Why Now

Nigeria's blockchain moment is already here.

The SEC has started issuing Web3 operating licences. NIBSS — Nigeria's national payment switching company — is already live on blockchain. The CBN lifted its blanket crypto banking ban. Nigerian financial institutions, exchanges and enterprises now have both the regulatory path and every business reason to build real blockchain infrastructure.

The bottleneck isn't demand — it's supply. Very few firms in Nigeria can deliver enterprise-grade Solidity development with a proper audit process behind it. Most companies still end up routing their contracts through London, Dubai or Singapore, paying a premium for engineers who've never actually worked inside the Nigerian regulatory environment.

KorabTech fills that gap. Certified engineers, Nigerian regulatory expertise, global execution standards.

Use Cases

Real Nigerian business problems we solve.

Live opportunities in the Nigerian market — businesses currently paying overseas rates for these exact solutions.

01
🏦 Fintech & Banking
On-chain Payment Settlement for Nigerian Banks
Replace NIBSS batch settlement with real-time on-chain clearing. Smart contracts handle interbank settlement directly, cutting reconciliation time from a full day down to near-instant, and create an immutable CBN audit trail.
02
🏛️ Government
Blockchain Land Registry for State Governments
Tokenise land titles on a permissioned chain — every transfer and ownership history is immutable and publicly verifiable. Eliminates double-sale fraud costing Nigerian buyers billions annually.
03
🚚 Supply Chain
Agri-commodity Traceability Farm to Export
Track Nigerian cocoa, sesame and cassava from smallholder farms to export containers using on-chain provenance. Meets EU Deforestation Regulation requirements Nigerian agro-exporters must comply with.
04
🏪 SMEs
Tokenised Invoice Financing for SMEs
SMEs tokenise outstanding invoices as NFTs and auction them to liquidity providers — getting immediate working capital without waiting on traditional bank credit. A real answer to Nigeria's persistent SME financing gap.
05
💱 Crypto
SEC-licensed Crypto Exchange Backend
Full smart contract backend for a CBN/SEC-compliant exchange — KYC/AML on-chain verification, custodial wallet contracts, proof-of-reserves and automated regulatory reporting.
06
🏥 Healthcare
Patient Health Records on Hyperledger
Permissioned blockchain for hospital networks — patients control access to records, every data access is logged immutably, and inter-hospital sharing happens without a central authority.

Our Process

How a Blockchain & Web3 project gets built.

Every project follows a structured, phased delivery process. Each phase has a defined deliverable, a sign-off milestone and a go/no-go before the next phase begins. You see exactly where your project stands at all times.

Phase 1
Discovery & Architecture
Requirements workshop, chain selection, security threat modelling and full technical architecture document.
1–2 weeks
Phase 2
Smart Contract Development
Solidity authoring with NatSpec documentation, unit and integration tests (100% coverage target), gas optimisation.
2–6 weeks
Phase 3
Internal Security Review
KorabTech internal audit — reentrancy, access control, overflow, front-running. Findings fixed before external audit.
1 week
Phase 4
Testnet Deployment & QA
Deploy to Sepolia/Mumbai testnet. Integration testing with frontend dApp, load scenarios, client UAT.
1–2 weeks
Phase 5
Mainnet Deployment
Production deployment with multi-sig controlled upgrade keys. Contract verified on Etherscan/Polygonscan.
3–5 days
Phase 6
Monitoring & Support
90-day post-launch support, on-chain monitoring via Tenderly alerts, incident response SLA.

FAQ

Common questions answered honestly.

Do you handle CBN and SEC compliance for blockchain projects in Nigeria?
Yes — every blockchain engagement includes a compliance review against CBN's VASP framework, SEC Nigeria's DAX guidelines, and NDPC data protection requirements. We build compliance into the architecture, not as an afterthought.
Which blockchain — Ethereum, Polygon or BNB Chain?
It depends on your use case and transaction volume. Ethereum mainnet offers the highest security for high-value contracts. Polygon is our default for consumer-facing apps and Nigerian SME use cases due to near-zero fees. BNB Chain suits high-frequency trading. We cover this in the architecture phase.
How long does a typical smart contract project take?
A single well-scoped contract typically takes 2–4 weeks from kick-off to mainnet. A full dApp runs 6–12 weeks. A full protocol is 3–6 months. Scope creep is the primary cause of delays — we mitigate this with a detailed architecture document before writing a single line of code.
Do you audit contracts you did not build?
Yes. We conduct independent audits for third-party contracts — built by your internal team, another agency or a freelancer. Our process covers manual review, automated analysis with Slither and Echidna, and a findings report with severity ratings. Contact us for audit-only engagement pricing.
