Technical overview

How GRANDVIEW GRIDS
works.

Three sovereign layers : Address, Verify, Map. That together makes every Nigerian, every place, and every asset location intelligent and verifiably trusted. Protected by master patent NG/PT/NC/O/2026/21832.

Interactive Demo

Generate an AIG-CTG address code

Type any Nigerian location, a neighbourhood, street, LGA, or landmark — and see how AIG-CTG produces a deterministic, machine-readable address code.

Try a sample location:

NG.--.---.----.--

Enter a Nigerian location above to generate its AiG-CTG address code.

LAYER 01

Address

AIG-CTG — Codes, Tiles & Grids

A deterministic address for every Nigerian, built from the ground up.

AIG-CTG is a tessellation based national addressing system. Nigeria is divided into a hierarchy of grids and tiles, from the LGA level down to individual properties, each assigned a unique, deterministic code.

Unlike postcode systems that require a database lookup, AIG-CTG codes are generated algorithmically. A code encodes its own location, you can decode an AIG-CTG code without internet access.

The system is pyramidal : each Local Government Area forms a node in the hierarchy, enabling federated management while maintaining national uniqueness. Legacy analog addresses are migrated via reverse geocoding.

NIGERIA · LAGOS · LGA-TILE · UNIT

NG · LA · IKJ · 0042 · B7

Key capabilities

  • Deterministic: codes encode position without lookup
  • Hierarchical: Country → State → LGA → Tile → Unit
  • LGA-centric federation: local autonomy, national uniqueness
  • Reverse geocoding: legacy address migration path
  • Machine-readable: API-first, no proprietary client required
LAYER 02

Verify

CRYLID Core + DTM/DTM2 + CTM

Trust marks that make every address, person, and asset verifiable.

CRYLID is the trust backbone of GRANDVIEW GRIDS. It attaches a verifiable trust layer to any address anchored entity such as 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 map based trust overlay. CRYLID Trust Map (CTM) provides the scalable registry and API services layer.

Role separation is strict: DTM/DTM2 handle client presentation, CRYLID handles backend verification and cryptographic logic, CTM provides the services and API mesh. No duplication, clean interfaces.

LAYER 03

Map

NINjaMap + PROTIVA NINja

Geospatial cadastral intelligence for land, property, and infrastructure.

NINjaMap is the geospatial cadastral navigation layer. Built on an OSM base, it layers AIG-CTG address grids, land boundaries, and infrastructure overlays. Providing the spatial context that makes addresses actionable.

A telco assisted ground truth cadastre programme is planned to accelerate coverage and accuracy: partnering with telco network data to verify and densify the address-to-boundary mapping at scale.

PROTIVA NINja extends this to property title verification. A marketplace where buyers, sellers, registries, and financial institutions can verify land and property title against the cadastral record, including a dedicated diaspora module for remote property investment.

Integration

Interoperable with existing systems.

GRANDVIEW GRIDS is API first and designed to integrate with legacy systems through a reverse geocoding migration path.

REST API

Standard JSON/REST API for address lookup, code generation, and trust mark verification. OpenAPI documented.

GET /v1/address/resolve

Reverse geocoding

Convert any legacy Nigerian address string into an AIG-CTG code. Handles variant spellings and LGA name changes.

POST /v1/address/migrate

Webhook events

Real-time events for trust mark changes, verification status updates, and address registry changes.
