Reward Amounts

Critical

  • 1,000,000 USDC maximum payout
  • Payout shall not exceed 10% of funds at risk at time of submission

Actual reward amounts will be decided upon vulnerability validation and severity assessment by Sherlock, up to the caps listed above. Lower-severity issues (e.g. Low or Informational) are not eligible for rewards under this program.

Severity Criteria

Critical Definition

  • Definite and significant loss of funds without limitations of external conditions
  • Definite and significant freezing of funds for >1 year without limitations of external conditions
  • Only vulnerabilities in core contracts qualify for the Critical severity

General Notes

  • Sherlock’s Criteria for Issue Validity guide (used in Sherlock audit contests) can be a helpful resource for more context on out-of-scope issues, etc. but nothing in the guide
    should overrule the definitions above
  • A coded Proof of Concept (POC) with instructions to run the POC is required
  • If the protocol team has the ability to take measures (upgrade the
    contract, pause the contract, etc.) against an exploit, the potential
    damage is limited to a 1-hour exploit period before it is assumed that
    the protocol team takes measures to prevent further damage
