## MPC Signing Protocols

MPC signing protocols are specific implementations of multi-party computation tailored for the creation of digital signatures. They enable a group to sign a message such that the signature is indistinguishable from one produced by a single private key.

This is achieved by distributing the signing algorithm across multiple devices, where each device computes a part of the signature based on its secret share. These protocols are highly secure because they eliminate the need to combine shares in a central location.

MPC signing is widely used in modern crypto-custody solutions to provide high-performance, secure transaction signing. It allows for the integration of complex business logic, such as approval workflows, directly into the signing process.

The protocols must be carefully designed to prevent side-channel attacks and ensure that the signature process is atomic. MPC signing is a foundational technology for institutional DeFi adoption.

It provides the necessary security for managing large volumes of assets in a decentralized manner.
