Omniscia Nexera Audit

Manual Review

Manual Review

A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in Nexera's reference EIP-7208 implementation.

As the project at hand implements a novel EIP, intricate care was put into ensuring that the standards implemented within the system conform to the specifications and restrictions laid forth within the EIP'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 several discrepancies within the system one of which could have had moderate ramifications to its overall operation; we urge the Nexera team to promptly evaluate and address all non-informational exhibits within the audit report.

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 an exemplary extent, accompanied by extensive documentation in the EIP itself.

A total of 13 findings were identified over the course of the manual review of which 7 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:
