A New Instrument
of Property Truth

dAPTRA creates a permanent digital twin of every property in the Americas. Each registration produces a minted Omnichain Fungible Token — ERC-3643 compliant, Chainlink oracle-connected — embedding geospatial coordinates, 3D structure geometry, timestamped aerial imagery, and a certified appraisal into a single sovereign instrument.

This is the first registry designed from the ground up to become the ISO standard for spatial property identity. Built in Wyoming, designed for a hemisphere. Property without provenance is just possession — dAPTRA changes that permanently.

Canton-level private data access control ensures sensitive details remain accessible only to authorized parties, while World ID KYC guarantees verified identity without any data custody.

How dAPTRA Works

01
Register
Submit property details, parcel boundary data, and aerial imagery through the dAPTRA portal. Identity verification is handled via World ID — zero data custody, complete privacy by design.
02
Appraise
A dAPTRA-certified appraiser conducts a verified, standards-compliant valuation. This appraisal is cryptographically signed and baked permanently into the digital instrument — tamper-evident and universally verifiable.
03
Mint
Your property receives a permanent Omnichain Fungible Token on LayerZero — ERC-3643 compliant, Chainlink oracle-connected, and spatially anchored with 3D geometry. A sovereign digital identity, forever on-chain.

On the Path to
ISO Recognition

dAPTRA is structured as a Wyoming LLC with a clear, deliberate trajectory toward nonprofit status and ISO standardization. Our work is designed not just as a product, but as a public instrument — a global commons for land truth that any nation, municipality, or institution can adopt. We are building the technical and governance foundations for spatial property identity to become universal, open, and cryptographically verifiable across the Americas and beyond.

Property without provenance is just possession.
