The quantum secure wallet launched on the Hong Kong HashKey Exchange in 2025 uses the "dynamic key sharding + biometric circuit breaker" mechanism to intercept phishing attacks more than 12,000 times per day, reducing the asset loss rate from the industry average of 0.8% to 0.03%. This breakthrough marks the shift of wallet security from "passive defense" to "active immunity", reconstructing the Web3 asset protection paradigm.
HashKey Exchange's quantum secure wallet adopts a 3/5 multi-signature mechanism: the private key is split into 5 shardings, 3 of which are stored in distributed HSM hardware modules, and 2 are generated by user biometrics. This design reduces the probability of single-point cracking to less than 10 ^ -30, while supporting the quantum signature algorithm XMSS to resist Shor algorithm attacks. According to Q2 2025 data, the wallet can process cross-chain transactions at a speed of 400 TPS, which is 3 times faster than traditional solutions.
Yuncong Technology's "Dynamic Live Detection" technology has been integrated into the wallet authentication system: through micro-expression analysis, vein recognition, and keyboard typing rhythm modeling, 10,000 + dimensional biometric feature vectors are constructed. After being adopted by a certain DeFi platform, the phishing attack recognition rate has increased to 99.98%, and the transaction confirmation time has been compressed from 30 seconds to 2 seconds. HashKey Exchange's biometric authentication system also controls the error rate to one in ten million, which is 10 times higher than traditional Face ID.
HashKey Exchange's "compliance adapter" combines on-chain and off-chain data: real-time scanning of transaction address labels and fund flows, intercepting operations associated with sanction lists. In Q3 2025, the system intercepted 12,000 suspicious transactions with a response time of less than 200 milliseconds, while retaining 80% of user privacy through zero-knowledge proof technology. After the adoption of a stablecoin project, compliance audit costs decreased by 70% and fund freezing efficiency increased by 5 times.
Faced with the Quantum Computing threat, the wallet has a built-in "AI circuit breaker engine": when Shor algorithm characteristic traffic is detected, it automatically triggers a three-level response - limiting transaction limits, freezing accounts, or transferring assets to cold wallets. After a cross-chain DEX integrated this technology, the asset loss in the Quantum Attack Simulation Test was reduced from 92% to 3%, and the high-frequency trading processing efficiency was increased by 50% by dynamically adjusting the hot wallet capacity.
The deployment cost of quantum security hardware is 300% higher than traditional solutions, while compatibility issues with biometric devices result in 15% of users being unable to use them. HashKey Exchange mitigates this contradiction through a "hybrid authentication" mode: biometric recognition is enabled by default, and backup solutions support hardware keys and multi-signature combinations, increasing the proportion of compliant users from 40% to 75%.
The European Union's Digital Asset Anti Money Laundering Regulation requires transactions to be traceable, forcing wallets to find a balance between privacy and compliance. HashKey Exchange's "zero-knowledge audit" technology completes compliance verification through zk-SNARKs without revealing transaction details. By 2025, cross-border transactions will be processed for more than 1 billion dollars, and privacy breaches will be reduced to zero.
