{% hint style="info" %}
Polygon network now supports MEV protection. This feature affects the eth\_sendRawTransaction method. Once enabled, each transaction submitted via sendRawTransaction will be charged at 250,000 RU per request.

The fee exists because MEV protection in the Polygon ecosystem is exclusively provided by the Polygon official as a paid service — there is no alternative third-party option available. Although this comes with an additional cost, the feature provides 100% protection against MEV attacks, safeguarding traders from sandwich attacks, front-running, and other malicious activities. It is also backed by Polygon's official endorsement, ensuring reliability and security.

## 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.blockpi.io/build/api-reference/polygon/eth_sendrawtransaction.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.
