Frequently Asked Questions
Bitcoin mixer & crypto tumbler — frequently asked questions
This page answers the most common questions about Northmix, a no KYC Bitcoin mixer and crypto tumbler. The full mixing flow is on the how it works page, and the technical reference is on the documentation page.
What is a Bitcoin mixer?
A Bitcoin mixer (also called a BTC mixer or Bitcoin tumbler) is a privacy service that accepts BTC from one address and pays out BTC to a different address from a pooled output. Because the output coins did not come from your deposit address, a third party watching the blockchain cannot draw a direct line from your input to your output. Northmix extends the same model to ETH, USDT, USDC, LTC, SOL and BNB. See the Bitcoin mixer and crypto tumbler pages for the full explanation.
Is mixing legal?
Mixing cryptocurrency is legal in most jurisdictions. It is a privacy tool used by people who do not want their full wallet balance, salary or savings publicly traceable on a public ledger. The legal status of mixing services varies by country and changes over time, so you are responsible for understanding the rules that apply to you, including any tax reporting obligations on the coins you receive. Northmix does not provide legal advice and does not make any claim about absolute anonymity. The service is not designed to help anyone hide proceeds of crime.
Do you require KYC?
No. Northmix is a no KYC mixer. There is no sign-up, no email, no identity check. Northmix never asks for a seed phrase or a private key and rejects input that looks like one. The only data handled in memory is the selected asset and network, the amount, the public payout address, the public transaction hash, and the public transaction reference. See the privacy page for the full data handling policy.
How long does a payout take?
A payout is broadcast after the deposit confirms on-chain and the optional delay you selected has elapsed. The delay can be anywhere from 0 to 72 hours. Once the payout is broadcast, the time to reach your wallet depends on the network: Bitcoin blocks are roughly ten minutes apart, Ethereum and BNB Smart Chain are seconds apart, Solana is sub-second. Each network requires a different number of confirmations before the transaction is considered settled, as listed on the supported networks page.
What is the minimum amount?
The minimum amount is set per asset and per network so that the fee you set and the network fee do not eat the entire payout. Northmix rejects amounts below the minimum at validation time, before a deposit address is shown. Always check the fee summary on the configuration screen before sending a deposit, because the estimated network fee is shown separately from the service fee, as documented on the fees page.
Which networks are supported?
Northmix supports five networks: Bitcoin, Ethereum, BNB Smart Chain, Litecoin and Solana. Seven assets are mapped onto these networks: BTC, ETH, USDT, USDC, LTC, SOL and BNB. Each (asset, network) pair is a distinct configuration, so USDT on Ethereum and USDT on BNB Smart Chain are not interchangeable. The full catalog is on the supported assets page.
Do you keep logs?
Northmix does not write wallet addresses, transaction hashes, payout addresses or user input to browser storage, sessionStorage or cookies. All session state lives only in JavaScript memory and is cleared when the page is unloaded or when the user disconnects a wallet. No third-party analytics, advertising or telemetry destinations are contacted. Outbound explorer links open with rel="noopener noreferrer nofollow" and the referrer is suppressed. This is the no-logs posture at Northmix layer; privacy obligations are defined separately by the service team. See the security page for the full application security model.
How do rounds and delay work?
Rounds and delay are the two parameters that control how strongly your output is separated from your input. A round is one full mix cycle. You can pick between one and five rounds. One round breaks the direct link between deposit and payout; more rounds push the output further from the input through additional pool hops. Delay is the time between the deposit confirming and the payout being broadcast, in the range 0 to 72 hours. A non-zero delay makes time-based correlation harder. Rounds and delay are independent, and the fee you set is the same regardless of the combination you pick. See the how it works page for the full explanation.
