STAY SAFE.
OneKey users are not affected by the recent COLDCARD/Coinkite RNG issue. The issue is specific to COLDCARD’s random number generation implementation, firmware, and related dependencies. OneKey does not use that code, implementation, or dependency stack. When a wallet is created on a OneKey hardware device, the entropy used to generate the recovery phrase is produced entirely on-device. Independent random sources from both the secure element and the MCU are combined, so the process does not rely on a single component. Unlike COLDCARD’s non-EAL-certified architecture, OneKey’s core secure element has passed a rigorous EAL6+ security evaluation, which includes strict requirements for secure random number generation. OneKey firmware is also fully open source and continuously reviewed by the security community. Protecting user assets has always been our highest priority. We continue to invest heavily in security research, testing, and real-world attack defense to help build a safer future for self-custody. 🫡 Stay safe.
