MetaMask Wallet
Visit OpenOcean trading interface, and select the chain you would like to swap, then click MetaMask. OpenOcean supports automatic configuration of networks. If it's your first time connect this chain, you only need to click Approve on the pop-up wallet window. Then you don't need to add the network again next time.
Select "Approve" to automatically add the network
After Approve, you will see your wallet address has connected to the chain on OpenOcean. Now you can start to swap!
In most cases, you can add the networks on wallets automatically. But somtimes, the automatically configured RPC nodes may be abnormal. Then you can choose manually add networks MetaMask or modify RPC by your own. Please see the following way to restore the network connection of the MetaMask wallet.
- Expand view, click my account then Settings
- Click “Networks” on the right side then you can modify RPC or add a network
- After entering the info, then click "Save" in the wallet
