Not
scored

This product is not scored on the Raccoon matrix: it is an audit warranty for audited code only, bought exclusively by a protocol team, not a cover product a retail user can compare against Nexus Mutual's rubric. See the full reasoning on the analysis page. What follows is still real: red flags, open questions and sources.

Red flags Our assessment

01

No complete public product terms: coverage is governed by private, per-engagement agreements. Under the Raccoon methodology this alone triggers an automatic warning.

02

No public information about the capital backing payouts, and Sherlock itself disclaims guaranteed availability of funds: the second automatic warning.

03

The 2023 Euler payout consumed roughly 90% of reserves per press reporting; the current balance of the staking pool is readable live above. The old capital model effectively died with its first big claim.

04

The first two claim instances (Bounty Judge, claims committee) are Sherlock-internal or Sherlock-appointed; independence only begins at UMA, behind a roughly $15k escalation fee.

05

End users are never entitled to anything: payouts go to protocol teams, and Sherlock explicitly warns that users should not assume reimbursement.

06

The auditor insures its own audit: if a covered exploit occurs, Sherlock pays for its own miss. That aligns incentives before launch but creates a conflict of interest in claims assessment.

Open questions Our assessment

Points this analysis could not verify. Anyone buying significant cover should clarify these first.

  • Is the Sherlock V2 staking pool (live above) still the payout basis for Shield, or does Sherlock pay from other, non-public sources?
  • How many Shield engagements are active, and what is the aggregate coverage outstanding?
  • What do the per-engagement terms look like: covered events, exclusions, evidence requirements, deadlines?
  • Has any claim other than Euler ever been paid, and were claims ever denied?
  • Who audits the current Sherlock protocol contracts, and what admin rights and upgrade paths exist?
  • Sherlock’s book was historically also reinsured through dedicated Nexus Mutual product types (Sherlock Excess, Sherlock Quota Share); all 16 protocol-specific listings ever tied to those types currently show zero on-chain capacity (checked 28 Jul 2026). Nexus separately still writes live Sherlock-linked cover today (Bug Bounty Cover, e.g. Usual, $685k), but that product only backs bug-bounty payouts to the covered protocol, not Shield’s own exploit payouts. Does any current capital, from Nexus or elsewhere, actually stand behind Shield payouts to protocol teams?
  • Third-party tracker OpenCover separately describes an older "Audit Cover" product (up to $10M, priced at 2-2.5% of cover), while Sherlock’s own current docs only describe Shield ($500k cap, score-based tiers, checked 23 Jul 2026). Is Audit Cover a retired legacy product, or a larger tier still offered alongside Shield for bigger engagements?
