# L2 Precompiles

A special type of smart contract built directly into the EVM that executes common cryptographic operations with greater efficiency than contracts written in high-level languages like Solidity

Note that the support for these precompiles may change as the Zircuit proof system evolves. They should be used with caution. If you have any questions, please reach out via discord.

# Agent Instructions: 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:

```
GET https://docs.zircuit.com/addresses/precompiles.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
