Singapore Fintech Compliance: Privacy Infrastructure for MAS-Regulated Institutions

Singapore has established one of the world's most comprehensive regulatory frameworks for technology risk management in financial services. The Monetary Authority of Singapore's Technology Risk Management (TRM) guidelines, Notice on Cyber Hygiene (MAS Notice 655), and Payment Services Act create a layered compliance environment that governs how financial institutions and fintechs manage technology risk, protect customer data, and secure cryptographic operations.

For fintech companies and financial institutions operating in Singapore, compliance with these frameworks is not optional. MAS TRM applies to all financial institutions regulated by MAS, with no size-based exemptions. Digital banks, payment service providers licensed under the PSA, and fintech startups face the same framework as major banks, though MAS applies proportionality in practice.

Silence Laboratories is headquartered in Singapore and builds its MPC infrastructure for deployment in MAS-regulated environments. This guide covers the key regulatory requirements and how privacy-preserving infrastructure aligns with them.

MAS TRM Guidelines: Key Requirements

The MAS TRM Guidelines, revised in January 2021, establish the principles and best practices for technology risk management. The word "cyber" appeared 74 times in the 2021 update, compared to 4 in the 2013 version, reflecting the sharpened focus on cybersecurity. The guidelines cover:

IT governance. Boards and senior management must approve technology risk management frameworks. Clear accountability for technology risk is required at the board level.

Access controls. Strong authentication, privileged access management, and regular access reviews are mandatory. For MPC key management, this translates to requiring that key shares are accessible only to authorized processes, with audit trails for every signing operation.

Systems development and acquisition. Secure development practices, vendor due diligence, and security testing before production deployment. Any MPC library deployed in a MAS-regulated environment must undergo security testing and vendor due diligence.

Operational resilience. Critical systems must maintain a recovery time objective (RTO) of no more than 4 hours. MPC key management infrastructure classified as critical must meet this standard.

Incident reporting. The Authority must be notified within one hour of discovering a relevant incident. A root cause analysis report is due within 14 days.

MAS Notice 655 (Cyber Hygiene)

MAS Notice 655 (FSM-N06), effective May 2024, sets legally binding cybersecurity requirements for all regulated financial institutions. Unlike the TRM Guidelines (which are advisory but enforced through supervisory action), Notice 655 carries statutory force under the Financial Services and Markets Act.

Key requirements relevant to MPC key management:

Secure administrative accounts. All administrative access to key management infrastructure must use MFA and privileged access management.

Security patching. Vulnerabilities in MPC libraries and underlying dependencies must be patched on a schedule aligned with MAS expectations. Silent Shard's open-source codebase enables institutions to independently track and apply patches without waiting for vendor release cycles.

Network perimeter controls. MPC communication between key share holders must run within properly segmented network environments. On-premises deployment ensures this segmentation is under the institution's direct control.

Payment Services Act: Digital Asset Key Management

The Payment Services Act (PSA) governs digital payment token (DPT) service providers in Singapore. Entities offering custody, exchange, or transfer of digital payment tokens must be licensed by MAS.

For DPT service providers, key management is a core compliance obligation. The private keys controlling customer digital assets must be protected against unauthorized access, loss, and compromise.

MPC-based key management directly addresses this requirement. Key shares distributed across the institution's infrastructure eliminate single-point-of-failure risk. On-premises deployment ensures key material remains within Singapore's jurisdiction.

How MPC Infrastructure Aligns with MAS Requirements

Silence Laboratories in Singapore

Silence Laboratories is a Singapore-registered company (UEN 201938700D) building MPC infrastructure for financial institutions and digital asset service providers. The company's proximity to MAS-regulated institutions and direct experience with Singapore's regulatory environment informs its product architecture.

BIS Project Mandala. Silence Laboratories participated in BIS Project Mandala, a cross-jurisdictional privacy-preserving compliance case study covering sanction screening and capital flow management. The project addressed regulatory requirements across multiple jurisdictions, including Singapore.

G20 TechSprint 2025. Silence Laboratories won the G20 TechSprint with Proxtera for a cross-border MSME credit inference engine, recognized in the Trust and Integrity in Scalable and Open Finance category.

Linux Foundation Decentralized Trust. Silence Laboratories is a member of the Linux Foundation Decentralized Trust.

8 independent audits. Trail of Bits, Cure53, HashCloak, and Secfault have conducted security assessments of the Silent Shard codebase.

Singapore's Broader Privacy Landscape

Personal Data Protection Act (PDPA). Singapore's primary data protection law governs the collection, use, disclosure, and care of personal data. Financial institutions using MPC for data collaboration must ensure that their privacy-preserving computation architecture complies with PDPA requirements for data processing and cross-border transfer.

MAS AI Risk Management Guidelines (November 2025). MAS released consultation guidelines for AI risk management, identifying data governance as a standalone risk domain. For institutions using ML models trained on financial data, privacy-preserving computation (through Silent Compute's CCVM) addresses the data provenance and quality requirements by ensuring training data never leaves its source.

Singapore's Digital Asset Regulation. Singapore continues to develop its regulatory framework for digital assets, with the PSA as the primary vehicle. The clarity of Singapore's regulatory environment makes it an attractive jurisdiction for digital asset infrastructure companies, which is one reason Silence Laboratories is headquartered there.

FAQ

Does MAS TRM apply to fintech startups? Yes. All financial institutions regulated by MAS must comply with MAS TRM guidelines, regardless of size. MAS applies proportionality, so the expectations scale with the institution's risk profile, but the framework applies in full.

How does MPC key management help with MAS compliance? MPC distributes the private key into shares so no complete key exists anywhere. This addresses MAS TRM requirements for key material protection, access control, and operational resilience. On-premises deployment ensures data residency within Singapore.

Is Silence Laboratories a Singapore company? Yes. Silence Laboratories is registered in Singapore (UEN 201938700D) and headquartered there. The company builds MPC infrastructure for deployment in MAS-regulated environments.

What is MAS Notice 655? MAS Notice 655 (FSM-N06) is a legally binding cybersecurity notice requiring all MAS-regulated financial institutions to implement specific cyber hygiene practices, including MFA on administrative accounts, security patching, network perimeter controls, and malware protection. It took effect in May 2024.

Does MPC satisfy PDPA data residency requirements? On-premises MPC deployment keeps all key material and computation within Singapore's jurisdiction, satisfying PDPA requirements for data that must not leave Singapore. Managed platforms with cloud infrastructure in other regions may not meet this requirement.
