# Protocol Admin Control

MSafe Wallet can be used to enable protocol administrative control functions, such as:

* Protocol key parameter change
* Emergency stop
* Community reward change.

By using a multi-sig wallet like MSafe, admin control functions can be safely executed, avoiding single points of failures or fraudulent activities by a single bad actor.
