Connect via the Polkadot app

This document will show you how to connect accounts on your Ledger device via the Polkadot app on SubWallet.

Understand the new Polkadot app

On July 1, 2024, the new Polkadot app was released (version 100.0.5). With this new app, you will be able to use a single Ledger account across any Substrate-based network.

To ensure compatibility with the new Polkadot app, all Substrate-based networks need to update their runtime logic. To check if a network has performed this action, visit the Parachains Metadata dashboard. If it hasn't, continue using the corresponding Ledger app.

If your Polkadot app is on a lower version than 100.0.5, you're required to update the app in order to continue using and connecting to SubWallet.

Connect your accounts via Polkadot app

Step 1: Have your Ledger device ready & connected to your computer. Choose the Polkadot App on your Ledger.

Step 2: Open the SubWallet extension and click on the account name to access the account selection tab.

Step 3: In the account selection tab, click the button at the bottom right corner of the screen.

Step 4: Choose "Connect a Ledger device".

Step 5: You will be directed to a new window. Select the Polkadot app, and your extension will display the following pop-up:

Click on the device name (Nano X in this case) and click "Connect".

Step 6: After SubWallet has successfully found your Ledger, click "Connect Ledger device".

Don't forget to turn on the corresponding app on the Ledger device.

Step 7: Choose the account(s) you want to use, then click "Connect Ledger device".

Step 8: Your Ledger account is ready!

If you repeat the action in Step 2, you will see your newly connected Ledger Polkadot accounts displayed in the "Ledger Account" section.
