Omniscia Steer Protocol Audit
Manual Review
Manual Review
A thorough line-by-line review was conducted on the codebase to identify potential malfunctions and vulnerabilities in Steer Protocol's Uniswap V4 liquidity manager
As the project at hand implements a liquidity manager, 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 as well as the specifications present in Uniswap V4.
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 multiple significant vulnerabilities within the system which could have had severe ramifications to its overall operation; for more information, kindly consult all non-informational exhibits within the audit report as well as the audit report's summary.
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 24 findings were identified over the course of the manual review of which 11 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:

| LMV-01M |  | | Non-Standard Disable of Initialization |
| LMV-02M | | | Improper Deviation of Logic |
| LMV-03M | |  | Inexistent Validation of Fee Values |
| LMV-04M | | | Rounding of Fee Distribution |
| LMV-05M | | | Incorrect Evaluations of Vault Totals |
| LMV-06M | | | Inexistent Prevention of Overlapping Tick Ranges |
| LMV-07M | | | Inexistent Utilizations of Currency Metadata |
| LMV-08M |  | | Re-Entrancy Fee Duplication Vulnerability |
