With this type of swap, you can choose to swap your tokens to another account.

Swap tokens

Step 1: On the SubWallet app, hit the "Swap" button on the homepage.

If this is the first time you use this feature, the Terms of service popup will appear. Read carefully, then select "I understand the associated risk and will act under caution". After that, click "Confirm and continue swapping".

Step 2: On the Swap screen, select the token you want to swap and the token you wish to receive.

In this example, we want to swap DOT (Polkadot) for ETH (Ethereum).

Select "DOT (Polkadot)" as the token you want to swap.

Select "ETH (Ethereum)" as the token you wish to receive.

If you're in the "All accounts" mode

In this case, you will need to select the swapping account.

Enter the amount you want to swap. Once done, the swap quote (with the related information) will appear. Hit "Swap" to proceed.

If you want to change the swap provider

ℹ️ This feature is available for swap pairs on the Ethereum network.

To do that, hit the "View swap quote" button, then continue clicking on the "View quote" button.

In the Swap quotes popup, choose the provider you want for the swap.

You cannot change the slippage tolerance with this swap type:

• With ChainFlip, every swap has a fixed slippage tolerance of 2%.

• With SimpleSwap, the slippage tolerance can't be predicted as it varies based on market conditions, but it will never exceed 5%.

Step 3: Check your transaction details, then click "Approve" to proceed.

Swapping via SimpleSwap can take 5 to 60 minutes, depending on the market conditions.

Step 4: Your swapping request 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.
