#### 2. Install the Required Blockchain App
After downloading and opening Ledger Wallet / Ledger Live, you need to use the My Ledger feature to install the corresponding blockchain app on your Ledger hardware wallet.
The purpose of installing a blockchain app is to allow the Ledger device to support address generation and transaction signing for the corresponding network.
***
**2.1. Connect and Unlock the Ledger Device**
First, connect the Ledger hardware wallet to your computer or mobile phone.
Common connection methods include:
* Connecting to a computer via USB cable
* Connecting to a mobile phone via Bluetooth, applicable to Ledger devices that support Bluetooth, such as Ledger Nano X
After connecting, enter the PIN code on the Ledger device to unlock it.
***
**2.2. Go to the My Ledger Page**
After opening Ledger Wallet / Ledger Live, find and click:
```
My Ledger
```
After entering My Ledger, Ledger Wallet / Ledger Live will ask you to select your hardware wallet and confirm authorization on the hardware wallet device.
***
**2.3. Confirm the Connection on the Ledger Device**
The Ledger device screen may display a prompt similar to:
```
Allow Ledger Manager?
```
At this point, you need to press the buttons on the Ledger hardware wallet to confirm.
After confirmation, Ledger Wallet / Ledger Live can read the device information and display the list of blockchain apps available for installation.
***

After entering My Ledger, enter the name of the blockchain you need to install in the App catalog or search box.
For example:
```
Ethereum
Bitcoin
Tron
Solana
XRP
Cosmos
Cardano
```
After finding the corresponding app, click:
```
Install
```
During installation, please keep the Ledger device connected properly. Do not unplug the cable or close Ledger Wallet / Ledger Live.

**2.5. Common Networks and Their Corresponding Ledger Apps**
Different networks may require different Ledger apps. Common examples are as follows:
| Network / Asset | App Usually Required on Ledger Device |
| ------------------------------------------------ | ------------------------------------- |
| Bitcoin / BTC | Bitcoin App |
| Ethereum / ETH | Ethereum App |
| ERC-20 tokens, such as USDT-ERC20 and USDC-ERC20 | Ethereum App |
| Polygon | Ethereum App |
| BNB Smart Chain / BSC | Ethereum App |
| Arbitrum | Ethereum App |
| Optimism | Ethereum App |
| Base | Ethereum App |
| Avalanche C-Chain | Ethereum App |
| TRON / TRX / USDT-TRC20 | Tron App |
| Solana / SOL | Solana App |
| XRP | XRP App |
| Cosmos / ATOM | Cosmos App |
| Cardano / ADA | Cardano App |
A simple way to understand it:
```
EVM-compatible networks usually require the Ethereum App.
Non-EVM networks usually require their corresponding blockchain app.
```
For example, Polygon, BSC, Arbitrum, Optimism, and Base are different networks, but they are all common EVM-compatible networks. Therefore, they usually use the Ethereum App for signing.
***
**2.6. How to Confirm After Installation**
After installation is complete, you can check the installed apps in the Installed apps section on the My Ledger page.
If the corresponding app appears in the installed list, it means the installation was successful.
For example:
```
Installed apps:
- Ethereum
- Bitcoin
- Tron
```
