Security Audit Report for Multichain veMULTI Contracts

Multichain is the ultimate Router for web3. It is an infrastructure developed for arbitrary cross-chain interactions. The core contracts covered in this audit include the veMULTI contracts in the code repository. The iterative audit covers the code in the initial version, as well as subsequent versions to fix discovered issues, as detailed in our audit report. Please note that external dependencies are assumed reliable and are therefore excluded from the 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 nine non-critical issues that should be addressed. Additionally, we have put five recommendations to further strengthen the code logic. 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.
