MPC

Every crypto wallet is controlled by a private key, or a secret number that authorizes transactions. Whoever holds the key controls the assets. 

Multi-party computation, or MPC, is an upgrade to how crypto wallets handle security, distributing key control instead of concentrating it in one place.

How MPC works

Instead of a single key sitting on one device, MPC splits the key into separate pieces and distributes them across multiple parties or devices. No single piece is enough to move funds on its own. When a transaction needs to be approved, each party contributes their piece to a shared computation. The result is a valid signature, but the full key is never assembled anywhere in that process.
