On this page, select Edit next to Entity Policy to set approval requirements needed to successfully process entity-level activities.

The existing consensus requirements must be met to process updates to the consensus security settings.
The ability to use a role on behalf of a portfolio or the entire entity depends on the Access Level the Team Member is assigned.
Entity-level users can use their permissions across every portfolio (current and future) in the entity and for activities that affect the entity itself.
Portfolio-level users can only use their permissions to action per each portfolio they have access to.
For more information regarding Access Levels, please visit this Help Center article: Access Levels on Coinbase Prime
