How to Swap

One of Bridges' core values is ease of access. We've redesigned the typical DEX interface to be more friendly and provide hints to make everything clear and transparent. Nevertheless, if it's your first time swapping, you might want a little more guidance.

Set up your wallet

Before you can swap, you will need a compatible non-custodial wallet. We recommend setting up a MetaMask wallet if this if you first time in DeFi. Read our guide or watch our video for step-by-step instructions.
In order to swap, you'll also need to have native coin for the gas fees, and either native coin or another token on that chain that you can use to swap.

Connect and swap

Start by going to the Swap page on Bridges Exchange. Connect your wallet in order to interact with the exchange. If you don't know how to connect your wallet yet, read our guide here.

Check token information

On the right, you'll see information about the tokens that you want to swap. You can use this as a guide to learn more about the tokens that you want to swap, and to ensure that these really are the two tokens that you mean to swap.
The percentage of liquidity locked by the developer, if any, is computed as: the amount of LP tokens locked by the developer divided by the total LP token supply. As other users start depositing and withdrawing liquidity—therefore increasing and decreasing the LP tokens supply—the value shown will change accordingly.

Understand the swap card

Now, let's take a look at the Swap card on the left. There are a few important features that you need to be aware of.
In the upper right, you'll see three icons. From left to right, these buttons are:
  • Transaction speed (GWEI): Leave this at the default level, as this is more of an advanced feature.
  • Recent transactions: For your convenience, you can find all of your recent transactions on Bridges Exchange here.
  • Refresh prices: You can manually update the price quote by clicking this button. It's not necessary to click it, as the prices are automatically updated as long as you stay on the page.
Next, you see the input token which is the token that you are providing for the swap. The input field below that is the output token, or the token that you will receive from the swap. If you want to switch these so that the opposite tokens are in the input and output position, click the arrow in the middle.
On the left of the input field, you can see real-time USD pricing of the tokens that you are swapping. On the right above the input field, you can see your current balances of each selected token.
Finally, below the two input fields, there is a slider for slippage tolerance. You can also manually type the exact slippage tolerance in the field on the right.

Choose your tokens and swap amount

You can click on the token name above the bar to select a different token from the list of Bridges Approved tokens. The list shows both the name, ticker, and logo of each token on the left, and your balance of those tokens on the right. If a token is already one of the two selected tokens, you cannot select it again.
Once you choose your two tokens and have them in the correct order, enter the amount you want to swap of one of the tokens. The other token amount will automatically populate depending on the current ratio between the two tokens in the liquidity pool (this sets the relative price).
Make sure that you have enough of the input token, or you will not be able to execute the swap. If you want to swap all of a token that you hold, then you can click on the Max button below the input token field.

Set your slippage tolerance

To begin, we recommend that you leave the slippage tolerance at the default value unless you know what you are doing.
If you're wondering what slippage is, it's the maximum difference in tokens between what you enter and what you actually receive that you're willing to accept. Other people are also swapping, and the price can change quickly, especially in times of high volatility.
If the price changes a lot, you could get a much worse price than you wanted. That's why we have slippage tolerance to limit how much of a difference you're willing to accept. If the amount you will receive is outside of your slippage tolerance, then the transaction will fail.
Given that each swap changes the ratio of the tokens in the liquidity pool, your swap will impact the price. The bigger the swap, the bigger the price impact. If you are swapping an amount that impacts the price too much, then you will not be able to complete your swap. Try swapping smaller amounts instead if you run into this issue.
If you have a higher price impact, you'll also need a higher slippage tolerance. You can think about this as the swap price of the first token being much different from the last token in your transaction. If others are swapping at the same time and causing price shifts, then your transaction can fail with too low slippage.

Enable the token

If it's your first time swapping a particular token, you'll need to enable it first. To do so, click Enable and follow the prompts from your wallet to approve the token.
All of the information related to your swap will be shown in the card below the swap card. The Dividends fee field will only be shown if the token is included in the 0.1% dividends fees. If you don't see this field, then the token you selected is excluded from the dividends fees.


When you're ready, check that everything looks correct, and click the Swap button.
A modal will appear asking you to confirm the details of your swap, and detailing the transaction information including fees.
If you're satisfied with the details of the transaction, click Confirm swap.
At this point, your wallet will prompt you to approve the swap. Follow the steps for your specific wallet to do so.
Once you have confirmed, you'll see that your transaction is processing. Wait just a moment, and you'll see whether your transaction was successful or it failed.
If everything goes well, you'll see a success message. You can click View to see your transaction details on the blockchain explorer.

The routing card

The routing card will show you how your trade will be routed, including the liquidity sources involved if there is more than one
Example selling 10 BNB for Filecoin

The comparison card

The comparison card will show you how the quote you are getting from the Bridges Exchange's aggregator compares to single decentralized trading protocols, if more than one protocol is involved.

If something goes wrong, you'll see an error message appear. Follow the instructions on the error message to resolve the issue, and try swapping again.
If your slippage tolerance is too low, then we recommend that you only increase this by 1%, and try again. If it fails a second time, try increasing by another 1%. We suggest that you only increase the slippage in intervals of 1% in order to not overpay for your tokens.
