The Sandbox is a decentralized virtual gaming world built on the Ethereum blockchain, allowing users to create, own, and monetize gaming experiences using non-fungible tokens (NFTs). Originally launched as a mobile game in 2011 by Arthur Madrid and Sébastien Borget, The Sandbox transitioned to a blockchain-based metaverse, offering a user-driven environment where creators maintain full ownership of their digital assets. Its native token, SAND, is used for transactions, governance, and staking within the ecosystem.
