zkLink is a unified, multi-chain trading infrastructure secured with ZK-proofs, aiming to solve liquidity fragmentation across different blockchain ecosystems. Its mission is to create a seamless and secure trading experience by aggregating liquidity from various Layer 1s and Layer 2s into a single, interoperable Layer 3 network. This allows developers to build decentralized applications (dApps) like order book DEXs, AMMs, and NFT marketplaces with access to deep, unified liquidity. The project was founded to simplify the multi-chain crypto landscape for both developers and end-users.
