Arch Insurance International has authorized cryptocurrency insurer Evertas to offer the highest coverage limit in the industry, setting it to $420m for security policies in the event of theft of private crypto keys held by a custodian. It follows losses of $3.7bn in 2022 and $400m in Q1 2021. Lloyd's of London coverholder Evertas is only contracted to provide insurance for custodians and has also been approved to provide policies for physical cryptocurrency mining equipment of up to $200m. Currently only 2-3% of global cryptoassets are insured.
