Manual Review

A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in Nexera's ODC implementation update.

As the project at hand represents a code delta, intricate care was put into ensuring that the flow of funds within the system conforms to the specifications and restrictions laid forth within the protocol's specification and that all previously established security traits of the system continue to apply.

We validated that all state transitions of the system occur within sane criteria and that all rudimentary formulas within the system execute as expected. We pinpointed medium-severity vulnerabilities within the system's pausable implementation which could have had moderate ramifications to its overall operation; for more information, kindly consult the audit report's summary as well as the dedicated medium-severity exhibits.

Additionally, the system was investigated for any other commonly present attack vectors such as re-entrancy attacks, mathematical truncations, logical flaws and ERC / EIP standard inconsistencies. The documentation of the project was satisfactory to the extent it need be.

A total of 11 findings were identified over the course of the manual review of which 5 findings concerned the behaviour and security of the system. The non-security related findings, such as optimizations, are included in the separate Code Style chapter.

The finding table below enumerates all these security / behavioural findings:

ID	Severity	Addressed	Title
ERC-01M			Improper Allowance Bypass
FEG-01M			Inexistent Override of Burn / Mint Capabilities
FEP-01M			Inexistent Override of Burn / Mint Capabilities
FEP-02M			Insufficient Override of Omnichain Transfer Capabilities
OEC-01M			Improper Allowance Bypass
