Can your fraud detection system flag market manipulation, not just account fraud?

Yes, our AI fraud detection platform can be tuned for abnormal-trading and market-manipulation pattern detection alongside account-takeover and payment fraud, which Korean exchanges are expected to monitor continuously.

Can you build open banking APIs without a full core system rewrite?

Yes. We wrap your existing core in a modern API middleware layer, exposing compliant account and payment APIs without touching core transaction logic.

How do you handle AML/KYC compliance during integration?

We build identity verification, sanctions/PEP screening, and transaction monitoring workflows directly into the platform, with audit logging that traces every decision for regulator review.

Can you integrate with our existing card and payment rail providers?

Yes, we connect correspondent banking, card networks, and instant payment schemes into a single orchestration and reconciliation layer.

What does an open banking API project timeline look like?

A typical account information and payment initiation API program, including a developer portal and sandbox, ships in 8-14 weeks depending on the number of endpoints and your existing infrastructure.

Banking & Fintech Software Development in South Korea

Banks and fintechs are under pressure to open their platforms via APIs, modernize legacy cores, and meet open-banking and AML obligations without disrupting existing operations or customer trust. In South Korea, that means building to the expectations of Asia-Pacific: Virtual asset service providers in South Korea operate under the Virtual Asset User Protection Act, enforced jointly by the Financial Services Commission (FSC) and Financial Supervisory Service (FSS).

South Korea Regulatory Landscape

What banking & fintech businesses in South Korea need to know

Virtual asset service providers in South Korea operate under the Virtual Asset User Protection Act, enforced jointly by the Financial Services Commission (FSC) and Financial Supervisory Service (FSS).
Exchanges are expected to implement real-name-verified bank account linkage for user deposits and withdrawals, a structural requirement distinct from most other markets.
Cold-storage custody ratios and abnormal-transaction monitoring for market manipulation are core technical expectations under the Act.
We build to these real-name banking, custody, and surveillance requirements, alongside Korea-licensed legal counsel for FSC/FSS registration.

The Challenge

What banking & fintech operators struggle with

Core systems that block product velocity

Vendor-locked core banking platforms turn a simple product change into a multi-quarter release cycle, while fintech challengers ship weekly.

Open banking deadlines without a clean path

Regulatory mandates require standards-compliant account and payment APIs on a fixed timeline, with no room for a risky core rewrite.

Manual AML/KYC review queues

Identity verification and sanctions screening still route through manual case queues, slowing onboarding and creating audit exposure.

Fragmented cross-border rails

Correspondent banking, card networks, and instant payment schemes are stitched together ad hoc, causing reconciliation gaps and settlement delays.

Our Approach

How we support banking & fintech in South Korea

Open banking & partner API programs

We design and build account information and payment initiation APIs with OAuth2/OIDC consent flows and self-service developer portals that cut partner onboarding from weeks to days.

Core modernization without a big-bang rewrite

Strangler-fig migration wraps legacy cores in modern middleware, letting you ship new products without a risky, multi-year core replacement.

AML/KYC and transaction monitoring automation

Automated identity verification, sanctions/PEP screening, and ML-driven transaction monitoring replace manual review queues and shrink false positives.

Cross-border payment hub integration

A central orchestration layer connects card networks, correspondent banks, and instant payment rails behind one reconciled ledger.

Audit-ready security & compliance controls

Secure architecture review, immutable audit logging, and regulator-ready reporting are built into the platform ahead of your next licensing or partner audit.
