The Sandbox wallet

What is The Sandbox (SAND)?

SAND is the token that moves value around The Sandbox, a voxel world where creators build experiences and sell items as NFTs. It pays for marketplace purchases, in-world transactions and access to creator tools, and it is capped at 3,000,000,000 tokens with no minting beyond that.

For a holder, the thing to understand is that SAND is not one balance in one place. The token was issued on Ethereum as an ERC-20, and because Sandbox activity is expensive to run on mainnet, much of it happens with a bridged SAND balance on Polygon. The two are the same asset economically but separate token contracts on separate chains, and moving between them means using a bridge, not a normal transfer. Whichever chain the SAND sits on, the fee is paid in that chain's gas coin: ETH on Ethereum and on Base, POL on Polygon. SAND itself never pays the fee, so a wallet holding only SAND cannot send it.

The other half of a Sandbox position is usually not SAND at all. LAND parcels and ASSETS are NFTs, held separately from the fungible token, and selling a parcel does not move your SAND.

Supported networks in Tangem (3): Base, Ethereum, Polygon POS. Tangem keeps each of those balances distinct and names the network on the confirmation screen before the card signs, which is worth a glance when your SAND is split between mainnet and Polygon and you are sending to an address that looks identical on both. Holding a token that lives in two places at once is easier when the wallet never merges them into one number.
