This guide will walk you through the process of using the LiFi cross-chain DEX widget on app.thestandard.io/dex. We'll use the example of exchanging SUSHI on Ethereum for WETH on Arbitrum.
Navigate to . You'll see an interface similar to Image 1, with options to select the tokens you want to exchange.
Click on the "From" field .
You'll see a list of popular tokens and chains.
Scroll down or use the search bar to find the token you want to send.
Click on the token you want to send (In the image examples we are choosing SUSHI on Ethereum to select it as your source token.
After selecting your token, the interface will update.
Click on the "To" field.
You'll see another list of tokens and chains.
Find and select The token that you want to arrive on the Arbitrum network.
We are going to WETH.
So in this example we are sending SUSHI on ETH and WETH will arrive on Arbitrum.
In the "Send" field, enter the amount of SUSHI you want to exchange (Image 5).
The interface will automatically calculate the amount of WETH you'll receive.
The widget will display the best return for your exchange.
You'll see the exchange rate, estimated gas fees, and transaction time.
If you don't have enough funds, a warning will appear (as shown in Image 5).
If you're satisfied with the exchange details and have sufficient funds, click the "Review bridge" button.
You'll be prompted to confirm the transaction in your connected wallet.
In your wallet (e.g., MetaMask), review the transaction details.
Confirm the transaction and pay the associated gas fees.
The widget will show the progress of your transaction.
Cross-chain transactions may take several minutes to complete.
Once finished, you'll receive your WETH on the Arbitrum network.
Always double-check the token symbols and networks before confirming a transaction.
Cross-chain transactions may incur higher fees due to the complexity of bridging assets between networks.
Market conditions can change rapidly, so the final amount received may differ slightly from the initial estimate.
Ensure you have enough ETH in your wallet to cover gas fees on both networks.
