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

Platform Rules

Please review the Sherlock Bug Bounty Platform Rules before submitting any vulnerability.

Known Issues and Acceptable Risks

  • In the liquidation system, we allow liquidators to liquidate a user if they were insolvent before. The nonce should not be changed from that time (essentially, the user's positions should remain unchanged during this period). If the user adds funds to become solvent, the liquidator can still liquidate the user and return the extra funds.
