# The Fluentbase Framework

The Fluentbase framework is used to deploy smart contracts on the Fluent L2 as well as blockchains and verifiable compute environments that compile to rWasm. It introduces an SDK and a proving system for the Fluent state transition function (STF). It is the basis for the Fluent L2 and can used to build:

* **Blended apps:** Smart contracts on the Fluent L2 written in the various programming languages that the network supports.
* **Blended execution networks:** blockchain-based networks (L2s, L3s, etc.) which simulates multiple VM targets on a shared execution layer.
* **Arbitrary compute environments:** off-chain dedicated compute environments with arbitrary logic. 

Fluentbase supports integrations to build modular blockchains including DA layers (Celestia, Avail, etc.), shared sequencers (Espresso, Nodekit), and more.

## 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.fluentlabs.xyz/learn/knowledge-base/the-fluentbase-framework.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.
