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 have found that the codebase contains 6 high-risk issues that require prompt attention. In addition, we have identified other non-critical issues as well as recommendations and notes that should be considered. The Burrowland, Ref-Dcl, Ref-Exchange team has addressed these issues promptly. It is important to note that our audit covers only the final reported versions of the codebase. Any subsequent updates would require a re-evaluation.
