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.

Select the right account type for use when connecting via Polkadot app

Starting from version 100.0.14, users will be able to connect and perform transactions on Substrate-based networks that use EVM addresses (e.g., Mythos, Moonbeam, Moonriver) through the Polkadot app. As these networks use a different signing method from those who fully Substrate-based, you will need to select a different account type to connect.

In particular, after selecting the Polkadot app option, depending on your needs, you will need to choose the account type you want:

Account type
Default account name
Compatibility

Polkadot account

Ledger Polkadot

Manage, receive & transfer assets on fully Substrate-based networks (i.e., networks that use Substrate address format - starting with 5)

Ethereum account

Ledger Polkadot (EVM)

Manage, receive & transfer assets on Substrate-based networks that are EVM-compatible (i.e., networks that use EVM address format - starting with 0x)

Unlike Ledger Polkadot accounts, Ledger Polkadot (EVM) accounts only support some tokens & networks. Check out the supported tokens & networks list below to send the correct token to this account type:

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. As the default app to connect is Polkadot, your extension will display the following pop-up:

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

Step 6: After connected, click on the "Select account type" field to choose the account type you want to connect.

Choose the account type you want to connect. In this example, we will choose "Ethereum account", which will then later be called "Ledger Polkadot (EVM)".

Step 7: After SubWallet has successfully found your Ledger with the chosen account type, click "Connect Ledger device".

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

Step 8: Choose the account(s) you want to use, then click "Connect Ledger device".

Step 9: 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.
