# Hardware Wallets with Nethereum

Sign from a Ledger or Trezor without the key leaving the device

## What this does

Keeping a private key in your application is a risk; keeping it on a device that signs and hands back the result is not the same thing. This connects Ledger and Trezor hardware wallets to your C# code so transactions get signed on the device. Reach for it when the key should never sit in your app.

### Top 3 things it does for you

- Sign a transaction with a Ledger
- Sign a transaction with a Trezor
- Connect a hardware wallet to a .NET app
