# Requirements

This page lists the environment requirements for `@ledgerhq/ledger-wallet-provider`. The SDK communicates directly with Ledger hardware signers over USB (Web HID API) and Bluetooth (Web Bluetooth API), so it requires a browser environment where those APIs are available. It cannot run in Node.js or any server-side environment.

## Platform requirements

- ES2020+ support
- Modern bundler (Vite, Webpack 5+, etc.)
- Browser environment (no Node.js server-side execution)
- Web HID API support (for USB connections)
- Web Bluetooth API support (for Bluetooth connections)

> **Note:** Mobile browsers are not supported because Web HID and Web Bluetooth APIs are not available on iOS or Android.

## Browser support

- **Desktop**: Chrome 89+, Firefox 89+, Safari 14.1+, Edge 89+
- **Mobile**: Not supported (Web HID and Web Bluetooth APIs are not available)
