Horizon Protocol Smart Contracts: Program info

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

• Theoretical vulnerabilities without any proof or demonstration
• Old compiler version
• The compiler version is not locked
• Vulnerabilities in imported contracts
• Code style guide violations
• Redundant code
• Gas optimizations
• Best practice issues

• 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• Please do NOT publish/discuss bugs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 HackenProof ADDRESS (in case of violation, no bounty can be awarded)
• Provide detailed but to-the point reproduction steps
