Many of the websites or applications you connect your wallet to require you to be using a specific network.
Currently, most websites use the main Ethereum network and new connections to your wallet usually default to this network. If you'd like to switch networks or wallets, you can easily do this in two ways on either your Android or iOS device:
Switching networks or wallets when first connecting to a site:
After scanning the WalletConnect QR code or tapping Rainbow in the WalletConnect list, a connection prompt will appear in the Rainbow app.
Step 1: Tap on the Network section in the bottom right corner of the connection prompt to bring up a list of available Networks
Step 2: Select the Network you want to connect with
Step 3: Tap on the Wallet section in the bottom left corner of the connection prompt to bring up a list of available Wallets
Step 4: Select the Wallet you want to connect with
Switching networks or wallets after you're already connected:
If you've already connected to a website and you want to go back and change your connection or wallet after the fact, you can do this from the Connection Manager screen.
Step 1: On your wallet main screen, you’ll click the More icon and then connected apps.
Step 2: View all of your existing connections in one place where you then can tap on the connection and either switch wallets, switch networks, or disconnect

What does this mean for you? It means inexpensive and instant transactions. On a network like Polygon, you might only pay $0.0005 in comparison to a $5 transaction on Ethereum. is an example of a Layer 2 network, and it's the first one being added natively to Rainbow.
