Through Ledger Vault, Nexo offers insurance of up to $150 million for its customers' crypto holdings through a specially tailored insurance program provided by Arch and Marsh. Additionally, Nexo has partnered with Bakkt as its wallet custodian, with the company's storage facility being insured for a further $125 million. It's essential to understand while Nexo is insured against a hack, theft, or loss of private keys, its policies do not protect against bankruptcy. Therefore, worth utilizing a safe hardware wallet to ensure the safety of long-term investments.
