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.

Here is my smart contract on the blockchain
You can see it matches a software repository used to develop the code
Here is the documentation that explains what my smart contract does
Here are the tests I ran to verify my smart contract
Here are the audit(s) performed to review my code by third party experts

Answer: 81%

With 60,804 Lines of Code and only 18,522 test lines, the TtC is just 30%. However we believe the number of Lines of Code was in error. The CodeCov report indicated 80.6% coverage which is good but not great. We will score this at 81% Code examples are in the Appendix at the end of this report.. As per the SLOC, there is 30% testing to code (TtC). This score is guided by the Test to Code ratio (TtC). Generally a good test to code ratio is over 100%. However, the reviewer's best judgement is the final deciding factor. ─────────────────────────────────────────────────────────────────────────────── Language Files Lines Blanks Comments Code Complexity ─────────────────────────────────────────────────────────────────────────────── JavaScript 73 60804 7840 28082 24882 2756 ─────────────────────────────────────────────────────────────────────────────── Total 73 60804 7840 28082 24882 2756 ─────────────────────────────────────────────────────────────────────────────── Estimated Cost to Develop $789,359 Estimated Schedule Effort 12.571251 months Estimated People Required 5.578434 ─────────────────────────────────────────────────────────────────────────────── Processed 2267049 bytes, 2.267 megabytes (SI) ─────────────────────────────────────────────────────────────────────────────── C:\Users\Rex\Sync\DeFiSafety\DeFiSafety Common\Products\Processs Quality Reviews\Reviews - Copy\0.8\Forta\Flattened>cd C:\Users\Rex\Sync\DeFiSafety\DeFiSafety Common\Products\Processs Quality Reviews\Reviews - Copy\0.8\Forta\TestingEnv C:\Users\Rex\Sync\DeFiSafety\DeFiSafety Common\Products\Processs Quality Reviews\Reviews - Copy\0.8\Forta\TestingEnv>scc.exe ─────────────────────────────────────────────────────────────────────────────── Language Files Lines Blanks Comments Code Complexity ─────────────────────────────────────────────────────────────────────────────── JavaScript 22 6362 936 139 5287 128 TypeScript 7 643 108 12 523 13 JSON 5 11437 0 0 11437 0 YAML 3 80 7 4 69 0 ─────────────────────────────────────────────────────────────────────────────── Total 37 18522 1051 155 17316 141 ─────────────────────────────────────────────────────────────────────────────── Estimated Cost to Develop $539,467 Estimated Schedule Effort 10.878296 months Estimated People Required 4.405755 ─────────────────────────────────────────────────────────────────────────────── Processed 986733 bytes, 0.987 megabytes (SI) ───────────────────────────────────────────────────────────────────────────────
