Manual Review

A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in Alliance Block's Bridge implementation.

As the project at hand implements the EIP-2535 Diamond standard, 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 cross-implementation interactions are sound and safe.

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 certain reward-related issues within the system which can cause fees to be distributed unfairly and we strongly urge the Alliance Block team to deal with those as soon as possible.

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 a good extent.

A total of 11 findings were identified over the course of the manual review of which 4 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:
