⚠️ Your signing device can be compromised before you ever open the box. Supply chain attacks have gotten smarter. Attackers aren't just phishing anymore. They're tampering with devices mid-shipment. Pushing fake apps through app stores/TestFlight and bundling malware inside Windows and Mac installers. The counterfeit looks identical to the real thing. But internally, the chip is built for one job: exfiltrating your seed phrase. Fake "user guides" walk you straight into malicious software that mirrors real verification flows. The compromised device feels legit the whole time. By the time you move assets in, they're already gone. How to protect yourself: → Only buy from official channels and verified resellers. → No real wallet app ever asks for your seed phrase. → Only download companion software from the official site. And most critically: verify your device before you use it. This is what Keystone 3 Pro is built for. Every unit ships with a pre-loaded verification key. Scan the QR code on our official site. Device-generated code accepted = genuine. Fails = tampered. One scan. No guessing. No trust required. Verify everything. Trust nothing by default.
