# Audit Certik
Phina Network has successfully completed a professional security audit by **CertiK**, ensuring that our smart contracts and ecosystem infrastructure follow industry-leading security standards. The audit reduces common vulnerabilities, strengthens code quality, and increases transparency — helping users interact with Phina PayCard, Metaverse assets, and on-chain services with greater confidence.
> ⚠️ **Note:** Security audits significantly lower risks but cannot eliminate them completely. Users should always exercise caution when engaging with crypto assets.

## 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://phina-network.gitbook.io/phn/audit-certik.md?ask=&goal=
```
`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.
