Why Now

The CBN ban is lifted. The SEC has issued licences. The build starts now.

Nigeria's crypto market did not die during the CBN ban — it went underground and grew. Now that the ban is lifted and the SEC has issued formal Digital Asset Exchange (DAX) licences, every serious Nigerian crypto business needs to build proper technical infrastructure fast.

The compliance requirements are specific: wallet infrastructure with KYC/AML at the smart contract level, proof-of-reserves, transaction monitoring and suspicious activity reporting to the EFCC. Overseas firms do not understand these requirements. Most local developers have never built to them.

KorabTech builds crypto infrastructure that meets both the technical and regulatory bar — from day one.

Regulatory Architecture
Map SEC/CBN licence requirements, design the compliance architecture and document VASP registration requirements.
2–3 weeks
Phase 2
Infrastructure Design
Design wallet key management, custody architecture, matching engine and database schema with security review.
1–2 weeks
Phase 3
Core Build
Build exchange backend, wallet infrastructure, KYC/AML integration and smart contracts in parallel sprints.
6–14 weeks
Phase 4
Compliance Testing
Chainalysis integration testing, KYC flow UAT, regulatory reporting dry-run with simulated EFCC submissions.
2 weeks
Phase 5
Security Audit
Smart contract audit, penetration test of exchange API, key management review and custody security assessment.
2–3 weeks
Phase 6

FAQ

Common questions answered honestly.

Do you help with SEC Nigeria DAX licence applications?
We provide the technical documentation that SEC Nigeria requires — system architecture diagrams, security policies, custody procedures, AML programme documentation and proof-of-reserves methodology. The legal application itself requires a licensed solicitor, but we work alongside your legal team to ensure the technical documentation meets SEC requirements precisely.
How do you handle private key security?
We design custody systems with HSM (Hardware Security Module) for key storage, multi-signature schemes requiring M-of-N signers for large withdrawals, cold storage for the majority of funds, and automated hot wallet top-up systems. We follow the same architecture used by Coinbase and Binance custody products at enterprise scale.
Can you build on top of an existing exchange codebase?
Yes. Many clients come to us with a white-label exchange solution that needs customisation, compliance layering and Nigeria-specific integrations. We audit the existing codebase, identify gaps, and build what is missing rather than rebuilding from scratch.
What stablecoins do you support?
USDC (Circle), USDT (Tether), EURC, and custom stablecoins we build for clients. We can integrate any ERC-20 stablecoin and have built naira-pegged token infrastructure. For CBN reporting, all stablecoin flows are mapped to FX transaction codes in line with CBN FX regulations.
