By default, MetaMask only supports the Ethereum network. However, you can configure MetaMask to work with the Oasis Emerald ParaTime, which is where Oaswap lives and operates. To configure MetaMask for Oasis Emerald, go to Settings > Networks > Add Network and then enter the following network details:
- Network Name: Oasis Emerald
- Chain ID: 42262
- Currency Symbol: ROSE
To perform transactions on Oaswap or any other Oasis Emerald applications, you may need ROSE for gas.
