Interactive Demo
Type any Nigerian location — a neighbourhood, street, LGA, or landmark — and see how AIG-CTG / G-DAPS produces a deterministic, machine-readable address code in the format: NG-STATE-LGA-00426. No database lookup required.
Try a sample location:
NG — __ — ___ — _____
Enter a Nigerian location above to generate its AIG-CTG / G-DAPS address code.
AIG-CTG / G-DAPS — Address & Identity Granularity / Grassroots Digital Address & Identity Network Address Patented Solution
“A deterministic address for every Nigerian, built from the ground up.”
AIG-CTG (Address & Identity Granularity) / G-DAPS (Grassroots Digital Address & Identity Network Address Patented Solution) is a Location-based National Digital Addressing System (N-DAS). Nigeria is divided into 102 billion 3m × 3m ultra-specific grid tiles, each assigned a unique, deterministic code encompassing the country, state, LGA, and a 5-digit unique identifier.
Unlike postcode systems that require a database lookup, AIG-CTG / G-DAPS codes are generated algorithmically. A code encodes its own location, you can decode an AIG-CTG / G-DAPS code without internet access, courtesy of the CRYLID offline solution.
The system is pyramidal: each Local Government Area forms a node in the hierarchy, enabling federated management while maintaining national uniqueness. The address format is: Country-State-LGA-UniqueID (e.g. NG-LA-IKJ-00426). Legacy analog addresses are migrated via reverse geocoding.
CRYLID · CRYLOID · CRYPLOID — Cryptographic Real-You Location/Possession Identifier
“Trust marks that make every address, person, and asset verifiable.”
Secured by CRYLID (Cryptographic Real-You Location/Possession Identifier) — the trust backbone of GRANDVIEW GRIDS (G2). It attaches a verifiable trust layer to any address-anchored entity — a person, a business, an asset, a transaction.
The Digital Trust Mark (DTM) is the client-facing credential: a mark issued to verified entities that can be queried by any authorised party in real time. DTM2 is the Digital Trust Map , the map-based trust overlay provides the scalable registry and API services layer.
Role separation is strict: Digital Trust Mark (DTM) & Digital Trust Map (DTM2) handle client presentation, CRYLID handles backend verification and cryptographic logic, CRYLOID & CRYPLOID provide backend verification and cryptographic login, CTM provides the services and API mesh. No duplication, clean interfaces.
NiNja Mapp + GRANDVIEW PROTIVA
“Geospatial cadastral intelligence for land, property, and infrastructure.”
NiNja Map (National Identity Number-linked Geospatial Address Mapping) is the geospatial cadastral navigation layer. Built with AIG-CTG address grids, land boundaries, and infrastructure overlays, providing the spatial context that makes addresses actionable. No external base map dependency.
A telco / MNO-assisted ground truth cadastre programme is planned to accelerate coverage and accuracy: partnering with Telco / MNO network data to verify and densify the address-to-boundary mapping at scale.
GRANDVIEW PROTIVA (Property-tied Verification & Authentication) extends this to property title verification. A marketplace where buyers, sellers, registries, and financial institutions can verify land and property title using the Cryptographic Real-Property Identifier, including a dedicated diaspora module for remote property investment.
Integration
GRANDVIEW GRIDS (G2) is API-first and designed to integrate with legacy systems through a reverse geocoding migration path.
Standard JSON/REST API for address lookup, code generation, and trust mark verification. OpenAPI documented.
GET /v1/address/resolveConvert any legacy Nigerian address string into an AIG-CTG / G-DAPS code. Handles variant spellings and LGA name changes.
POST /v1/address/migrateReal-time events for trust mark changes, verification status updates, and address registry changes.
