Ledger x Keplr Compatibility

‍

Keplr supports Cosmos app chains, all EVM compatible chains including Ethereum, Injective and Evmos, and Starknet. This article will guide you through connecting your Ledger device with Keplr for Cosmos, EVM, and Starknet in order.

Install the necessary apps on your device using Ledger Live

• Cosmos app for Cosmos-based app chains.
• Ethereum app for EVM-compatible chains.
• Starknet app for Starknet.

Connect Hardware wallet (Ledger) for Cosmos

1. After installing Keplr Wallet for desktop, click on [Connect Hardware Wallet] and click [Connect Ledger], and give a name to your wallet.

2. Connect your Ledger to your desktop device by cable (or Bluetooth, if you have the Nano X), select “Cosmos App (recommended)” in the Keplr’s connection page, and open the Cosmos app on your ledger device. When you see ‘Cosmos ready’ on the Ledger screen, click [Next].
3. You will see the Keplr pop-up to grant permission to connect the hardware. Click [Nano S or X] and click [Connect].

4. Select the chains that you want to use and press [Save].

Connect to EVM-Compatible Chains‍

1. Keplr will next prompt you to switch to the Ethereum app on your Ledger device. You can skip this step if you are not going to use Keplr for EVM-compatible chains. Select the EVM-compatible chains that you want to use with Keplr and press [Save].
   

2. Open the Ethereum app on your Ledger and confirm the connection.
   

3. Your Ledger is now connected to Keplr for the selected EVM-compatible chains.

Connect to Starknet

1. After completing the EVM setup, Keplr will guide you to open the Starknet app on your Ledger. You can skip this step if you are not going to use Keplr for Starknet. Select the chains you’d like to use with Keplr, and hit [Save].

2. Open the Starknet app on your Ledger and confirm the connection.

3. Your Ledger is now connected to Keplr for Starknet. Now, the ledger connection for all three ecosystems are completed, and your Ledger account is successfully connected with Keplr.

Skipping Chain Connections

• Skipping a chain will not affect your ability to connect to it later.

Connecting to Skipped Chains Later

1. Open Keplr Wallet and go to the Sidebar menu.
2. Select Manage Chain Visibility.
3. Choose the chains you want to enable and connect them with your Ledger device.
4. Follow the prompts to complete the connection for the selected chains.
