# BTC Connect

## Account Abstraction with BTC Connect

Built by [Particle Network](https://particle.network), BTC Connect is the [first account abstraction protocol for the Bitcoin ecosystem](https://blog.particle.network/btc-connect-bitcoin-account-abstraction), unifying the experience between smart accounts on Bitcoin Layer-2s and standard BTC accounts through existing wallet interfaces.

BTC Connect achieves this by allowing users to connect to your application with a native Bitcoin wallet (such as UniSat, OKX, Bitget, TokenPocket, etc.) Upon connecting, a smart account will be generated and assigned to their BTC account using custom ERC-4337 AA infrastructure deployed natively on SatoshiVM. This smart account can then be used and authenticated directly through their native Bitcoin wallet, allowing for a central interface for users across both Bitcoin Layer-1 and Bitcoin Layer-2s.

Using BTC Connect, you'll have the ability to craft a user experience akin to the example video below.

## 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.satoshivm.io/developer-guide/btc-connect.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.
