# Introduction

[Leather](https://leather.io/) empowers developers to build apps with the [Bitcoin](https://bitcoin.org/) and [Stacks](https://stacks.co/) blockchains, tapping into the multilayered Bitcoin economy.

Connect and interact with user wallets via [the Leather browser extension](https://leather.io/install) using our suite of simple JavaScript methods.

## Provider object

The Leather extension injects a global object that can be used to call its API. 

Look for the presence of `LeatherProvider` to see if the Leather is installed:

```typescript
if (window.LeatherProvider) // Leather is installed 🎉
```

This object implements the `.request` method standard from [Modern Wallet APIs proposal](https://github.com/stacksgov/sips/pull/166). 

Simply provide the method name and any necessary parameters, such as `sendTransfer` for [sending Bitcoin](https://leather.gitbook.io/developers/bitcoin-methods/sendtransfer):

```
const response = await window.LeatherProvider?.request("sendTransfer", {
  recipients: [
    {
      address: "tb1qkzvk9hr7uvas23hspvsgqfvyc8h4nngeqjqtnj",
      amount: "10000",
    }
  ]);
```
