Crypto Asset Service Providers: CASP Technical Compliance Architecture

The crypto economy continues to be one of the fastest-growing ecosystems in the financial world. Millions of users in Turkey are trading crypto assets, and this widespread usage brings the sector to a critical point: regulatory compliance. Because a large market can only thrive on a solid framework of trust.

As of 2024, Crypto Asset Service Providers (CASP) in Turkey have been brought under the scope of Law No. 5549 and have transitioned to financial institution status. With this new era, security, reporting, and regulation standards set by MASAK, SPK, and TÜBİTAK must now be applied at the banking level. CASPs are no longer just an "exchange"; they have become one of the most critical players in the national financial infrastructure.

Therefore, the answers to the following questions must now be very clear and documented:

• Do we really know the user?
• Are we proactively managing transaction risks?
• How resilient are our systems against cyber attacks?
• Are we fully compliant with tomorrow's regulatory audit?

This article explains the technical aspects of all these questions and outlines the compliance architecture necessary for KVHSs to move forward with confidence.

MASAK Compliance: Trust at the Heart of the System

From a traditional perspective, MASAK compliance is often seen as "document processes." However, in the world of crypto assets, the power of compliance comes from the technical infrastructure. In other words, true compliance begins not on paper but at the core of the system.

MASAK compliance is built on four core competencies:

KYC/eKYC: The Starting Point of Trust

The quality of identity verification is the first line of defense in risk management. Biometric facial recognition, liveness detection, ID card NFC verification, address/occupation confirmation, and real-time data checks against government systems not only verify identity but also reveal the customer's behavioral profile. The stronger the identity verification structure, the earlier manipulative AML attempts are detected.

Suspicious Transaction Reporting: The Critical Role of Speed

When a suspicious transaction is detected, a race against time begins. MASAK requires reporting within 10 business days at the latest in normal scenarios and immediately in critical situations. When this process is not supported by automated risk scoring, decision support systems, and regulator integration, manual delays become compliance risks.

Continuous Behavior and Transaction Monitoring: Adaptive AML

AML is no longer just about rule sets. Modern monitoring systems, supported by artificial intelligence capable of detecting out-of-profile behavior, risk matrices, and dynamic alert mechanisms, accelerate the detection of suspicious transactions. Today's regulations no longer penalize negligence, but rather delayed intervention.

Travel Rule: Global Transparency Standards

Crypto knows no borders, but regulation does. For transfers of 15,000 TL and above, the secure transfer of party data is mandatory. The backbone of international compliance is the IVMS101 message format and VASP-to-VASP instant communication structures. A failure here could lead to the closure of international exchanges, weakened banking relationships, and heavy sanctions.

SPK and TÜBİTAK Requirements: Resilience, Continuity, and Security

A crypto platform is only sustainable as long as it remains compliant. The second major pillar of compliance is information security and operational resilience.

The SPK's technical expectations target these three fundamental principles:

• Data security → protection of customer assets
• Infrastructure resilience → prevention of service interruptions
• Disaster recovery → rapid recovery in critical scenarios

TÜBİTAK audits cover a wide range of controls, from access authorization models to DDOS protection, log integrity to penetration testing. If a system becomes inoperable after a cyber attack, compliance has already been violated.

Managing Converged Architecture: Modern CASP Infrastructure

Bringing all requirements together in a converged manner is actually where innovation begins. Next-generation KVHS platforms focus on the following features:

• API-based integration architectures
• Real-time AML engines
• Auditable workflows
• High availability (HA) and automatic failover infrastructures
• Logging in accordance with SKDD/MEK standards
• ISO 27001 compliant security model

This architecture is not a "strong technology preference"; it is now a legal requirement.

Why Is All This Necessary?

Compliance is not a cost center; it is a competitive advantage. The right compliance strategy:

• Builds customer trust
• Opens doors to collaboration with global exchanges and banks
• Ensures credibility with investors
• Guarantees long-term sustainability

Crypto platforms investing in compliance today will be the only real players standing in tomorrow's market.

Are You Ready for a Regulated Future?

The new definition of competition in the crypto sector is trust. This trust is not earned through a marketing campaign or low commissions alone. The only factor that will determine the future of the sector is establishing a robust, auditable, and technology-focused compliance architecture.
