# Connect via the Polkadot app ## 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](https://dashboards.data.paritytech.io/metadata.html). If it hasn't, continue using the corresponding Ledger app. {% hint style="warning" %} 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. {% endhint %} ## Select the right account type for use when connecting via Polkadot app Starting from version [100.0.14](https://github.com/LedgerHQ/app-polkadot/releases/tag/v100.0.14), 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: | Network | Token | | ------------------------ | ------- | | Mythos | MYTH | | Moonbeam | GLMR | | Moonriver | MOVR | | Crab2 Parachain | CRAB | | | CKTON\* | | Pangolin | PRING | | | PKTON\* | | Darwinia 2 | RING | | | PINK\* | | | KTON\* | | LAOS Network | LAOS | | Atleta Olympic (Testnet) | ATLA | | Moonbase Alpha (Testnet) | DEV | | Muse Testnet (Testnet) | MUSE | *(\*): Non-native token* ## 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:** On the SubWallet homepage, click on the account name in the upper-right corner 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 connecting, click on the "**Select account type**" field to choose the account type you want to connect.

A popup screen will appear on the right side. 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**". {% hint style="info" %} Don't forget to turn on the corresponding app on the Ledger device. {% endhint %}

**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.
