No. SAND is the name of a fungible Ethereum token. These tokens, called ERC-20s, are all interchangeable, just like how each Canadian dollar is exchangeable for another Canadian dollar. However, The Sandbox game uses NFTs, or non-fungible tokens—cryptocurrencies that are unique and not interchangeable—to represent property rights over in-game items. The first type of NFT is called LAND. This represents parcels of in-game land on which you can build virtual worlds. The second are in-game assets, like buildings, costumes or pieces of furniture, that you can use within The Sandbox.
