You can send FTM Opera tokens to any Ethereum address on MetaMask, but first, you need to configure your MetaMask wallet to access the Fantom blockchain. Follow these steps to do that: Login to your MetaMask wallet. Select Networks then select Custom RPC. If you are on the mobile app, go to settings then networks and select "Add Network". Fill in the fields as follows: Network Name: Fantom Opera New RPC Url: https://rpcapi.fantom.network​ ChainID: 250 Symbol: FTM Block Explorer URL: https://ftmscan.com/ Click Save. Fantom should now be available in the networks. Transactions on the Fantom network require FTM which is the native token of Fantom, for a gas fee.
