Manual Review

A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in Steer Protocol's registry and periphery contracts.

As the project at hand implements a deployment registry and periphery helper system, 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.

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 two important vulnerabilities within the system which could have had moderate ramifications to its overall operation around the registry's create2 deployment flows.

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 8 findings were identified over the course of the manual review of which 5 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:

ID	Severity	Addressed	Title
SPY-01M			Non-Standard Disable of Initializer
VRY-01M			Contradictory Documentation of Statements
VRY-02M			Non-Standard Disable of Initializer
VRY-03M			Denial-of-Service of Vault Creation
VRY-04M			Inexistent Handling of Creation Failure
