention period you choose at the start of the mix — minimum 1 hour, maximum 7 days. After that window the link between deposit and withdrawal is removed from the servers. The full FAQ covers what's logged in detail.
