Geo-Based Digital Ownership Infrastructure

Mapstone is the first digital asset protocol to anchor real-world addresses on the blockchain — providing users with a structured pathway to property ownership.

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 ownership.

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 that connects NFT participation with structured real-world incentives. Through Address Quest™, participants compete on the Address Quest™ leaderboard and unlock access to tangible rewards — including real-world property opportunities — bridging blockchain engagement with physical asset value.

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 digital ownership tied directly to real-world geography.

How We’re Different

Neighborhood NFT Owners Generate Ongoing Earnings

Neighborhood NFTs on Mapstone represent the aggregate grouping of all individual Address NFTs from a unique postal code. As a Neighborhood NFT owner, you earn a share from every NFT minted within your neighborhood’s designated postal code, and you also earn a percentage every time these NFTs are later sold on the Mapstone marketplace. Earnings are automatically sent to the Web3 wallet address associated with your account.
