Zenrock

Zenrock is a permissionless MPC (Multi-Party Computation) infrastructure that enables decentralized key management for cross-chain protocols and wallet builders, eliminating single points of failure through distributed private keys. Through its zrSign technology, it provides developers with tools to build secure omnichain applications that can control assets across any blockchain while maintaining institutional-grade security with hot wallet convenience
