When qualifying Address NFTs are minted in a postal code before its Neighborhood NFT has been minted, the 10% Neighborhood royalties from those mints are held by the Mapstone smart contract in that postal code’s Neighborhood Reserve.
When the Neighborhood NFT is first minted, the smart contract automatically pays the accumulated reserve in ETH to the wallet that mints it. Afterward, royalties from new qualifying Address NFT mints are paid to the wallet that owns the Neighborhood NFT at the time of each mint.
Neighborhood Reserve amounts depend on actual qualifying Address NFT mint activity and may be zero.
Neighborhood Reserve balances are recorded on-chain and publicly verifiable. Advanced users can check a postal code’s current reserve by calling the getReserves(country, postalCode) read function on the MapstoneCore smart contract. For a U.S. postal code, enter United States for the country and the five-digit postal code.
