Cons

Fireblocks's custody insurance is not publicly disclosed.

Frequently asked questions
Is Fireblocks safe?+

Fireblocks uses a mpc custody infrastructure model and scores 66/100 in our independent review, including 62/100 on custody security. One institution can move funds, which is a single point of failure. Safety depends on your priorities; see the full score breakdown above.

Is my bitcoin insured at Fireblocks?+

Fireblocks's custody insurance is not publicly disclosed in a form we can verify. Where it exists, custody insurance covers specific named events up to shared limits and does not cover price loss. Confirm coverage in writing before relying on it.

What happens to my bitcoin if Fireblocks fails?+

Because Fireblocks holds custody through a single institution, recovery in a failure would run through that institution's bankruptcy or resolution process and depends on whether assets were segregated and properly titled. This is the concentration risk of single-custodian models.

Does Fireblocks support inheritance?+

Fireblocks does not advertise a dedicated inheritance or beneficiary feature in the data we track. Confirm current options with the provider, since custody inheritance handling changes.
