# KuCoin (KCS) Quantum Readiness Report

> KuCoin has a QRI score of 1/100 and is assessed at Stage 1 (Quantum Risk Assessed) with low evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: KCS token across Ethereum ERC-20 and KCC native deployments, including KCC consensus dependency.

KuCoin Token (KCS) is a standard exchange/utility token deployed as ERC-20 on Ethereum and native on KuCoin Community Chain (KCC), an EVM-compatible Layer 1 blockchain using Proof of Staked Authority (PoSA) consensus with 29 validators. Both environments rely entirely on classical ECDSA cryptography with no post-quantum implementation, migration plan, or quantum-specific risk assessment for KCS/KCC. KuCoin has demonstrated quantum-risk awareness through educational blog posts and a PQC Gateway Proof of Concept (December 2025) for TLS-level exchange web protection using ML-KEM and Dilithium, but this does not protect on-chain KCS token ownership, KCC consensus validator signatures, or blockchain transaction authorization. All KCS value-at-risk remains in ECDSA-vulnerable addresses and accounts with no migration path, recovery mechanism, or deprecation policy. The project scores at Stage 1 (Quantum Risk Assessed) due to general quantum awareness but lacks any meaningful production protection or migration readiness for the evaluated token scope.
