0x364CaA63E832158520F90C267E7f9DBeAC0Ed515View on Etherscan →Mapstone Labs is a U.S.-based Web3 infrastructure company headquartered in New York City that anchors real-world addresses and postal codes as NFTs on Ethereum. By transforming physical locations into verifiable blockchain assets, Mapstone is building a standardized layer for geo-based digital assets.
Each Address NFT represents a single, unique real-world location secured by Ethereum smart contracts and enriched with structured mapping data. Users can mint, own, and trade these NFTs while participating in a broader ecosystem that connects geographic identity, blockchain infrastructure, and programmable location-based utility.
Beyond digital ownership, Mapstone introduces Address Quest™, a location-based rewards system tied to performance-based incentives. Through Address Quest™, users compete to earn ETH rewards through a transparent, rules-based system tied to real-world property data.
Data-driven insights generated across the platform may also inform broader initiatives, including investment strategies pursued by Mapstone Asset Management (“Mapstone AM”).
Originally launched as Ethereum Address Service (EAS), Mapstone has evolved into a geo-identity protocol designed to connect physical places with decentralized networks — enabling marketplace royalties, community incentives, and long-term participation tied directly to real-world geography.

0x1937265df8Ffcb1A50e1fE80fb366Bbd4076BE72View on Etherscan →Mapstone operates as a self-reinforcing cycle: community NFT activity across the platform reveals where interest and demand are growing geographically. Mapstone AM uses these insights to acquire and manage real-world assets in the markets with the most engagement, and places those properties into tokenized portfolios. Regulated real estate investment opportunities are then offered back to participants, allowing them to benefit from the value they helped create.
As participation grows, the system compounds by turning digital engagement into stronger market insight, deeper ecosystem activity, and broader long-term opportunities for the community.

Neighborhood NFTs represent unique U.S. postal codes on the Ethereum blockchain. Own a Neighborhood NFT and earn a 10% royalty from every qualifying Address NFT minted within its postal code, plus 1% from every Mapstone Marketplace sale.
Royalties are automatically paid in ETH to the owner’s wallet, giving Neighborhood NFT holders ongoing participation in activity across their market.
