Manual Review

A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in the staking and governance modules of Platypus Finance.

As the project at hand implements a governance module and staking implementation, 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 governance mechanisms are safe and secure under common attack vectors such as flash loans.

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 identified a major vulnerability in the governance system which could have had severe ramifications to its overall operation, however, it was conveyed ahead of time to the Platypus Finance 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 an adequate extent, however, we advise the team to streamline their comment style across the codebase for increased code legibility.

A total of 23 findings were identified over the course of the manual review of which 6 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:
