Mapstone

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 that connects NFT participation with structured, performance-based incentives. Through Address Quest™, participants compete on the Address Quest™ leaderboard and earn ETH rewards through a transparent, rules-based system tied to real world 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 to real-world geography.
