How Cryptomixer works
Four mechanisms carry almost all the weight in Cryptomixer: the shared reserve, the no-logs design, the time delay, and the letter of guarantee. Read them as a stack — each closes a gap the previous leaves open.
The shared reserve
The heart of Cryptomixer is a reserve: a large stock of coins the service already holds. When you deposit to Cryptomixer, your bitcoin joins that pool, and your payout is drawn from unrelated coins that were never near your wallet. That single swap severs the on-chain link — an analyst following your deposit hits the reserve and loses the thread, because the coins leaving are not the coins that came in.

A reserve alone isn't enough if the operator writes down who sent what to whom. Logs are the weakest point of any mixer: if they exist, they can be leaked, subpoenaed or stolen, and a stored mapping quietly undoes the privacy the reserve provided. Cryptomixer is built so the link between a deposit and a withdrawal is never persisted in the first place — once your mix completes and any support window closes, there is simply nothing on file that reconnects the two ends. Privacy that depends on a promise to delete later is weaker than privacy that never records at all.
Time delay and multiple outputs
Timing and amounts leak more than people expect. A withdrawal that lands seconds after a deposit is easy to pair, and a payout that exactly matches the deposit amount is a giveaway. That's why Cryptomixer lets you set a delay and split the payout across several fresh addresses. The delay lets other deposits flow through the reserve in the meantime, and the split means no single output rebuilds a recognisable total. Together they turn an obvious one-to-one movement into something that blends into ordinary traffic.
The letter of guarantee
Because Cryptomixer holds your coins for the length of the mix, you need proof it committed to the job. That proof is the letter of guarantee: a signed statement issued when you deposit, tying the service's promise to your specific request. If anything goes wrong, the letter is what you present — it is verifiable, it predates the payout, and it doesn't depend on the operator's goodwill after the fact. Keep it until your coins have arrived and settled.
Once these four pieces are in place, the how-to-use page shows how to put Cryptomixer to work, and the security page covers the habits that keep them effective.
