OneKey Founder Suggests Using iPhone 17 as a Cold Wallet

OneKey founder Yishi suggested using the iPhone 17 or newer models as a cold wallet, requiring iOS 27 or higher, and changing devices every one to two years. He does not recommend using the iPhone 16 or earlier models for long-term important asset transactions. Even the iPhone 17 with iOS 27 is only the minimum configuration. For long-term storage of large amounts of funds, Yishi prefers using dedicated signing devices that have transparent security designs and can be continuously maintained and used for transaction verification. He pointed out that keeping the phone offline is a precaution, but factors such as hardware, patch levels, condition, password, and wallet key management determine the actual effectiveness of the precaution.
