Multi-Chain MPC

Definition

Multi-Chain MPC is a key concept in institutional digital asset infrastructure. BIP-44 HD derivation from a single master key generates chain-specific keys for 13 blockchains via MPC cosigner.

Why It Matters

Digital asset security is the foundation of institutional trust. A single security breach can result in hundreds of millions in losses and permanent reputational damage. Multi-Chain MPC represents a critical component of the multi-layered security approach required for institutional-grade custody.

How JIL Sovereign Addresses This

JIL implements multi-chain mpc as part of its defense-in-depth security architecture. BIP-44 HD derivation from a single master key generates chain-specific keys for 13 blockchains via MPC cosigner. The platform combines MPC 2-of-3 threshold signing, post-quantum cryptography (Dilithium/Kyber), AES-256-GCM encryption at rest, and hardware security module integration across all 10 mainnet Sovereign Compliance Network (SCN) validators.
