> Yishi recommends iOS 27 or later and replacing the phone every one to two years.

OneKey founder Yishi recommends using at least an iPhone 17 with iOS 27 or later as a cold wallet, while describing the guidance as a personal security recommendation rather than an Apple certification or guarantee.

Yishi also recommends replacing the phone every one to two years. The setup involves converting an iPhone into a cold wallet.

Disabling network connections does not eliminate every risk for older phones. They may still be vulnerable if another person gains physical access to the device.
