How to switch chains
The default network setting in MetaMask is Ethereum Mainnet, which means sometimes you will need to set up MetaMask on other networks.
When you click the Connect Wallet button, if the network in MetaMask is different from current network (for example, BSC) in 0xGen, then you will be prompted to switch your wallet to the destination network.
Click Switch network button and the network will automatically switch to destination network.
The default network on 0xGen widget is customized by our partners, to switch to another network, all you need to do is a simple click on the button at the top left and a drop-down list of the supported networks will appear.
Once you choose another supported chain, then you will be prompted to switch your wallet to the destination network.
