Union is a leading zero-knowledge (ZK) interoperability Layer 1 blockchain that serves as the settlement and liquidity layer for protocols and asset issuers. Unlike other interoperability protocols, Union does not rely on trusted third parties, oracles, multisignatures, or multi-party computation (MPC).Its high-performance ZK interoperability layer enables seamless asset issuance and scaling across thousands of blockchains, while maintaining security, efficiency, decentralization, and speed. This makes Union the first-of-its-kind solution in the space, committed to achieving sub-second cross-chain settlement — shaping the ultimate vision of a truly interconnected, cross-chain future.
