Players can connect MetaMask and other Polygon-compatible wallets that are supported by WalletConnect. You can check here if you wallet is supported by WalletConnect. 

It must be noted that even if you do not have a wallet, you can still play the game. Simply create an account on our website and get a Passport wallet automatically, which is connected to the game by default. You can check the Passport wallet address on your account page. However, without a wallet, you would not be able to use certain web3 functions like purchasing in-game items such as Silver and resources, owning NFTs from the game or staking MEE tokesn for extra benefits.
