How to complete a crosschain transaction (USDT XFlows)
An in-depth guide outlining how to complete a native USDT crosschain transaction using the WanBridge web portal and MetaMask.
Wanchain bridges now support USDT XFlows. USDT XFlows are native-to-native USDT crosschain transfers between blockchains where USDT is natively minted by Tether, such as Ethereum, BNB Chain, OKC, Polygon and Arbitrum. This means that users can use Wanchain’s industry-best crosschain infrastructure to execute decentralised, non-custodial native-to-native USDT crosschain transfers while maintaining interoperability with pre-existing wrapped versions of USDT.
This guide will demonstrate three separate crosschain transactions:
- $USDT from Ethereum to Arbitrum using the WanBridge web portal with Metamask
- $USDT from Arbitrum to Polygon using the WanBridge web portal with Metamask
- $USDT from Polygon to OKC using the WanBridge web portal with Metamask
Note: All crosschain transactions between EVM networks follow the same process. This includes all supported EVM networks including Wanchain, Ethereum, Avalanche, BNB Chain, Fantom, Moonriver, Moonbeam, etc.
Crosschain transactions using the WanBridge web portal
$USDT crosschain transaction from Ethereum to Arbitrum
Step 1: Make sure you have the appropriate wallets installed.
Before completing decentralised crosschain transactions using the WanBridge web portal, you need to ensure you have access to the correct wallet(s). You must have wallets for each network involved in the crosschain transaction. Metamask is a fantastic wallet that grants you access to any EVM-compatible blockchain networks.
Step 2: Visit the WanBridge web portal and connect your wallet.
Click “Connect to Wallet”.
Click “Metamask”.
If this is your first time using the WanBridge web portal, you will first need to give permission to connect your wallet. Follow the MetaMask prompts by clicking “Next” then “Connect” as instructed.
Step 3: Initiate a crosschain transaction to move your $USDT from Ethereum to Arbitrum.
Select “USDT” from the drop-down menu. Then, choose “Ethereum” and “Arbitrum” as your From and To networks, respectively. Finally, input your destination address in the “Recipient” field as well as the amount of $USDT you want to send crosschain. Click “Next”.
Confirm that the “Recipient” address does not belong to a centralised exchange then click “Confirm”.
Confirm that all the details are correct then click “Confirm”.
Confirm the spend permission request by clicking “Confirm” in the MetaMask pop-up window.
Confirm the transaction by clicking “Confirm” in the MetaMask pop-up window.
Step 4: Wait for your crosschain transaction to complete. It is now processing.
While your crosschain transaction is processing, the status will change three times:
- Processing (1/2)
- Processing (2/2)
- Success
Note: The speed of the crosschain transaction is entirely dependent on the networks involved. Transactions involving slower networks like Bitcoin or Ethereum may take several minutes or more to complete.
Step 5: Confirm the receipt of your funds. Your crosschain transaction is complete!
Once your crosschain transaction is complete, you’ll see your $USDT balance on Arbitrum and the crosschain transaction status change to “Success”.
