# Install Wallet UI (React Native)

## Overview

This skill helps you set up Wallet UI in your Expo React Native application. You need to choose which Solana library you are using, as the setup differs significantly.

## Choose Your Path

### 1. Modern: `@solana/kit` (Recommended)

**Use this if:**

- You are starting a new project.
- You prefer the modern, lightweight, functional API of `@solana/kit`.
- You want better tree-shaking and smaller bundle sizes.

**Instructions:**
[Open Solana Kit Guide](./solana-kit.md)

### 2. Legacy: `@solana/web3.js` (Maintenance Mode)

**Use this if:**

- You are maintaining an existing project heavily reliant on `@solana/web3.js` v1.
- You need specific legacy dependencies that haven't migrated to `@solana/kit`.
- You understand that `@solana/web3.js` is heavier and no longer the primary recommendation for new apps.
