Decision guide
What matters most before choosing in this category
The right cover depends on which risk you actually need covered, because the exclusions are the product. Two policies with the same headline limit can differ entirely on whether they pay for a custody failure, a governance attack or a depeg. The decisive input is whether the provider has an auditable claims record — paid and denied, with counts and amounts — since that is the only real test of a promise to pay.

Which specific risk are you trying to cover — protocol failure, custody, depeg, or something else?
Can you actually buy this cover as your entity type and in your jurisdiction?
Have you read what the policy excludes, rather than what the headline limit says?

Nexus MutualData checked Sep 2026
The only crypto cover provider with a real, auditable claims record — and it denied 52% of every claim ever…
The only measurable record in the category, and it is published claim-by-claim. Parsing Nexus Mutual's claims page (nexusmutual.io/claims, read again 14 September 2026): 216 claims — 103 APPROVED totalling $18,603,405, and 113 DENIED totalling $5,946,701. That is a 47.7% approval rate by count and 75.8% by value. It is discretionary cover, not insurance, and Nexus says so: 'Cover is discretionary: if you suffer a loss, the Claims Committee assesses your claim against the cover wording.' Note that the widely repeated claim that Nexus members vote on claims is out of date — under V2/V3 a Claims Committee decides, which concentrates the decision that the 52% denial rate turns on.

Methodology
How this category is reviewed
Reviewed on claims actually paid versus denied, what the policy genuinely covers, capital adequacy, and who can buy it. Advertised limits are never scored on their own.

Frequently asked
Questions people ask before choosing defi insurance
Is DeFi cover the same as insurance?
Often not. Some providers here are regulated carriers, some are discretionary mutuals where payout is a member vote, and at least one states plainly that it does not provide insurance coverage for assets. The distinction decides whether you have a contractual claim or a request.
Why does a provider with denied claims rank above one with none?
Because a published record of 96 paid and 113 denied is evidence, and no record at all is not the same as a clean one. Absence of disclosure is scored as risk rather than treated as neutral.
What matters most when picking cover?
Claims actually paid and what is genuinely covered — 60% of the weight between them. Capital backing and whether you can buy it at all follow.
