The Arc8 Wallet is what is known as a custodial wallet. That means that somebody else is in charge of keeping your cryptocurrency tokens safe (in this case, us!) and they can set their own rules about which tokens they accept. To use an analogy, if your personal wallet is a safe you keep in a cupboard at home (and put whatever you want in it!) then a custodial wallet is like a safe kept in the bank. Your tokens are safe in a custodial wallet, but you only have permission to send or receive tokens, nothing else. Also, some providers (such as Kucoin, for instance) might decide not to whitelist certain tokens, meaning if you send the wrong tokens there, they may be gone forever!
The Arc8 wallet accepts many kinds of Polygon tokens and NFTs, including of course GMEE, G-Bots and our various partner tokens. However, never send anything there except GMEE or it may disappear. Also note that you personally may never use this wallet – some people like to buy GMEE using the Arc8 wallet, while others prefer to use their own wallet. It's your call! There are instructions for both these options in this guide, though the Beginners Guide assumes you want to create your own wallet.
