## Swap tokens

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

**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.

{% hint style="warning" %}
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%.
  {% endhint %}

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

{% hint style="warning" %}
Swapping via SimpleSwap can take 5 to 60 minutes, depending on the market conditions.
{% endhint %}

**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.

{% hint style="info" %}
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.
