# Sats Connect

[**Sats Connect**](https://github.com/secretkeylabs/sats-connect) is a simple javascript library that connects apps to **Bitcoin**, **Spark**, **Starknet**, **Stacks**, and other **Bitcoin Layer 2 wallets** like [**Xverse**](https://www.xverse.app/). 

It’s already powering apps across the BitcoinFi ecosystem, with close to **2 million downloads** — making it one of the most widely used ways for developers to integrate Bitcoin wallets today.

## ✨ What you can do with Sats Connect

Developers building on Bitcoin and its L2s can use Sats Connect to interact directly with users’ wallets:

* 🔑 **Retrieve wallet addresses** for Bitcoin, Spark, Starknet, Stacks, and more
* ✍️ **Request signatures** of messages for authentication or verification
* 🔗 **Sign & send transactions**:
  * Bitcoin PSBTs
  * Spark BTC & token transfers
  * Starknet & Stacks transfers & contract calls
* :frame\_photo::black\_square\_button:🪙 **Ordinals, Runes & BRC-20**:
  * Track balances across assets
  * Transfer tokens and inscriptions
  * Inscribe sats with arbitrary content, create and mint tokens

### 🛠️ Why Sats Connect?

* **Wallet-first** – every interaction happens directly in the user’s wallet, with explicit approval
* **Bitcoin-native & multi-asset** – supports Bitcoin L1 (BTC, Ordinals, Runes, BRC-20) as well as emerging L2s like Spark, Starknet, and Stacks
* **Comprehensive toolkit** – from simple address retrieval to advanced features like signing PSBTs, transferring Spark tokens, or inscribing Ordinals
* **Battle-tested** – trusted by leading BitcoinFi apps, with close to **2M downloads** and a growing developer ecosystem

## 🚀 Get started

To get started, import `sats-connect` into your project.

```sh
npm install sats-connect@4.2.x
```

Then request a [wallet connection ](https://docs.xverse.app/sats-connect/connecting-to-the-wallet/connect-to-xverse-wallet)— and explore the docs to unlock the full Bitcoin stack: Bitcoin L1, Spark, Starknet, Stacks, and the assets built on top.

## ⚡ Power your Bitcoin apps with plug-and-play infra

Sats Connect lets your app connect directly to users’ wallets.\
The [Xverse API](https://docs.xverse.app/api) gives you **plug-and-play access to Bitcoin data and infrastructure** — Ordinals, Runes, mempool, balances, transactions, collections, and more — without running your own nodes or indexers.

Together, they remove the heavy lifting so you can focus on building the next generation of Bitcoin apps.
