Decentraland is a semi free-to-play virtual game world owned by its users, for PC & Mac browser (running Chrome or Firefox), using blockchain (Ethereum), NFT & cryptocurrency (MANA) technology. Decentraland is a place for people to socialise, participate in events and play games, as well as to create & sell game assets (NFT 3D items for use ingame), showcase the art they have for sale or show off their art collection (NFT image/movie/audio, etc.), gamble crypto or free ingame gold, building and playing games within the Decentraland world, and more.
If you want to fully enjoy the Decentraland experience, it is recommend that you get yourself a digital wallet. Digital wallets work as your personal account, keeping all your digital assets (such as names, collectibles, LANDs) and in-world progress safe. If you choose to experience Decentraland without a wallet, the information will be only be locally stored: you will be able to walk around, customize your avatar and chat with others in-world, but you won’t have the chance to receive daily rewards, participate in events or log in with a different device using the same Guest ID and avatar.
