Crypto Tumbler
Anonymous mixing for BTC, ETH, SOL · fee you set
Northmix is a crypto tumbler that works across Bitcoin, Ethereum, Solana and stablecoins. The same deposit-and-payout model that powers the Bitcoin mixer is available for every supported asset. You deposit coins from any wallet, the service pays you out from a separate output pool, and the on-chain link between your input and your output is broken. No account, no email, no KYC. The full workflow is on the how it works page.
What is a crypto tumbler?
A crypto tumbler is a privacy service that accepts cryptocurrency from one address and pays out the same cryptocurrency to a different address from a pooled output. Because the output coins did not come from your deposit address, a third party watching the ledger cannot draw a direct line from your input to your output. The term "tumbler" and "mixer" are used interchangeably; both describe a crypto mixing service that breaks on-chain links.
Northmix is a privacy mixer rather than a CoinJoin coordinator. The deposit and the payout happen at different times, from different addresses, with optional rounds and delay that further weaken timing-based correlation. The result is a stronger break of the on-chain link than a single CoinJoin round, with a simpler user experience: you do not need to coordinate with other users or wait for a round to fill.
Supported cryptocurrencies
Northmix supports eight assets across twelve networks. Each asset is bound to one or more supported networks, and tokens that share a ticker on different networks are treated as separate configurations. The full catalog with decimals and supported networks is on the supported assets page.
| Asset | Ticker | Type | Networks |
|---|---|---|---|
| Bitcoin | BTC | Native | Bitcoin |
| Ethereum | ETH | Native | Ethereum, BNB Smart Chain |
| Tether | USDT | Token | Ethereum, BNB Smart Chain |
| USD Coin | USDC | Token | Ethereum, BNB Smart Chain |
| Litecoin | LTC | Native | Litecoin |
| Solana | SOL | Native | Solana |
| BNB | BNB | Native | BNB Smart Chain, Ethereum |
How crypto tumbling works
Tumbling on Northmix follows the same three-step flow regardless of asset. The app guides you through each step, and the fee is shown on its own line before you confirm anything.
- Enter a payout address. Provide a fresh destination address in the asset you are mixing. The address should have no on-chain history tied to your deposit wallet.
- Send coins to the deposit address. Northmix generates a one-time deposit address for the asset and network you selected. Send your coins there from any wallet, then submit the public transaction hash so the service can verify the deposit.
- Receive clean coins. Once verification completes, the service pays out to your payout address from its output pool. The coins you receive are unlinkable to your deposit.
You can choose between one and five rounds and a delay of 0 to 72 hours. More rounds push the output further from the input through additional pool hops; a longer delay makes time-based correlation harder. The fee you set is applied regardless of the rounds and delay you select, as documented on the fees page.
CoinJoin alternative
CoinJoin is a coordination protocol that merges multiple users' transactions into a single batch transaction. It is a public, multi-party construction: every participant's input and output appear in the same transaction, and the privacy gain depends on how many other participants are in the same round. CoinJoin is Bitcoin-only and requires coordination with other users at a specific time.
Northmix is a CoinJoin alternative that does not coordinate multi-party batches. The deposit and the payout are independent transactions at different times and from different addresses. This has two practical effects. First, the user experience is simpler: you do not wait for a round to fill or coordinate with other users. Second, the separation between input and output is stronger than a single CoinJoin round, because the two never appear in the same transaction. The trade-off is that you trust the service to handle the output pool honestly, which is why Northmix is transparent about its fee model and its no-KYC and no-logs posture.
Privacy and security
Northmix is a no KYC mixer. 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 transaction hash, the public transaction reference, and the public payout address. Northmix does not write wallet data to browser storage, sessionStorage or cookies. Outbound explorer links open with rel="noopener noreferrer nofollow" and the referrer is suppressed.
Northmix security model is documented on the security page, including the strict Content Security Policy, the safe DOM rendering rules and the input validation logic. The data handling policy is on the privacy page. For common questions about legality, payout times and minimum amounts, see the FAQ.
