Micta

Micta is a Privacy-Enhanced Orderbook Bridge that empowers users with secure and anonymous cross-chain transfers and order placement. When users log in to the dApp, they provide an address to receive the requested funds and gas. Micta facilitates asset transfers (ETH, USDC, USDT) from Oasis Sapphire to Ethereum Mainnet or Arbitrum Mainnet via its main contract.

Using Hyperlane, Micta transmits liquidity and interacts with an order bridge contract, triggering Venn contract verification to validate the transaction. Once validated, the order is listed anonymously on the Cowswap orderbook, preserving user privacy. Upon execution, the provided wallet receives the funds and gas directly, completing the trace-free transaction.

Micta leverages several cutting-edge technologies:

Hyperlane: Enables seamless cross-chain messaging for asset transfers and order routing. Cowswap: Serves as the orderbook for anonymous order execution. Venn Contracts: Ensure robust validation and compliance for transaction requests. Oasis Sapphire: Provides privacy-enhanced transaction execution as the liquidity source. Smart Contracts: Solidity-based main contract handles asset routing, validations, and bridging operations. Frontend: React.js interface with wallet integration for user interaction and transaction initiation. Backend: Node.js services support off-chain computations and facilitate the interaction between contracts and the Hyperlane API. Hacky or notable implementations include using advanced privacy-preserving mechanisms and leveraging off-chain components for validation without exposing user data on-chain.
