Proof-of-Concept requirements

  • POC-1Critical and High reports must include a runnable PoC demonstrating the claimed impact end-to-end.
  • POC-2The PoC must state its environment (fork block, commit, build) and must never be executed against production.

Testing restrictions

  • TEST-1Testing against production systems or mainnet deployments is prohibited; use local forks or staging.
  • TEST-2Phishing, social engineering and physical attacks are prohibited.
  • TEST-3Denial-of-service attacks against project infrastructure are prohibited.

Out-of-scope & exclusions

A closure as out of scope must cite one of these ids.

  • EXCL-1Missing security headers or best practices without demonstrated impact.
  • EXCL-2Attacks requiring physical access to a victim's unlocked device.
  • EXCL-3Rate-limiting or brute-force issues on non-authentication endpoints.

Policies

Duplicate policy

The first report that identifies a root cause is eligible. Later reports sharing the same root cause are duplicates unless they demonstrate a materially higher impact.

Known-issues policy

Issues in published audits or recorded as known-issue commitments before the submission timestamp are ineligible.

Disclosure · 30-day embargo

Public disclosure requires approval from both parties after the fix is deployed and verified.

Mediation · 7-day window

Either decision may be escalated to an independent platform mediator within 7 days of the project's final decision.

Payment · USDC on Ethereum

Recognition only: this program pays no monetary rewards. Valid findings receive a verified acknowledgement and credit on the researcher's Proofline profile.
