Manual Review

A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in the ERC20 token of Polytrade Finance.

As the project at hand implements an multi-EIP compliant token, intricate care was put into ensuring that the flow of funds within the system conforms to the specifications and restrictions laid forth within the EIP's specification and that all EIP interfaces are properly adhered 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. No vulnerabilities were identified, however, we pinpointed certain optimizations as well as an illogical sanitization check which we advise the Polytrade Team to remediate and further optimize the codebase.

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 1 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:
