## Install the Cosmos Ledger application
|
||||
|
||||
Installing the `Cosmos` application on your ledger device is required before you can use either [Lunie](#lunie-io-+-ledger-nano) or [`gaiacli`](gaia-cli-+-ledger-nano). To do so, you need to:
|
||||
|
||||
1. Install [Ledger Live](https://shop.ledger.com/pages/ledger-live) on your machine.
|
||||
2. Using Ledger Live, [update your Ledger Nano S with the latest firmware](https://support.ledger.com/hc/en-us/articles/360002731113-Update-device-firmware).
|
||||
3. On the Ledger Live application, navigate to the `Manager` menu .
|
||||
|
||||
4. Connect your Ledger Nano device and allow Ledger Manager from it.
|
||||
5. On the Ledger Live application, Search for `Cosmos`.
|
||||
|
||||
6. Install the Cosmos application by clicking on `Install`.
|
||||
|
||||
::: tip
|
||||
To see the `Cosmos` application when you search for it, you might need to activate the `Developer Mode`, located in the Experimental features tab of the Ledger Live application.

## Lunie.io + Ledger Nano
|
||||
|
||||
**Note: You need to [install the Cosmos app](#install-the-cosmos-ledger-application) on your Ledger Nano before using following this section**
|
||||
|
||||
1. Connect your Ledger device to your computer, unlock it with the PIN and open the Cosmos app.
|
||||
2. Open [https://app.lunie.io](https://app.lunie.io/existing) in your web browser (latest version of [Brave](https://brave.com/) preferred).
|
||||
3. Choose `Sign in with Ledger Nano S`.
|
||||
|
||||
4. Make sure your Ledger device is unlocked and with the Cosmos app open and then click on the`Sign in` button.
|
||||
|
||||
That's it! You can now use Lunie with your Ledger Nano S. You will find your Cosmos address here:
|
||||
|
||||
|
||||
|
||||
**Note: Each time you will send a transaction, you will need to confirm it on your Ledger device. Indication will be prompted from the Lunie interface**
|
||||
|
||||
### (Optional) Confirm your address
|
||||
|
||||
You can double check that Lunie is displaying the correct address directly on your Ledger Nano device. To do so:
|
||||
|
||||
1. Connect your Ledger to your computer and open the Cosmos application on the device.
|
||||
2. Once the Cosmos app is open, click on the right button to access the `Show Address` option.
|
||||
3. Click on both button, then select `Account 0` and `Index 0`.
|
||||
|
||||
You should now see the same address that is displayed on the Lunie application.
|
||||

||||

## Gaia CLI + Ledger Nano

||||
|
||||
**Note: You need to [install the Cosmos app](#install-the-cosmos-ledger-application) on your Ledger Nano before using following this section**
|
||||
|
||||
The tool used to generate addresses and transactions on the Cosmos Hub network is `gaiacli`. Here is how to get started. If using a CLI tool is unfamiliar to you, scroll down and follow instructions for using the Lunie.io web wallet instead.

|
||||
|
||||
The Lunie web wallet supports signing with Ledger Nano S. Here is a short intro to using your Ledger with [Lunie.io](https://lunie.io).
|
||||
|
||||
### Connect your device
|
||||
|
||||
- Connect your Ledger device to your computer, unlock it with the PIN and open the Cosmos app.
|
||||
- Open [https://lunie.io](https://lunie.io) in your web browser (latest version of Google Chrome preferred)
|
||||
- Click “Sign in”.
|
||||
- Choose “Sign in with Ledger Nano S”
|
||||
|
||||
### Confirm your address
|
||||
|
||||
Run this command to display your address on the device. Use the `keyName` you gave your ledger key. The `-d` flag is supported in version `1.5.0` and higher.
|
||||
|
||||
```bash
|
||||
gaiacli keys show <keyName> -d
|
||||
```
|
||||
|
||||
Confirm that the address displayed on your Ledger matches that shown on Lunie.io before proceeding.
|
||||
Now you can use your Ledger key to sign transctions on Lunie.
