Yes. Neighborhood NFTs are ERC-721 tokens on Ethereum, so owners may list or transfer them through compatible third-party NFT marketplaces.
If a purchase transfers the Neighborhood NFT to your wallet on-chain, you become its current owner. Future qualifying earnings associated with that postal code will follow the NFT’s on-chain ownership. This includes the 10% royalty from qualifying Address NFT mints and the 1% royalty from qualifying Address NFT sales completed through the official Mapstone Marketplace.
The third-party purchase itself does not use Mapstone’s marketplace allocation system, and Address NFT sales completed on third-party marketplaces do not generate the 1% Neighborhood royalty. To view the NFT and track its earnings through Mapstone, connect the wallet that owns it to your Mapstone account.
