Transfer tokens via bridges
Hassle-free transfer tokens using bridges integrated into SubWallet.
Supported bridges
1. Supported tokens & channels
Currently, SubWallet supports these bridges to help you transfer tokens in-app directly:
Polkadot <> Kusama Bridge
DOT (Polkadot Asset Hub <> Kusama Asset Hub)
KSM (Polkadot Asset Hub <> Kusama Asset Hub)
Snowbridge
WBTC (Polkadot Asset Hub <> Ethereum)
WETH (Polkadot Asset Hub <> Ethereum)
MYTH (Polkadot Asset Hub <> Ethereum)
Avail Bridge*
AVAIL (Avail <> Ethereum)
AVAIL Turing (Avail Turing Testnet <> Ethereum Sepolia)
Unified Bridge**
ETH (Ethereum <> Polygon zkEVM
Polygon PoS Bridge
ETH (Ethereum -> Polygon)
WETH (Polygon -> Ethereum)
More bridges & channels will be supported soon!
(*): Once you initiate the transaction, you need to wait for the funds to reach the destination network. After that, you must manually claim the funds to complete the transaction.
(**): Once you initiate the transaction from Ethereum to Polygon zkEVM, you need to wait for the funds to arrive at Polygon zkEVM to complete the transaction. In the opposite channel, besides waiting, you need to claim the funds manually on Ethereum to complete the transaction.
2. Bridging time
WBTC (Polkadot Asset Hub <> Ethereum)*
WETH (Polkadot Asset Hub <> Ethereum)*
MYTH (Polkadot Asset Hub <> Ethereum)*
20 - 60 minutes
2 hours
AVAIL (Avail → Ethereum)**
30 - 40 minutes
90 minutes
AVAIL (Ethereum → Avail)**
75 minutes
90 minutes
ETH (Ethereum → Polygon zkEVM)*
30 minutes
40 minutes
ETH (Polygon zkEVM → Ethereum)
2 hours 30 minutes
3 hours
ETH (Ethereum -> Polygon)*
WETH (Polygon -> Ethereum)*
22 minutes

Transfer your tokens via Snowbridge
Step 1: Open the SubWallet app and tap the "Send" button on the homepage.
You will be directed to the Transfer screen.
If you are in Single-account mode, make sure the account you initially chose is not watch-only.
Step 2: Enter the required information in the corresponding fields.
In this example, we will transfer MYTH tokens on the Polkadot Asset Hub network to the Ethereum network from "Andy 2" to "Andy 1".
First, select the token you want to transfer by clicking on the top-left field (in this example, MYTH on Polkadot Asset Hub).
Next, select the destination network (the network you want to transfer tokens to) by clicking on the top-right field.
Enter the recipient's address, then hit "Next".
With this type of transfer, you can select the same account for both the sender and recipient.
Note that transferring tokens cross-chain to a centralized exchange (CEX) address will result in loss of funds. This is because these CEXs may not recognize or properly credit deposits made to their wallet addresses.
If you face this situation, it is recommended that you contact their support team as soon as possible.
Step 3: Enter the amount you want to transfer and then hit "Transfer".
Step 4: Read the popup message carefully, then click "Continue" to proceed.
The cross-chain transaction on Snowbridge usually incurs a high fee and can take 20 minutes to more than 2 hours to complete, depending on the bridge's status. Transfer at your own risk!
Step 5: Check your transaction details, then hit "Approve" to proceed.
Step 6: Transaction result is in!
You can select "Back to home" to return to the homepage or "View transaction" to see transaction details in the History tab.
If you press "View transaction", SubWallet will show you the latest transaction record in your transaction history along with the extrinsic hash of the transfer.
Transfer your tokens via Avail Bridge & Unified Bridge
With these bridges, except for the ETH transfer from Ethereum to Polygon zkEVM, you must claim the funds on the destination network to complete the transaction.
Transfer tokens to the destination network
Step 1: Open the SubWallet app and tap the "Send" button on the homepage.
You will be directed to the Transfer screen.
If you are in Single-account mode, make sure the account you initially chose is not watch-only.
Step 2: Enter the required information in the corresponding fields.
In this example, we will transfer AVAIL Turing tokens on the Avail Turing testnet network to the Ethereum Sepolia network within account "Andy 1".
First, select the token you want to transfer by clicking on the top-left field.
Next, select the destination network (the network you want to transfer tokens to) by pressing the top-right field.
Enter the recipient's address, then hit "Next".
Step 3: Enter the amount you want to transfer and then hit "Transfer".
Step 4: Read the popup message carefully, then click "Continue" to proceed.
Depending on the bridge's status, the cross-chain transaction on Avail Bridge can take 30 to 75 minutes for the tokens to arrive at the destination network. Transfer at your own risk!
Step 5: Check your transaction details, then hit "Approve" to proceed.
Step 6: Transaction result is in!
You can select "Back to home" to return to the homepage or "View transaction" to see transaction details in the History tab.
If you press "View transaction", SubWallet will show you the latest transaction record in your transaction history along with the extrinsic hash of the transfer.
Claim tokens on the destination network
If you transfer ETH from Ethereum to Polygon zkEVM, you won't need to follow the steps below, as the tokens will be credited to the destination network after the bridging time ends.
In the Notifications screen, look for the notification related to claiming bridged tokens, then click on that notification.
Step 8: You will be directed to the Claim tokens screen. Press "Continue" to proceed.
Step 9: Check your transaction details, then hit "Approve" to proceed.
Step 10: Your transaction has been submitted!
You can either click "Back to home" to return to the homepage or "View transaction" to see transaction details in the History tab.
If you click "View transaction", SubWallet will show you the latest transaction record in your transaction history along with the extrinsic hash of the transfer.
