# Supply Cap

## Introduction to Supply Cap

In Tectonic, securing users’ assets is always our top priority. Hence, we have deployed a supply cap to limit supply to selected markets with regard to the available on-chain liquidity of the underlying asset. When the supply of the market is equal or larger than the configured supply limit, users will not be able to add additional supply to the market. However, interest will continue to accrue to the current suppliers.

For detailed information on the supply cap parameters, please refer to the [market parameter table](https://tectonic.gitbook.io/docs/protocol/money-market-parameters).

Here are two scenarios regarding the supply cap implementation:

**Scenario A: Total supply has hit the supply cap**

When the total supply > supply cap and supply cap > 0, all supply buttons for that market will be disabled and the supply modal cannot be opened. There will also be an error message to inform you with such a condition: “You are unable to deposit your tokens as the maximum amount that can be supplied to this market has been reached.”

**Scenario B: Total supply has not hit the supply cap, but your input amount will exceed supply cap**

When your input supply amount > supply cap and supply cap > 0, the supply button in the modal will be disabled and you can no longer supply tokens into that market. There will also be an error message to inform you with such a condition: “You are unable to deposit your tokens as the maximum amount that can be supplied to this market has been reached.”\
\
Alternatively, you may choose to lower your supply amount so that the total supply amount will not exceed the supply cap.

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://tectonic.gitbook.io/docs/protocol/supply-cap.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.
