Overview

In this guide we’ll be doing four crosschain transactions:

Sending XDC from XDC Network to Wanchain
Sending XDC from Wanchain back to XDC Network
Sending USDT from Ethereum to XDC Network
Sending USDT from Wanchain to XDC Network

We will also cover how to acquire wanUSDT on WanSwap

Note: Make sure you have MetaMask installed and connected to Wanchain network, and also have the XDC Pay Chrome extension setup and funded with some XDC.
Note: Bridging USDC between chains follows the exact same process as USDT. Just choose USDC in place of USDT.

Bridging XDC from XDC Network to Wanchain

Head over to WanBridge Web, then click “Connect to Wallet”.

Click on XDCPay as seen below.

Select “XDC” from the drop-down menu, then select “From: XDC Network” and “To: Wanchain”. Enter your destination address in the Recipient field (Your Wanchain address) and the amount you wish to crosschain convert, then click “Next”.

Confirm your details, then click “Confirm”.

Confirm the XDC Pay extension pop-ups (Click Submit)

Your XDC crosschain transaction will now begin processing, wait for it to show “Success”.

Add XDC token details to your MetaMask wallet:

Token Contract Address: 0xc7dca84A81324075e90A39250B0e07b7Daf4F45d

Click Import Tokens, then you should see your XDC balance reflect.

Bridging USDT from Ethereum to XinFin Network

Make sure you have your MetaMask connected to Ethereum Mainnet, then connect to WanBridge.

How to acquire USDT on Wanchain network via WanSwap

Head over to WanSwap and connect your MetaMask address. Make sure you are connected to Wanchain network, and have your address funded with some WAN.

Confirm the amount you wish to swap, then click “Confirm Swap”.

Confirm the MetaMask pop-ups, there will be two if this is your first time swapping on WanSwap.

Once your swap has completed, you’ll see the notification on the top right-hand corner.
