# Installation

> Install Starkzap and its dependencies

## Installation

Install Starkzap using npm or yarn:

```bash theme={null}
npm install starkzap
```

or

```bash theme={null}
yarn add starkzap
```

<Info>
  Building for React Native/Expo? Use [React Native Integration](/build/starkzap/react-native) and install `starkzap-native` instead of using `starkzap` directly in your mobile app.
</Info>

### Dependencies

The SDK depends on:

* [`starknet`](https://www.npmjs.com/package/starknet) (v9+) - Starknet.js core library

This will be installed automatically when you install `starkzap`.

#### Peer dependencies by feature

All peer dependencies are **optional** to keep the package lean. Install only what you need:

```bash theme={null}
# Ethereum bridging
npm install ethers

# Solana bridging
npm install @solana/web3.js @hyperlane-xyz/sdk @hyperlane-xyz/registry @hyperlane-xyz/utils

# Cartridge Controller (only for Web)
npm install @cartridge/controller

# Confidential transfers
npm install @fatsolutions/tongo-sdk

# React Native / Expo (use starkzap-native instead of starkzap)
npm install starkzap-native react-native-get-random-values fast-text-encoding @ethersproject/shims buffer
```

## Next Steps

Once installed, configure the SDK:

1. Set up [Configuration](/build/starkzap/configuration) for networks, RPC providers, and optional features
2. If you are building a mobile app, follow [React Native Integration](/build/starkzap/react-native) for `starkzap-native` + Metro setup
3. Then check out the [Quick Start Guide](/build/starkzap/quick-start) to get your first wallet integration working in minutes
