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.

Which PSPs and payment methods can you integrate?

We integrate global and regional PSPs, card networks, bank transfer rails, wallets, and QR-based payment methods, selected to match your target markets.

Can you build crypto payment options into our existing checkout?

Yes, we integrate crypto on/off-ramp providers alongside traditional rails behind a single checkout experience.

How does automated reconciliation work?

We ingest PSP settlement files and match them against your internal ledger automatically, surfacing only genuine exceptions for manual review.

Do you help reduce transaction decline rates?

Yes, through smart routing, retry logic, and PSP performance analytics that continuously optimize approval rates.

Payment Gateway & PSP Integration Services in South Korea

Every failed transaction is lost revenue and a trust hit. Hurain Technologies designs and builds payment integration layers — from single PSP connections to full payment orchestration hubs — for fintechs, digital platforms, and marketplaces that need reliable, reconcilable, multi-currency and multi-rail payment flows, including crypto on/off-ramps. In South Korea, that means building to the technical 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 payment gateway integration buyers 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

Problems we see teams struggling with

High transaction failure and decline rates

Poor PSP routing and retry logic silently loses revenue on every failed or declined transaction.

Manual reconciliation overhead

Finance teams spend days manually matching PSP settlement reports against internal ledgers.

Limited payment method coverage

Missing local payment methods and currencies caps conversion in new markets.

No unified view across multiple PSPs

Operating multiple PSPs without a central orchestration layer makes routing, reporting, and risk management inconsistent.

FX cost leakage on cross-border transactions

Without FX-aware routing, businesses absorb worse conversion rates and hidden markup on every cross-border transaction than necessary.

Checkout abandonment from unsupported local methods

Requiring a card when local users expect a wallet, bank transfer, or QR payment method caps conversion before checkout even begins.
