# Max Gas Limit

To manage gas costs, we have set a <mark style="color:blue;">**max gas limit**</mark> called `maxGasForMatching`, ensuring that matching transactions are executed efficiently and remain cost-effective by preventing excessive gas consumption.

1. The initial state: Supply 1 is 300 USDC, and supplies 2 through 10 are 10 USDC each.
2. When borrow 11 is requested, priority is given to supply 1.
3. After matching 300 USDC, followed by 10 USDC in each of the next 6 iterations, the gas limit of `maxGasForMatching` is reached.
4. The matching engine then stops.
5. The remaining 30 USDC falls back to the underlying protocol.

## 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.evoq.finance/advanced-mechanism/matching-engine/max-gas-limit.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.
