CoinJoin protocol requires multiple parties to jointly sign a digital smart contract to mix their coins in a new Bitcoin transaction, where the output of the transaction leaves the participants with the same number of coins, but the addresses have been mixed to make external tracking difficult. By mixing multiple transactions, users can effectively “break the chain” of traceability, making it difficult for third parties to determine the sender and recipient of a particular transaction.

We don't use an existing CoinJoin protocol, it's built by our own strategies. Our Improved verison ensures user privacy by simultaneously mixing transactions from multiple users. It employs distinct wallet gateways that are ne-ver reused, preventing fund traceability. While users might think they can trace transactions, the source of obtained funds remains concealed. This guarantees the confidentiality of blockchain exchanges, eliminating concerns about mixing old and new transactions.

All our users are protected against accidental errors or deliberate actions by means of the guaranteed letters. For each mixing request, we issue a digitally signed letter of guarantee, which confirms our obligations to the client.

You can download your Letter of Guarantee on the transaction page. It's your unique transaction proof, it's your signed transaction. By providing you with a Bitcoin address to send your coins, we also provide you with a digitally signed confirmation. This letter must be sent to our support email in order to route the transaction in case of unexpected problems.

Tengri ensures the confidentiality of your transactions, so it is our duty not to keep a record of your requests within our service.

Choosing higher fees allows your transaction to have a higher priority level. Each fee value uses a different protocol allowing for faster transactions. This is an average delay of about one hour with high fees and about 3 hours with lower fees. The exact delay cannot be predicted due to variations in the blockchain.

A higher service fee increases the speed and also makes your transaction more anonymous. The customer can decide for himself if he decides to give a higher percentage to our service. Indeed, if a customer chooses a delay, the service fee no longer depends on the speed of the transaction but is only an indication of confidentiality.

Why would using a high service fee increase confidentiality? Because the difference between the incoming amount and the outgoing amount will be greater, which will reduce any possible link between the two amounts.
