Summary

Chain signatures is an MPC service that facilitates the ability to sign arbitrary payloads by calling into a smart contract and eventually getting back a signature. This signature can be used for various purposes such as deriving new public keys associated to foreign chains (Ethereum, Bitcoin, etc.).
