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
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
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.
