This document will show you how to connect accounts on your Ledger device via the Polkadot app on SubWallet. |
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.
{% hint style="warning" %} 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. {% endhint %}
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 left corner of the screen.

Step 6: After SubWallet has successfully found your Ledger, click "Connect Ledger device".
{% hint style="info" %} Don't forget to turn on the corresponding app on the Ledger device. {% endhint %}
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.
