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 version lower than 100.0.5, you're required to update the app in order to continue using and connecting to SubWallet.
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:
Polkadot account
Manage, receive & transfer assets on fully Substrate-based networks (i.e., networks that use Substrate address format - starting with 5)
Ethereum account
Manage, receive & transfer assets on Substrate-based networks that are EVM-compatible (i.e., networks that use EVM address format - starting with 0x)
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 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".
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.
Step 3: In the account selection tab, click the button at the bottom right corner of the screen.
