- OneKey confirms wallets remain secure despite Milk Sad vulnerability concerns.
- Hardware wallets use certified random generators ensuring uncompromised private key protection.
- Company advises users to rely on hardware wallets for safer storage.
According to OneKey, the recent vulnerability linked to the Milk Sad incident does not compromise the security of its hardware or software wallets. The company clarified that the flaw originated from Libbitcoin Explorer (bx) 3.x, which used the Mersenne Twister-32 algorithm for random number generation. This algorithm relied on a 32-bit system-time seed, making its outputs predictable and vulnerable to brute-force attacks.
Affected wallets included Trust Wallet Extension versions 0.0.172 to 0.0.183, Trust Wallet Core versions up to 3.1.1, and any wallet that integrated Libbitcoin Explorer 3.x. Due to the small seed space, attackers could recreate the same random number sequence and derive private keys generated within specific time frames.

OneKey’s Security Framework and Entropy Validation
OneKey emphasized that its products remain secure because they do not rely on the flawed library. All new-generation hardware wallets use a Secure Element equipped with a True Random Number Generator. This hardware-based system eliminates external dependencies and meets international standards, holding EAL6+ certification for cryptographic assurance.
Even legacy hardware wallets maintain high security. Their random numbers are sourced from an internal TRNG that meets NIST SP800-22 and FIPS-140-2 benchmarks, ensuring reliability and unpredictability.
Additionally, OneKey’s software wallets use secure random number systems based on each platform’s cryptographically secure pseudo-random number generators. The Desktop and Browser Extension versions rely on the Chromium-based WASM PRNG, while mobile wallets use the CSPRNG interfaces from Android and iOS. These systems ensure that private keys remain protected under standard operating conditions.
Recommendation for Long-Term Wallet Safety
However, OneKey cautioned users that the security of software-generated randomness depends on the integrity of the device’s operating system and hardware. If compromised, the randomness quality may degrade. Therefore, the company recommends using hardware wallets for storing digital assets long-term.
To back its claims, OneKey stated that it has tested the entropy quality across all wallet platforms using internationally recognized standards. All tests met cryptographic randomness requirements, and detailed certification reports are available in its Help Center.
