Security Audit
September 6, 2024
Version 1.0.0
Presented by 0xMacro
This document includes the results of the security audit for Infinex's smart contract code as found in the section titled ‘Source Code’. The security audit was performed by the Macro security team on September 6, 2024.
The purpose of this audit is to review the source code of certain Infinex Solidity contracts, and provide feedback on the design, architecture, and quality of the source code with an emphasis on validating the correctness and security of the software in its entirety.
Disclaimer: While Macro’s review is comprehensive and has surfaced some changes that should be made to the source code, this audit should not solely be relied upon for security, as no single audit is guaranteed to catch all possible bugs.
No issues or discrepancies were identified within the defined scope of this audit.
Our understanding of the specification was based on the following sources:
The changes audited rely on the following assumptions specifically.
authorizedKeepers are trusted actors that will not execute the claim() function maliciously.authorizedKeepers should verify the input validity, the contract will verify the replayability with an arbitrary input nonce.owner can withdraw the governance points tokens from the contract at discretion if needed.The following source code was reviewed during the audit:

69973d8c98a7a13a36ec73ef72463a156c9112ac
Specifically, we audited the following contracts:
| Source Code | SHA256 |
|---|---|
| ./src/access/KeeperManager.sol |
|
| ./src/forwarder/ERC2771Base.sol |
|
| ./src/governance/GPDistributor.sol |
|
And, the following for the Points update:
| Source Code | SHA256 |
|---|---|
| ./src/governance/GovernancePoints.sol |
|
Note: Currently the referenced repository is private, but there are plans to make it public in the future.
We quantify issues in three parts:
This third part – the severity level – is a summary of how much consideration the client should give to fixing the issue. We assign severity according to the table of guidelines below:
| Severity | Description |
|---|---|
|
(C-x) Critical |
We recommend the client must fix the issue, no matter what, because not fixing would mean significant funds/assets WILL be lost. |
|
(H-x) High |
We recommend the client must address the issue, no matter what, because not fixing would be very bad, or some funds/assets will be lost, or the code’s behavior is against the provided spec. |
|
(M-x) Medium |
We recommend the client to seriously consider fixing the issue, as the implications of not fixing the issue are severe enough to impact the project significantly, albiet not in an existential manner. |
|
(L-x) Low |
The risk is small, unlikely, or may not relevant to the project in a meaningful way. Whether or not the project wants to develop a fix is up to the goals and needs of the project. |
|
(Q-x) Code Quality |
The issue identified does not pose any obvious risk, but fixing could improve overall code quality, on-chain composability, developer ergonomics, or even certain aspects of protocol design. |
|
(I-x) Informational |
Warnings and things to keep in mind when operating the protocol. No immediate action required. |
|
(G-x) Gas Optimizations |
The presented optimization suggestion would save an amount of gas significant enough, in our opinion, to be worth the development cost of implementing it. |
