After this exploit occurred, claims assessors discussed this loss event in the mutual's Discord server. Because Nexus Mutual is a discretionary mutual, members participate in the Claims Assessment process and review the validity of claims submitted after a loss event occurs.

Claims assessors discussed the event and determined the Perpetual Protocol v1 economic design failure event was covered under section 1.2 of the Protocol Cover wording.

Once the first claim was filed and members were aware of this loss event, the mutual released a statement with information regarding the affected addresses and details about the event, as well as information about the active claims and the Claims Assessment process.
