# Audits

Tokan Exchange is a THENA fork. THENA's codebase was adapted from Velodrome codebase, which was lifted directly from the Solidly smart contracts which were made open source in March 2022.

THENA was completely audited by PeckShield on March 25, 2023:

The original Solidly AMM has been audited by PeckShield, which revealed 5 low-severity and 1 informal findings. There have been no security-related incidents involving Solidly smart contracts since their deployment on Fantom in February 2022.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tokan.exchange/contracts/audits.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
