Security Audit Report for Cobo's CoboTokenization

The target of this audit is the code repository of CoboTokenization of Cobo. CoboTokenization consists of two upgradeable systems, CoboERC20 and Fund. The CoboERC20 system includes contracts CoboERC20 and CoboERC20Wrapper, where CoboERC20 provides controlled ERC-20 issuance and transfer controls and CoboERC20Wrapper handles underlying asset wrapping and unwrapping with reconciliation-based recovery minting. The Fund system includes contracts CoboFundOracle, CoboFundToken, and CoboFundVault, which maintain APR and compute NAV, manage share subscriptions and asynchronous redemptions, and execute custody settlement payouts. The overall security model relies on role separation and whitelist and blacklist checks on critical execution paths.

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 identify any potential issues within the audited codebase. However, we have some recommendations and notes that should be considered to further enhance the protocol's quality, security, and reliability. With no potential issues identified, the project demonstrates a relatively high level of security. It should also be noted that the scope of our audit was strictly limited to the specific code versions detailed in the report. Any updates subsequent to our review would necessitate a re-evaluation.
