Institutional
Custody
Infrastructure
SFC-compliant digital asset infrastructure for licensed institutions — custody, tokenization, financial data interchange, and trading on one integrated platform.
Four integrated layers.
One unified platform.
From institutional custody and tokenization to real-time financial data interchange — every capability built for regulated Hong Kong entities.
Banking-grade digital asset custody with HSM and MPC key management, configurable policy engines, and tiered storage — hot, warm, and cold.
Issue, manage, and service tokenized equity, debt, funds, and real estate on any blockchain with full lifecycle management.
Institutional-grade digital asset trading infrastructure integrated with custody and settlement, designed for SFC-licensed platforms.
Real-time reconciliation and audit trail engine with multi-institution data sharing capabilities — CDI-ready architecture.
Consent-Based Financial
Data Interchange for SME Cash Flow
Hashcode Algorithm Limited has submitted a formal proposal to the Hong Kong Monetary Authority's Commercial Data Interchange (CDI) Proof-of-Concept for Cash Flow Data Sharing. As Prime Tenderer, Hashcode leads the full technical architecture — DID/VC identity layer, consent execution mechanisms, secure API infrastructure, and governance controls — drawing directly on production experience deploying Digital Travel Credentials at international airports under ICAO standards.
Production-deployed Decentralised Identity framework using W3C DID/VC standards — the same architecture powering Digital Travel Credentials at Hong Kong International Airport under ICAO compliance. Enables privacy-preserving identity verification and consent-based data sharing across financial institutions.
End-to-end customer consent journeys with iAM Smart and CorpID integration, standardised consent forms, T&Cs, and privacy notices aligned with HKMA requirements. Full lifecycle management including consent validity, revocation, and auditability.
Interoperable API infrastructure for cash flow data exchange across participating banks, integrated with HKICL and CDI/IADS systems. Data encryption, digital signatures, and complete audit trail — designed for cross-institution SLA compliance.
Multi-party governance rules for participating banks, onboarding templates, and compliance controls for consent validity, data access, and accountability. Aligned with ISO 27001 controls and HKMA supervisory expectations — built by practitioners with offensive security, ISMS audit, and regulatory advisory certifications.
Hardware-level Trusted Execution Environment (TEE) isolation and key sharding protocols for transaction security — supported by core contributors to the Tongsuo open-source cryptography project (1,400+ GitHub stars) and Ant Group cryptographic infrastructure alumni.
Built on production-grade cryptographic infrastructure
Every component — from TEE-isolated key operations to W3C-verifiable consent credentials — engineered for institutional-grade reliability, auditability, and regulatory alignment from the ground up.
Four domains.
One integrated capability set.
Built by practitioners from Alibaba/Ant Group, Binance, and international financial infrastructure projects. Every domain directly relevant to regulated financial data exchange.
Production deployment of W3C DID/VC-based identity systems — Digital Travel Credentials (DTC) operational at international airport facilities, enabling privacy-preserving verification and consent-based data sharing under ICAO standards.
TEE-based secure computation, key sharding protocols, post-quantum cryptography research, and SM2/SM3/SM4 Chinese commercial cryptography standards. Core contributors to Tongsuo open-source cryptography (1,400+ GitHub stars) and RustyVault secrets management engine.
Institutional-grade digital asset custody platform (assets exceeding USD 2 billion) compliant with SFC, HKMA, and AMLO regulatory frameworks, with direct integration to banking settlement channels including FPS and CHATS.
Proven capability designing multi-institution API architectures for secure, auditable data exchange across regulated financial entities — directly applicable to CDI cash flow data sharing and cross-bank interoperability.
Built on battle-tested infrastructure
Every layer selected for institutional-grade reliability, regulatory alignment, and cryptographic soundness.
Built by practitioners,
not consultants.
Our team combines deep cryptographic research, production-grade identity engineering, and large-scale regulated financial delivery — with direct, hands-on track record across Hong Kong's financial and digital infrastructure.
Core contributors to Tongsuo, the open-source cryptography library with 1,400+ GitHub stars, and alumni of Ant Group's cryptographic infrastructure. Expertise in TEE, HSM, MPC key sharding, post-quantum algorithms, zero-knowledge proofs, and TLS 1.3. Offensive security certifications across red team and adversarial engineering disciplines.
Production deployments of W3C DID/VC-based identity systems — including Digital Travel Credentials at international airports under ICAO standards. ISMS audit, regulatory compliance advisory, and consent framework design for regulated financial environments. Deep familiarity with HKMA, SFC, and PDPO requirements.
Track record across HKD 12.1B government bond issuance, institutional custody platforms, and large-scale fintech delivery across Hong Kong and Greater China. Experienced in Agile programme management, bank stakeholder coordination, and integration with HK settlement channels including FPS and CHATS.
Production deployments.
Proven track record.
Real engagements with licensed institutions and public-sector bodies — not case studies built for show.
W3C DID/VC-based digital identity system deployed in live airport operations, enabling privacy-preserving identity verification, consent-based data sharing, and secure cross-border data exchange under ICAO standards. Contact: Winsor Chiu, Manager Future Travel Experience.
Institutional-grade custody, tokenisation, and financial infrastructure platform with secure key management, banking integration (FPS, CHATS), and multi-institution architecture. Ongoing IT governance and trust operations technology. Contact: Eva Tin, Operations Head.
Proof-of-concept project with Logistics and Supply Chain MultiTech R&D Centre involving trade finance and supply chain data flows, focusing on data interoperability and cross-institution data sharing aligned with SME financing use cases.
Built for Hong Kong's
regulatory framework.
Purpose-built to meet the requirements of Hong Kong's SFC, HKMA, and AMLO regulatory frameworks. Every design decision traces back to a compliance requirement.
Full compliance with Hong Kong's Virtual Asset Service Provider regime — dealing, custody, advice, and exchange activities under SFC oversight.
Architecture designed for HKMA's Commercial Data Interchange framework — consent flows, data governance, and interoperable API design aligned with CDI specifications.
Ready for the HKMA's stablecoin licensing regime under Cap. 656 — supporting fiat-referenced stablecoin custody and settlement infrastructure.
Built-in AMLO compliance with transaction monitoring, travel rule support, and automated suspicious activity flagging for licensed entities.
Security architecture designed in alignment with ISO 27001 control requirements. Project Lead holds CISA certification and conducts ISO 27001-aligned security assessments.
Prepared for the HKMA's e-HKD rollout and wholesale CBDC infrastructure, with tokenized deposit support and programmable settlement capabilities.
