KuCoin Wallet Services Reach CCSS Level 3, Top Security Tier
Providenciales – – September 24, 2026 -- KuCoin has upgraded its Wallet Management Services from CCSS v8.1 Level 2 to CCSS v8.1 Level 3, the highest tier of the Cryptocurrency Security Standard, the exchange announced.
KuCoin secures full-system certification under the CCSS v8.1 framework
The Level 3 rating, assessed under the same v8.1 standard as the prior certification, verifies stronger controls across the full cryptographic key lifecycle, from generation and storage to access, backup and recovery.
New controls target key-compromise response and personnel access
Compared with Level 2, the Level 3 certification requires greater separation of responsibilities, stricter access and personnel controls, regular testing of key-compromise response procedures, broader independent assurance, and continual backup of operational logs. KuCoin said the measures reduce single points of failure and improve traceability and resilience.
