OneKey founder Yishi has launched tampered.app, a free web tool designed to detect physical tampering in hardware wallets. Users can upload circuit board photos for instant analysis without registration or data storage, with current support for OneKey, Ledger, and Trezor devices. The tool demonstrated over 95% accuracy during testing on approximately 400 user-submitted photos. While it effectively flags suspected anomalies, the developers note that a normal result does not guarantee complete device safety.
