Proposal: Privacy-Preserving Cryptographic Bridge
KRNL Labs is building a trust-minimized, privacy-preserving bridge that enables seamless cross-chain transactions between Aztec and any blockchain levering elliptic curve cryptography (ECDSA, EdDSA, or BLS schemes). This solution leverages KRNL Labs’ established cryptographic bridge and enhances it by integrating aztec.js functionality as an adapter. The modification enables the use of PXE from the node, thereby increasing pre-validation, security, and efficiency.
Immediate Scope
The proposal outlines the development of an MVP that demonstrates secure, confidential cross-chain asset transfers (native and ERC20) between Aztec and selected Ethereum L2s (e.g. Base, Arbitrum, Optimism), with a roadmap for broader interoperability.
