I vividly remember the case of Harvest Finance ($FARM) where there was an exploit in the systems, using flash loans, and users collectively lost $25M. I was in another group where they were discussing if cover through Nexus Mutual purchased by the protocol, from treasury, would have covered every user who lost money.
Is that something that NexusMutual can do? If not, perhaps in the future. Seems like there is a solid business case for the protocol itself to get insured.
