KuCoin Adds CCSS Level 3 Certification to Its Multi-Layered Security Framework, Strengthening Trust Infrastructure for Digital Assets

PROVIDENCIALES, Turks and Caicos Islands, Sept. 24, 2026 /PRNewswire/ -- KuCoin, a leading global crypto platform built on trust, today announced that its Wallet Management Services have upgraded from CCSS v8.1 Level 2 to CCSS v8.1 Level 3 – Full System Certification. Assessed under the same v8.1 framework as its previous certification, the upgrade demonstrates greater control maturity across key management, organizational safeguards, incident readiness and auditability.

Level 3 strengthens controls throughout the cryptographic key lifecycle, from generation and storage to access, backup and recovery. Compared with Level 2, it introduces greater separation of responsibilities, more rigorous access and personnel controls, regular testing of key-compromise response procedures, broader independent assurance and continual backup of operational logs. Together, these measures further reduce single points of failure and strengthen traceability and resilience.

Designed specifically for cryptocurrency systems, CCSS complements broader information security standards by adding specialized requirements for the management and protection of cryptographic keys and wallets. It adds a crypto-native layer to KuCoin's multi-layered assurance framework, which includes SOC 2 Type II, providing independent assurance over the operating effectiveness of relevant controls; ISO/IEC 27001:2022 for information security management; ISO/IEC 27701:2019 for privacy information management; ISO 22301:2019 for business continuity; and ISO/IEC 42001:2023 for responsible AI management and governance. Together, these certifications establish an integrated framework spanning information security, privacy, operational resilience, AI governance and crypto-native asset protection, reinforcing oversight and accountability across KuCoin's operations.

"Trust is not established through a single certification; it is a system that must be continually tested, validated and improved," said BC Wong, CEO of KuCoin. "Advancing from Level 2 to Level 3 applies more rigorous controls to the people, processes and technologies that safeguard digital assets—from how key-compromise response procedures are tested and critical actions are recorded and made traceable. This is how we put trust into practice for users and institutions that rely on KuCoin."

For retail users, the enhanced controls provide stronger protection against unauthorized access, key exposure and operational failures. For institutional clients, the certification provides independent evidence that can support security due diligence, counterparty assessment and internal governance requirements.

The achievement reinforces KuCoin's investment in security, transparency and operational resilience. By combining crypto-specific controls with internationally recognized standards, KuCoin continues to strengthen the trust infrastructure required for responsible digital asset adoption and put trust into practice.
