JOJO Smart Contracts

Company: JOJO
This program is active now
Program info

JOJO is a decentralised perpetual contract based on a 100% on-chain perpetual contract ledger and an off-chain matching system which could provide deeper liquidity than AMM perp contracts and a safer trading experience than CLOB perp contracts.

Focus Area

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
  • Permanent freezing of funds
  • Unauthorized transaction
  • Transaction manipulation
  • Attacks on logic (behavior of the code is different from the business description)
  • Reentrancy
  • Reordering
  • Over and underflows
  • Unable to match orders
  • Risk parameters being changed by non-owner address

OUT OF SCOPE: SMART CONTRACT VULNERABILITIES

  • Theoretical vulnerabilities without any proof or demonstration
  • Stealing or losing funds of Admin, Insurance, order sender, and funding rate keeper accounts
  • Oracle Failed
  • Old compiler version
  • The compiler version is not locked
  • Vulnerabilities in imported contracts
  • Code style guide violations
  • Redundant code
  • Gas optimizations
  • Best practice issues

Program Rules

  • 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

Disclosure Guidelines

  • 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  • Please do NOT publish/discuss bugs

Eligibility and Coordinated Disclosure

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
