Private Transactions on Cardano

Cardano Mixer is a fully decentralized protocol that breaks the link between the sender and the receiver of assets on the Cardano Blockchain, enabling private transactions.

The app is under construction. To contact developers, email us:

Initial Stake Pool Offering (ISPO) has begun!

Initial stake pool offering (ISPO) is a novel method to distribute a protocol’s utility tokens to the community using the Cardano blockchain. It ensures a high degree of decentralization of the token ownership and simultaneously supports the project’s development.

Currently, we are distributing a total of 10 000 000 $MIX tokens (10% of the total supply) to delegators of our very own stake pool with the ticker symbol [CMIX]. Our ISPO started on Epoch 319 (early February) and will continue for 20+ epochs. To participate in the token distribution, users delegate their $ADA to our stake pool [CMIX]. The $MIX rewards are calculated for every epoch individually, so users may decide to participate for any number of epochs.

As you probably know, you can delegate your $ADA to a stake pool in your Cardano wallet app (like Daedalus or Yoroi). It is completely safe, as your funds never leave your wallet. Enter CMIX in the pool search textbox inside your wallet app to find our stake pool. To be sure you are delegating to the right pool, check the pool ID.

Rewards Calculator

Participants of the ISPO can track their accumulated rewards using the calculator below. Enter your stake key to see how many $MIX tokens you have secured so far. The information is updated every epoch (5 days).

Distributed in the ISPO:   2 327 644 $MIX    (out of 10 000 000 $MIX).

Each epoch, we distribute between 100 000 and 500 000 tokens depending on the pool saturation. The per-ADA rewards are higher when the saturation is low. 90% of $MIX tokens are distributed proportionally to your delegation. The rest is distributed through a lottery. You can check the lottery details here.

How does Cardano Mixer work?

Deposit

Generate a one-time-key locally on your machine and deposit native Cardano assets into the smart contract.

Wait

Wait at least a few hours before withdrawing to improve your privacy. Wait longer to receive more significant rewards for anonymity mining.

Withdraw

Present a proof of knowledge of a key for one of the deposits to withdraw funds.

How do we achieve privacy?

Possible deposit amounts are fixed with several options available to the users. For example, when sending ADA privately, you can choose between 200, 1000, and 10000 ADA or use several deposits for a custom amount.

When users withdraw funds, they do not submit the keys for the corresponding deposits. Instead, they send zero-knowledge cryptographic proof of knowledge of a key to unlock one of the deposits.

Any deposit made prior to a withdrawal could be the corresponding potential deposit, though some are more likely than others. The wait before withdrawal increases the uncertainty, thus enhancing the privacy of every user.

Our main features

Governance

The protocol is fully decentralized. Any modification can be done through a vote between MIX token holders. The protocol development past the initial release will be funded using the protocol treasury.

Anonymity Mining

Some users may choose to leave their assets inside the protocol for a substantial time. As it improves privacy for everyone, this activity is compensated from the fees collected by the protocol.

Compliance

The sender and the receiver have information about each other. The information is stored locally on users' devices. Neither the relayers nor the developers have this information. If the users want to share information about their transactions, they can.

Relaying

Users, who stake MIX tokens, can run a relaying service for the protocol. A relayer accepts withdrawal requests from other users (for a fee) and submits transactions on their behalf. Thus, one can withdraw into an empty wallet.

Trusted Setup Ceremony

The protocol is initiated through a trusted setup ceremony. We invite everyone interested in the project to participate. More details on that will be available soon.

Anti-Malicious Use Measures

Tools to prevent malicious use without collecting any data are a part of our design. In particular, with the Cardano ecosystem support, we can efficiently counteract things like crypto ransom attacks.

FAQ

Why should I use a private transaction solution on Cardano?

keyboard_arrow_down

Cardano is a public blockchain. It means that all your transactions are visible and tracked by all kinds of other parties. Such transparency may be undesirable in a situation where your personal information gets linked to your wallet address. It may happen accidentally or, for example, when passing a KYC procedure at a centralized crypto exchange. Cardano Mixer allows you to send a transaction to another user (or to your other wallet) without it being visible on the blockchain.

What are the protocol fees?

keyboard_arrow_down

We expect the total protocol fee (paid by the depositor) to be about 0.2 % of the deposit. This fee will be split between anonymity miners, relayers, and MIX stakers. There is also a Cardano network fee that is expected to be less than 1 ADA regardless of the deposit size (with the current cost parameters). Withdrawing from the protocol is completely free as the transaction is submitted on your behalf by one of the relayers.

How long do I have to wait before withdrawing to get reasonable privacy guarantees?

keyboard_arrow_down

It is possible to withdraw immediately after the deposit has been made. However, it is suggested that you wait for at least a few other deposits into the protocol before withdrawing. The longer you wait, the more uncertainty you create. That is why the protocol pays a part of the collected fees to the anonymity miners.

Does the protocol have minimum or maximum deposit amounts?

keyboard_arrow_down

We will have several preselected deposit amounts in the first version of the protocol. You will be able to choose between 200, 1000, and 10000 ADA deposits at the start. We will add more options, including other native Cardano assets, as the demand rises. If you need to send a custom amount, you could split the sum into several deposits.

Who are the relayers, and how do I become one?

keyboard_arrow_down

Relayers are the critical part of our protocol's decentralized infrastructure. They process withdrawal requests and submit transactions on behalf of the recipients. Thanks to the relayers, it is possible to keep the Cardano network fees low and withdraw into an empty wallet. Relayers collect a part of the fee captured by the protocol. To become a relayer, you need to stake a deposit amount (e.g., 1000 ADA if you want to process 1000 ADA withdrawals) plus a certain amount of MIX tokens and provide relaying service by running our Relayer app.

What is the tokenomics of your protocol token (MIX)?

keyboard_arrow_down

MIX token will have a fixed supply. Most of the tokens will be distributed as rewards to the participants of the trusted setup ceremony, early users, and early supporters of the project. We do not plan a direct public sale. More details can be found in our whitepaper.

Are mixing protocols legal?

keyboard_arrow_down

Different countries have different laws regarding cryptocurrency. Non-custodial mixing protocols are legal in some countries, while others ban mixing large amounts of crypto. We suggest that you find out if mixing protocols are allowed in your country before using our service.

How do I stay compliant?

keyboard_arrow_down

The protocol operates in a completely decentralized manner and is country-agnostic. It does not collect any personal information about the users. However, in some countries, you are required to report all your crypto transactions to tax authorities. The protocol can generate a report of the user's Cardano Mixer transactions (using data from your device).

I want to help the project succeed. What can I do?

keyboard_arrow_down

Right now, you can delegate to our stake pool, follow us on social media platforms, send us your suggestions via direct message or email, and otherwise spread the word. Closer to the release, you could also participate in the Trusted Setup Ceremony (more on that later). We are a small team, so everything counts!
