TLDR: Aztec <> Superchain Bridge
Kage Kurō is a privacy-focused cross-chain bridge that facilitates confidential asset transfers between Aztec and Optimism (Superchain ecosystem). It utilizes Merkle proofs to securely aggregate and verify transaction intents, ensuring trust-minimized interoperability. Integration with EigenDA enhances scalability and data availability, maintaining privacy and efficiency in cross-chain operations.
Summary:
We propose Kage Kurō, a privacy-first cross-chain bridge that connects Aztec with Optimism in the superchain ecosystem. Our system enables confidential asset transfers by creating “intents” on the source chain, which are hashed and recorded in a Merkle tree. Off-chain relayers aggregate these intents and transmit the aggregated Merkle roots (secured via threshold signatures) to the target chain using protocols like LayerZero, with EigenDA ensuring decentralized data availability. On Optimism, solvers verify individual intents using Merkle proofs before executing asset transfers and claiming reimbursements. This approach ensures trust-minimized, efficient, and private cross-chain interoperability, reducing gas costs and enabling selective disclosure for regulatory compliance.
About Us (Kage Protocol):
Kage Protocol is a portal to private DeFi comprising of a suite of products that enable users to interact with decentralized finance while preserving confidentiality at every layer. Our team comprises blockchain engineers and cryptographers with relevant experiences in:
Zero-knowledge proofs (ZKPs) and privacy-preserving computations.
- Cross-chain interoperability and bridging protocols.
- EVM-compatible smart contract development and emerging ERC standards (e.g., ERC-4337).
Kage Protocol was built to redefine the DeFi landscape by ensuring that every transaction from payments to lending and staking is executed with uncompromised privacy.
