# Relay Server The Vultisig Relay Server is an infrastructure feature of Vultisig that enables encrypted messaging between user devices over the Internet. The Vultisig Relay Server is nothing more than a messaging service to ensure efficient and smooth messaging between devices that have Vultisig installed. It relays all Keygen and Keysign messages from collaborating user devices completely end-to-end encrypted so that no other party can intercept the information being passed. See the code [here](https://github.com/vultisig/vultisig-relay). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
