Access Control

With the exception of the allow list, all functionalities in Sablier can only be triggered by the users. Sablier admin has no control over any stream or any part of the protocol.

This article will provide a comprehensive overview of the actions that can be performed on streams once they are created, as well as the corresponding user permissions for each action.

note

Every stream has a sender and a recipient. Recipients can approve third parties to take actions on their behalf. An unknown caller is any address outside of sender and recipient.
