The Sandbox is a virtual world where players can create, own, and monetize their gaming experiences using blockchain technology. It allows users to build and design their own games and assets, which can be traded or sold in the form of non-fungible tokens (NFTs). In The Sandbox, players can explore various user-generated environments and interact with others in a decentralized ecosystem. The platform uses its native cryptocurrency, SAND, to facilitate transactions and reward creators, making it a unique blend of gaming and digital ownership.
