Kayra is a decentralized dark pool exchange based on orderbook MPC. No MEV, no front-running, minimal market impact. Pre-trade and trade execution privacy from everyone on public blockchains. Post-trade privacy on Aleo.
No party can see your orders until they are executed. Build on Aleo and Nillion MPC compute cluster.
Your on-chain activity cannot be linked to trading before the trade is executed.
We never take custody of your funds. Withdraw unilaterly any time.
Our Orderbook Darkpools are powered by Aleo and Nillion MPC
To start trading, tokens are sent to a never-seen-before address. External observers, including Kayra operators, have no way to determine that this transfer is a deposit to Kayra.
Kayra nodes receive a zero-knowledge storage proof of the deposit. This proof guarantees that you have enough funds to submit an order, but does not reveal your address or the exact amount.
The order submitted to the Nillion MPC cluster contains encrypted information required to match the order and settle it. Original order is reconstructed and revealed only when it is successfully executed.
Kayra is deployed on Aleo Testnet, Ethereum Sepolia and Nillion testnets
Connect Metamask to Ethereum Sepolia Testnet Keplr to Nillion testnet. Leo Wallet to Aleo Testnet
Open our faucet and mint some test wETH and USDC to trade
Deposit wETH or USDC to Kayra
Use Keplr to pay for storing and executing an encrypted order
Kayra is in active development and our whitepaper will be soon released. Meanwhile, if you have any questions or just want to chat, we’d love to hear from you!
Our aim is to achieve CEX-like performance and full price discovery via stealth order books.
No, Kayra is designed to be fully compliant and guarantees pre-trade and trade privacy. That said, our DEX can be run on top of the privacy preserving blockchains and protocols to additionally offer post-trade privacy.
Our priority are Aleo, EVM-compatible chains/L2s and Solana. Currently, Kayra is only deployed on Aleo and Ethereum Sepolia Testnets.
