Hacken Service Summary
Hacken performed the blockchain security testing for OneLedger. The project scope was:
1. Architecture Analysis and Threat Modelling
2. Manual and Automated Code Review
3. Smart Contract Audit
4. Manual Validators testing
During the project, consultants found some security issues and the Hacken engineers made recommendations on how to fix them.
Security engineers performed threats analysis, architecture review and prepared a security testing plan covering all the potential security issues.
The smart contract within the scope was manually reviewed and analyzed with static analysis tools. Security engineers found some issues during the initial smart contract audit.
The customer redesigned the smart contract and fixed all found issues. However, low to medium issues were found during the secondary smart contract audit. The customer has already begun working on fixing the medium to high priority issues as recommended by our team.
According to the review, the Hacken auditors recommend the OneLedger Protocol to fix security issues to achieve a secure state. The original code of OneLedger was noted to be of very good quality. The OneLedger team has already started working on the bug fixes, and after the fixes are made, the Hacken team will perform a review of fixes and re-test critical components of the protocol.
