Keystone to Destroy 18,835 Wallets After Device-Authentication Key Theft

Hardware wallet maker Keystone will destroy 18,835 wallets following the theft of a device-authentication key. Owners of devices that received old keys after Oct. 20 must undergo additional authenticity checks, even if their wallet passes Keystone's online verification. The move matters for traders who rely on hardware wallets for self-custody, since a compromised authentication key undermines trust in device verification and could push some users toward alternative cold-storage options.
