How MPC Solves the Single-Key Compromise Problem

Traditional private key management relies on a single 256-bit ECDSA secret string. If that single secret is extracted from memory or physically stolen, all deposited vault capital is immediately lost. Multi-Party Computation (MPC) splits the mathematical private key into encrypted key shards (partial signatures). The key itself NEVER exists in complete form at any single location, memory address, or node. Key Advantages of MPC over Traditional Multisig: - Gas-Efficient: Computed signatures render as standard single-key transactions on-chain. - Dynamic Key Refresh: Key shards can be rotated periodically without altering the public wallet address. - Hardware Isolation: Key shares execute inside Intel SGX secure enclaves.
