# Security

Beyond smart contract audits, the Altitude protocol employs a variety of additional security measures.

## Threat monitoring

We've implemented Hypernative's real-time threat monitoring system. Hypernative monitors for suspicious activity, potential exploits, and abnormal transaction patterns across the protocol. If a threat is detected, automated responses can pause affected functions to protect user funds. This provides an additional security layer beyond smart contract audits.

For more details, see the announcement:

## Rate limiter

The rate limit is a security consideration that can limit the impact of any possible exploits. It controls how much can be extracted from the protocol at any time. It works by setting both:

* an amount that can be extracted and
* the period this amount can be extracted within

The mechanism of the rate limit allows the entire amount to be withdrawn at the beginning of the period and with time passing the amount is increasing linearly.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.altitude.fi/smart-contracts/security.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.
