IN-SCOPE: SMART CONTRACT VULNERABILITIES

We are looking for evidence and reasons for incorrect behavior of the smart contract, which could cause unintended functionality:

  • Stealing or loss of funds
  • Unauthorized transaction
  • Transaction manipulation
  • Attacks on logic (behavior of the code is different from the business description)
  • Reentrancy
  • Reordering
  • Over and underflows

OUT OF SCOPE: SMART CONTRACT VULNERABILITIES

  • 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
  • Spam attacks
  • Centralization risks
  • Issues without proof of concept are out of scope

The following known issues are considered to be out of scope:

  • Gas griefing specifically by spam attacks
  • Gas griefing specifically in SuperApp termination callbacks
  • Re-entrance issues:
  • SuperApp framework allowing callbacks
  • Super Token is ERC-777, which also allows callbacks
  • Avoid using web application scanners for automatic vulnerability searching which generates massive traffic
  • Make every effort not to damage or restrict the availability of products, services, or infrastructure
  • Avoid compromising any personal data, interruption, or degradation of any service
  • Don’t access or modify other user data, localize all tests to your accounts
  • Perform testing only within the scope
  • Don’t exploit any DoS/DDoS vulnerabilities, social engineering attacks, or spam
  • Don’t spam forms or account creation flows using automated scanners
  • In case you find chain vulnerabilities we’ll pay only for vulnerability with the highest severity.
  • Don’t break any law and stay in the defined scope
  • Any details of found vulnerabilities must not be communicated to anyone who is not a HackenProof Team or an authorized employee of this Company without appropriate permission
  • Do not discuss this program or any vulnerabilities (even resolved ones) outside of the program without express consent from the organization
  • No vulnerability disclosure, including partial is allowed for the moment.
  • Please do NOT publish/discuss bugs

We are happy to thank everyone who submits valid reports which help us improve the security. However, only those that meet the following eligibility requirements may receive a monetary reward:

  • You must be the first reporter of a vulnerability.
  • The vulnerability must be a qualifying vulnerability
  • Any vulnerability found must be reported no later than 24 hours after discovery and exclusively through hackenproof.com
  • You must send a clear textual description of the report along with steps to reproduce the issue, include attachments such as screenshots or proof of concept code as necessary.
  • You must not be a former or current employee of us or one of its contractor.
  • ONLY USE YOUR HackerProof ADDRESS (in case of violation, no bounty can be awarded)
  • Provide detailed but to-the point reproduction steps
