File a claim

A claim is filed against cover you hold, in the Nexus Mutual app. The Claims Committee assesses it against the cover wording and votes on the outcome.

Before you start​

You must hold the cover and be a member. If you bought cover without joining, you need to join before you can claim.

Check two things first:

  • the grace period has not passed. You can claim after cover expires, but only within the grace period set by the product. It varies, from a couple of weeks to several months.
  • the loss meets the cover wording. The wording defines what counts as a loss and what is excluded. If there is a deductible, losses below it are not claimable.

The Claims Committee can help you check both, and calculate the loss, before you file. Reach them through the in-app chat or the contact form. Doing this first is worth it.

The deposit​

Filing requires a deposit of 0.05 ETH, submitted with the claim.

  • Claim accepted — the deposit is returned along with the payout.
  • Claim assessed as a draw — the deposit can be retrieved.
  • Claim denied — the deposit is not returned.

It exists to make frivolous claims cost something. It is not a fee on genuine claims.

What you submit​

Incident details. What happened, when, and where. Links to the transactions, a post-mortem, or anything else that establishes the event.

Proof of loss. For most cover this was recorded when you bought it — the addresses or positions the cover applies to. Where it was not, you provide it now.

The amount. What you are claiming, after any deductible. It cannot exceed the cover amount.

You review everything before it goes onchain.

What happens next​

The Claims Committee reviews the claim and votes. Voting stays open for at least 72 hours, and assessors record the reasoning behind their vote, which you can read once voting closes.

A 24-hour cooldown follows, during which the Advisory Board can act if a vote was fraudulent.

If the claim is accepted you have 30 days to redeem the payout. It is paid in the cover asset, from the capital pool, and the stake backing that cover is burned.

If your claim is denied​

You can file again. A denied claim is usually a claim the evidence did not establish, so another submission is worth making only with something the first one lacked — a clearer link between the loss and the covered position, or evidence of the amount.

The reasoning recorded by the assessors tells you what was missing.
