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)
- Attacks requiring the exploitation of previously-discovered bugs. If a bug report covers a known issue, it may be rejected together with proof of the issue being known before escalation of the bug report
Smart Contracts and Blockchain
- Underlying protocols and services developed and maintained by third-party
- Incorrect data supplied by third-party oracles
- Not to exclude oracle manipulation/flash loan attacks
- Gas optimisation issues
- 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
- Self-XSS
- CSRF with no security impact (logout CSRF, change language, etc.)
- Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”)
- Server-side information disclosure such as IPs, server names, and most stack traces
- Vulnerabilities used to enumerate or confirm the existence of users or tenants
- Vulnerabilities requiring unlikely user actions
- URL Redirects (unless combined with another vulnerability to produce a more severe vulnerability)
- Lack of SSL/TLS best practices
- DDoS vulnerabilities
- Attacks requiring privileged access from within the organization
- Feature requests
- Best practices
- Vulnerabilities primarily caused by browser/plugin defects
- Any vulnerability exploit requiring CSP bypass resulting from a browser bug
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
