Private Send is a method of sending funds that protects user privacy. Through this feature, you can complete transfers between a sending wallet and a receiving wallet without establishing a direct on-chain link, providing enhanced privacy protection for daily transactions.
After using Private Send, the original wallet and the destination wallet will not form a direct transaction trail on the public ledger.
How Private Send Works
Private Send is supported by partner service providers. The process is as follows:
You initiate a send as you normally would.
Funds are first sent to the partner provider's receiving address.
The provider routes the transaction, including transfers between multiple centralized exchanges.
This process may incorporate privacy networks, such as Zcash or XMR, to further break the on-chain link.
After passing through multiple routing layers, the funds eventually arrive at your designated receiving address.
Under the hood, these transactions are routed through regulated centralized exchanges and privacy networks (e.g., Zcash, XMR, etc.) to break the on-chain association between the two wallets while adhering to applicable compliance requirements.
Please note that Private Send is not an on-chain mixer; it is a practical privacy protection solution that leverages mature centralized exchange infrastructure and privacy networks.
Features of Private Send
Consistent User Experience: The sending process is essentially the same as a normal transfer, requiring no additional learning curve.
Stronger Privacy Protection: The source wallet and the receiving wallet have no direct transaction trail on the public ledger.
Typically No KYC Required: In normal circumstances, identity verification is not required; however, based on the source of funds, risk identification results, or jurisdictional requirements, KYC or other verification processes may be triggered.
How long do transactions take
Since Private Send involves multiple transaction parties and more complex processing, the arrival time is usually longer than standard transfers.
Most transactions are completed within 10–30 minutes. If the BTC network is involved, it usually takes longer.
If you have not received your funds for a long time after submitting a Private Send, it is recommended that you keep the transaction hash and contact the OneKey support team for assistance.
Fees and Slippage Explanation
Private Send involves the following costs:
Service Fee: OneKey charges a 0.85% service fee.
Routing Slippage: Because the transaction requires multiple routings and multi-party processing, the actual amount received will usually be slightly lower than the sent amount.
Transparent Quotation: The service fee, estimated slippage, and final amount received are clearly displayed in the quote, which you can confirm before initiating the transaction.
Common Questions
What is the difference between Private Send and a mixer
These are not the same mechanism.
Private Send does not use an on-chain mixer; instead, it is completed through centralized transaction routing provided by partner providers. The participating exchanges are regulated and screen the source of on-chain funds, so it will not bring additional compliance risks to your wallet.
Does Private Send require KYC
Normally, it does not. However, if the source of funds or the wallet address is flagged by compliance agencies, KYC verification may be triggered.
If you encounter such a situation, please contact the OneKey support team promptly.
Why are there minimum or maximum amount limits
Minimum limit: When the amount is too low, the proportion of routing and network costs is higher, leading to a larger actual wear ratio.
Maximum limit: When the amount is too high, liquidity constraints for the corresponding currency on centralized exchanges may lead to increased slippage.
Therefore, the system sets reasonable minimum and maximum values. For larger amounts, it is recommended to send them in multiple transactions.
How long does Private Send take
Most transactions are completed within 10–30 minutes. If the BTC network is involved, it may take longer.
What if the transaction is stuck
If the transaction exceeds the expected time, for example, if it has not arrived after more than 1 hour, please contact the OneKey support team with your transaction hash for assistance.
