Omniscia SoMee Audit

Manual Review

Manual Review

A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in the migration code and V2 token implementation of SoMee.

As the project at hand implements an ERC20 migration contract, 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 the token is fully conformant to the standards it is meant to adhere to.

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 a major vulnerability within the system which could have had severe ramifications to its overall operation, however, they were conveyed ahead of time to the SoMee team to be promptly remediated.

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 4 findings were identified over the course of the manual review of which 3 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:
