Cross chain DEX How-to

How to Use the LiFi Cross-Chain DEX Widget on TheStandard.io

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.

Step 1: Access the Exchange Interface

Navigate to https://app.thestandard.io/dex. You'll see an interface similar to Image 1, with options to select the tokens you want to exchange.

Step 2: Select the Source Token (From)

• 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.

Step 3: Select the Destination Token (To)

• 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.

Step 4: Enter the Amount to Exchange

• 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.

Step 5: Review Exchange Details

• 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).

Step 6: Initiate the Exchange

• 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.

Step 7: Confirm the Transaction

• In your wallet (e.g., MetaMask), review the transaction details.

• Confirm the transaction and pay the associated gas fees.

Step 8: Wait for Completion

• 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.

Important Notes:

• 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.
