# How to Support Bitcoin Network?

<figure><img src="/files/OdBDOaLPDNxGr07MRK69" alt=""><figcaption></figcaption></figure>

Satoshi ProtocolBigFat uses [Satoshi Protocol](https://satos.network/) technology, which is built using Near Chain's Chain Abstraction, creating a Bitcoin-like L2 implementation.While [Satoshi Protocol ](https://satos.network/)may seem like a Bitcoin L2, it is actually quite different from most L2 solutions.

#### The key points: <a href="#the-key-points" id="the-key-points"></a>

1. ​[Satoshi Protocol](https://satos.network/) naturally integrates all Near Chain dApps, meaning there’s no need for additional dApp ecosystem building—users already have access to a complete Near ecosystem.
2. ​[Satoshi Protocol](https://satos.network/) allows Bitcoin users to directly sign transactions using their Bitcoin wallet, without needing to create a new wallet.
3. Instant withdrawals: Thanks to Near Chain's Chain Abstraction, [Satoshi Protocol](https://satos.network/) (and BigFat) enables Bitcoin users to complete BTC transaction withdrawals in seconds.

## 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.unifat.xyz/product-introduction/ai-agent-launchpad/how-to-support-bitcoin-network.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.
