The sandbox is a virtual game world. Through the functional token sand based on Ethereum, players can create, have and benefit from different game experiences. Gamers can create digital assets (non homogenous tokens, also known as NFT) through the sandbox game maker, upload them to the store, and create a game experience through simple drag and drop. The sandbox has established partnerships with more than 50 partners, including Atari, crypto kitties, encrypted cat, Shaun the sheet and so on, to establish a creative game platform of “playing and earning” created and owned by players. The sandbox aims to attract more encrypted and non encrypted game lovers and bring the blockchain into the mainstream game world through the advantages of real ownership, digital scarcity, profitability and interoperability brought by blockchain technology.
