DESCRIPTION
The target of this audit is the private code repository of CoboTokenization of Cobo. CoboTokenization is a sophisticated, upgradeable ERC20 token implementation with rolebased access control, and can be deployed on different chains with same address via the contract ProxyFactory.
Please refer to the report for the detailed audit scope.
Our audit methodology employs automated vulnerability scans, manual verification, and business logic analysis to uncover potential security issues coupled with gas and code quality optimization recommendations.
In summary, we did not find any critical issues within the audited codebase. However, we have identified some non-critical issues that should be addressed. Additionally, we have put forth recommendations and notes that should be taken into consideration. It is important to note that the scope of our audit was strictly limited to the specific code versions mentioned in the report. Any updates made subsequent to our review would require a re-evaluation.
