Common questions.

A flat 1% service fee plus a fixed 0.0001 BTC network fee paid to Bitcoin miners. Both are deducted from the amount delivered. No surcharges for delays or split outputs. See Fees & Limits for a worked example.

Minimum 0.001 BTC, maximum 1 BTC per transaction. The minimum exists because very small amounts stand out in the anonymity set. The maximum keeps individual transactions in a range where mixing is unambiguously legal in most jurisdictions where it is legal at all.

Not in a single transaction. Larger amounts should be split into several mixes, ideally spread out in time and routed to fresh receiving addresses. The total fee is higher, but resulting privacy is stronger than one large mix.

An instant mix typically completes within 10 to 20 minutes of your deposit. Most of that time is the first Bitcoin confirmation; the CoinJoin construction itself takes seconds. With a delay selected, total time can range from one hour to about 24 hours.

No. There is no KYC, no account, no email address, no phone number. The only required input is a Bitcoin receiving address.

Up to 24 hours after a mix completes, then removed. IP addresses are not logged. No third-party analytics scripts are loaded. See Security & Privacy for the limits of this guarantee.

Yes. A dedicated .onion hidden service is maintained for network-level privacy on top of on-chain mixing. The current Tor address is published on the official site — verify it there rather than from third-party sources.

During the active mixing window, yes. This is a fundamental property of hosted CoinJoin: the coordinator needs the mapping to construct the joint transaction correctly. After completion, the mapping is removed within 24 hours. If this trust model is unacceptable, wallet-based CoinJoin (Wasabi, JoinMarket) doesn't have this exposure.

The mix waits until the first confirmation arrives. If you set a low miner fee or the network is congested, this can take longer. The transaction identifier issued at the start of the mix can be used to check status with support.

Once a deposit is received and confirmed, the CoinJoin construction proceeds. Cancellation isn't practical at that stage. If you change your mind before the deposit confirms, you can usually replace-by-fee or otherwise abandon the deposit transaction in your own wallet.

Yes. Splitting outputs is supported at no additional charge. It also tends to improve privacy — the resulting outputs are less obviously related to the original deposit amount. Split percentages are configured at the start.

No. Mixing breaks the deterministic on-chain link between input and output in a single CoinJoin transaction. It doesn't erase prior history, hide your IP, or undo identification that happens off-chain. Treat mixing as one layer in a thoughtful setup, not a single switch. See Security & Privacy.

The protocol family is the same. Whir is a hosted service where the operator constructs the CoinJoin on your behalf; Wasabi and JoinMarket let you participate in CoinJoin rounds directly from your own software. Hosted is faster and requires no setup; wallet-based is more trust-minimised. See CoinJoin Technology.

It depends entirely on jurisdiction. Mixing is treated as a normal cryptographic privacy tool in some countries and restricted or prohibited in others. Recent enforcement actions (Tornado Cash 2022, Samourai Wallet 2024) changed the legal landscape significantly. Anyone considering a mixer should understand the laws that apply where they live and to the funds in question. This site does not provide legal advice.
