Omniscia Nexera Protocol Audit
Manual Review
Manual Review
A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in Nexera Protocol's signature based call authentication system.
As the project at hand implements an authentication mechanism, intricate care was put into ensuring that the data flow within the system conforms to the specifications and restrictions laid forth within the protocol's specification.
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 an important design flaw within the system which could have had moderate ramifications to its overall operation; more details can be observed in the audit's summary.
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 a great extent, containing extensive in-line documentation throughout the contracts.
A total of 5 findings were identified over the course of the manual review of which 2 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:
