You must not lose these keys. 3) Do NOT send REN to your Darknode, you need to register it using the Command Center (CC). You are interacting with a smart contract, the easiest way to make this interaction with a smart contract is through MetaMask. 4) MetaMask is the only way to interact with the Command Center (CC).
