Platform Architecture & Engine

The Core Middleware Processing Millions of Airtime & Fintech Transactions Daily

NexusCraft combines a high-throughput Unified Operator Gateway with an immutable, real-time Automated Reconciliation Engine.

Deep Dive 01

Unified Operator Gateway

One ingress contract in front of every carrier connection, engineered for transaction-grade volume and predictable failure behaviour.

Bi-Directional Payload Normalization

SOAP/XML, ISO 8583 and socket payloads translated to a single canonical JSON contract — and back — on every hop.

Intelligent Traffic Management

Per-operator health scoring, weighted routing and circuit breaking keep degraded rails out of the live path.

High-Throughput Kafka/Redis Ingestion

Partitioned event ingestion with Redis-backed hot state sustains 10,000+ transactions per second without backpressure.

Configurable Retry & DLQs

Idempotent retry policies per operator, with dead-letter queues and replay tooling for anything that falls out of band.

Deep Dive 02

Automated Ledger & Reconciliation Engine

Every transaction is committed as an atomic three-way match. If any leg fails to settle, the entry is isolated for dispute rather than silently absorbed.

Leg 1

Bank Debit

Institution account debited and pre-authorised.

Leg 2

Dealer Margin

Commission posted against the dealer's float position.

Leg 3

MNO Fulfillment Receipt

Operator confirmation closes the atomic transaction.

Dispute isolation

Unmatched legs are quarantined into a dispute ledger with full payload evidence, so a single operator timeout never contaminates settlement for the wider book.

Multi-level sub-dealer float

Hierarchical float pools with inherited credit limits, per-tier margin schedules and real-time depletion alerts across every level of the distribution tree.
