## MPC Wallet Architecture

MPC Wallet Architecture refers to the technical design of cryptocurrency wallets that utilize secure multi-party computation to manage private keys. Unlike traditional wallets that store a single private key in one location, MPC wallets generate and store fragmented key shares across distributed infrastructure.

When a user initiates a transaction, the wallet orchestrates a computation across these distributed shares to produce a valid signature. This architecture eliminates the single point of failure inherent in mnemonic phrases or single-device storage.

It allows for flexible policy enforcement, such as requiring multiple approvals for large trades or integrating with existing corporate governance workflows. This design is increasingly favored by exchanges and institutional custodians for its balance of security and operational efficiency.
