What is WanBridge?

WanBridge is the browser based interface for Wanchain cross-chain transactions between Wanchain and Ethereum. With WanBridge, you no longer need to download and install the WanChain desktop light wallet. Simply go to the WanBridge website and make sure you have the WanMask and MetaMask browser extension wallets installed. WanBridge currently officially supports only Google Chrome, but other browser which run Chrome extensions may also work.

2. Select Asset

On the next page, find the type of asset you want to convert, and click the “Convert” button on the right to start the cross-chain operation.

Use the filter box in the upper right corner to filter asset types.

Let’s take “ Wanchain <-> Ethereum” as an example.

The Storeman Group can be selected according to the quota (remaining amount of cross-chain asset allowance).
Choose your sending address and receiving address.
Enter the amount you want to convert, and then click “Confirm”.

Check your cross-chain transaction information again, click the “Start” or “Approve” button after confirming that it is correct ;

(If this is the first transaction for this asset, you need to authorize first. After authorization is successful, click the “Start” button)

After the authorization is confirmed, the cross-chain transaction has been submitted to the chain. At this time, you only need to wait for a while, and the cross-chain assets will arrive in your account soon.
