Policies

Duplicate policy

The first report that identifies a root cause is eligible. Later reports sharing the same root cause are duplicates, even when they describe a different attack path, unless they demonstrate a materially higher impact.

Known-issues policy

Issues listed in published audits or recorded as known-issue commitments before the submission timestamp are ineligible. Commitments may be revealed during a dispute.

Disclosure · 30-day embargo

Public disclosure requires approval from both parties after the fix is deployed and verified. Default embargo: 30 days after fix.

Mediation · 7-day window

Either decision may be escalated to an independent platform mediator within 7 days of the project's final decision. The mediator publishes a reasoned decision to both parties.

Payment · USDC on Polygon · KYC

Rewards are paid in USDC on Polygon within 30 days of retest. KYC is required for payouts above $10,000.
