OneKey founder warns older iPhones have unpatchable chip vulnerabilities

Older iPhones sit at the center of this warning because many crypto users rely on phones to hold wallet access data, including seed phrases and related app access. OneKey founder Yishi Wang is pointing to hardware flaws that cannot be fixed with a software update on the affected devices. The issue is specifically framed around iPhone 11 and earlier models, which makes the warning relevant to users who still treat an older handset as a secure storage device.

For people who use a phone as part of their crypto setup, the practical question is whether a device can still be trusted to protect secrets if it falls into the wrong hands. If a handset has an unpatchable chip weakness, users may need to change how they store wallet recovery material and how they separate everyday phone use from key storage. That shifts attention away from convenience and toward tighter device hygiene for anyone keeping crypto-related data on an older iPhone. (per cryptobriefing.com)

The wider trade-off is between the durability of consumer hardware and the security expectations of self-custody. Crypto wallets depend on users controlling their own keys, but that control is only as strong as the device that protects them. A warning like this shows how a general-purpose smartphone can become a weak point in a system built to avoid dependence on intermediaries.

Still open is how broad the exposure is across older iPhone ownership and what exact device combinations are most at risk. The warning names older models and physical access, but it does not spell out which users have already taken steps to move seed phrases elsewhere. What would settle the question is clearer guidance on affected hardware, attack conditions, and the protective steps OneKey expects users to take.
