Out of scope

Program's Out of Scope information

The following vulnerabilities are excluded from the rewards for this bug bounty program:

  • Attacks that the reporter has already exploited themselves, leading to damage
  • Attacks requiring access to leaked keys/credentials
  • Attacks requiring access to privileged addresses (governance, strategist)

Smart Contracts and Blockchain

  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks
  • Basic economic governance attacks (e.g. 51% attack)
  • Lack of liquidity
  • Best practice critiques
  • Sybil attacks
  • Centralization risks

Websites and Apps

  • Theoretical vulnerabilities without any proof or demonstration
  • Attacks requiring physical access to the victim device
  • Attacks requiring access to the local network of the victim
  • Reflected plain text injection ex: url parameters, path, etc.
    • This does not exclude reflected HTML injection with or without javascript
    • This does not exclude persistent plain text injection
  • Self-XSS
  • Captcha bypass using OCR without impact demonstration
  • CSRF with no state modifying security impact (ex: logout CSRF)
  • Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”) without demonstration of impact
  • Server-side non-confidential information disclosure such as IPs, server names, and most stack traces
  • Vulnerabilities used only to enumerate or confirm the existence of users or tenants
  • Vulnerabilities requiring un-prompted, in-app user actions that are not part of the normal app workflows
  • Lack of SSL/TLS best practices
  • DDoS vulnerabilities
  • Feature requests
  • Issues related to the frontend without concrete impact and PoC
  • Best practices issues without concrete impact and PoC
  • Vulnerabilities primarily caused by browser/plugin defects
  • Leakage of non sensitive api keys ex: etherscan, Infura, Alchemy, etc.
  • Any vulnerability exploit requiring browser bugs for exploitation. ex: CSP bypass

The following activities are prohibited by this bug bounty program:

  • Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
  • Any testing with pricing oracles or third party smart contracts
  • Attempting phishing or other social engineering attacks against our employees and/or customers
  • Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
  • Any denial of service attacks
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
