Very simply, the audit looks for the following declarations from the developer's site. With these declarations, it is reasonable to trust the smart contracts.

This section looks at the code deployed on the relevant chain that gets reviewed and its corresponding software repository. The document explaining these questions is here.
1. Are the smart contract addresses easy to find? (%)
They can be found at https://docs.alternity.finance/faq/technical-resources .
2. How active is the primary contract? (%)
Contract Stability Pool is used barely 10 times a week, as indicated in the Appendix.
3. Does the protocol have a public software repository? (Y/N)
Location: https://github.com/0xAlternity/dev
4. Is there a development history visible? (%)
With 3,149 commits and 54 branches, this is a very healthy repository. It may be that many of these commits came directly from the Liquity repository. There are a clear 64 commits made by Alternity. We will give them the 100%.
5. Is the team public (not anonymous)?
The team appears to be anonymous.
This section looks at the software documentation. The document explaining these questions is here.
6. Is there a whitepaper? (Y/N)
Location: https://docs.alternity.finance/
7. Is the protocol's software architecture documented? (Y/N)
Software architecture.
8. Does the software documentation fully cover the deployed contracts' source code? (%)
There is software documentation evident. The documentation may not be complete, but much is covered. 80% score given.
9. Is it possible to trace the documented software to its implementation in the protocol's source code? (%)
Documentation lists all the functions and describes their functions but does not supply actual traceability.
10. Has the protocol tested their deployed code? (%)
The GitHub repository is a direct clone from Liquity. The details of the fork differences are described. However the repo clearly reflects the code that was deployed. The repo includes tests. The test code ratio is 278%, therefore 100%.
11. How covered is the protocol's code? (%)
The code coverage indicator in the GitHub links to Coveralls which indicates 97%
12. Does the protocol provide scripts and instructions to run their tests? (Y/N)
Location: https://github.com/0xAlternity/dev#running-tests
13. Is there a detailed report of the protocol's test results?(%)
There is a Coveralls for a test report.
14. Has the protocol undergone Formal Verification? (Y/N)
This protocol has not undergone formal verification.
15. Were the smart contracts deployed to a testnet? (Y/N)
Alternity is clearly deployed to a testnet.
This section looks at the 3rd party software audits done. It is explained in this document.
16. Is the protocol sufficiently audited? (%)
The GitHub repository is a direct clone from Liquity. The data detailing the fork is available. The Liquity audits give a 100% score. Since some of the changed code is clearly unaudited, we will reduce this to 80%
17. Is the bounty value acceptably high (%)
There is a Hats Finance bug bounty of .
This section covers the documentation of special access controls for a DeFi protocol. The admin access controls are the contracts that allow updating contracts or coefficients in the protocol. Since these contracts can allow the protocol admins to "change the rules", complete disclosure of capabilities is vital for user's transparency. It is explained in this document.
18. Is the protocol's admin control information easy to find?
Admin control information was documented at this location. This was quick to find.
19. Are relevant contracts clearly labelled as upgradeable or immutable? (%)
The relevant contracts are clearly identified as immutable, as identified here.
20. Is the type of smart contract ownership clearly indicated? (%)
Ownership is clearly indicated in this location. as immutable.
21. Are the protocol's smart contract change capabilities described? (%)
Smart contract change capabilities are not possible as all contracts are immutable.
22. Is the protocol's admin control information easy to understand? (%)
This information is not in software specific language. The statement "As a protocol, Alternity is non-custodial, immutable, and governance-free." is very clear,
23. Is there sufficient Pause Control documentation? (%)
This protocol's pause control is not documented.
24. Is there sufficient Timelock documentation? (%)
This protocol has no timelock documentation as it is immutable.
25. Is the Timelock of an adequate length? (Y/N)
This protocol has no timelock documentation as it is immutable.
This section goes over the documentation that a protocol may or may not supply about their Oracle usage. Oracles are a fundamental part of DeFi as they are responsible for relaying tons of price data information to thousands of protocols using blockchain technology. Not only are they important for price feeds, but they are also an essential component of transaction verification and security. These questions are explained in this document.
26. Is the protocol's Oracle sufficiently documented? (%)
The protocol's oracle source is clearly documented at this location. The contracts dependent are not identified. There is relevant software function documentation.
27. Is front running mitigated by this protocol? (Y/N)
This protocol does not document front running mitigation techniques.
28. Can flashloan attacks be applied to the protocol, and if so, are those flashloan attack risks mitigated? (Y/N)
This protocol does not documents flashloan countermeasures.
