Manual Review

A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in Boson Protocol's v2.4.2 update.

As the engagement at hand represents a code delta, intricate care was put into ensuring that no security traits have been regressed and that all updates have been applied safely.

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 were unable to pinpoint any non-informational issues within the codebase and instead remarked a few optimizations as well as documentational inconsistencies that the Boson Protocol team should consider.

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, containing extensive in line documentation accompanied by technical documents meant to illustrate the various flows the system is meant to support.

A total of 5 findings were identified over the course of the manual review of which no 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.
