All you need is your regular browser. 2key automatically creates a plasma address for you and stores your rewards and reputation for you. So you neer lose them and can check your activity whenever you log in to your 2key account.
The 2KEY reward due to you thanks to your activity is displayed on your dashboard.
To collect these rewards, you will need a crypto-wallet.
If you already have a crypto-wallet, you can connect it to the 2key network and use it (2key network supports Metamask and Ledger accounts).
If you don’t have one yet, we recommend you start with a 2key wallet, because that will be the easiest way for you to use the 2key network.
