# OneKey Launches Photo Tool to Screen Hardware Wallet Circuit Boards By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/32167 Published: 2026-10-15T01:43:34.000Z Updated: 2026-10-15T01:43:34.000Z Section: Technology > The free checker supports OneKey, Ledger and Trezor devices. Founder Yishi said tests on about 400 user-submitted photos exceeded 95% accuracy. OneKey has launched tampered.app, a free web checker that reviews hardware-wallet circuit-board photos for visual signs of possible tampering, giving users a way to screen a device with an image. Users can submit board photos from OneKey, Ledger and Trezor wallets. The service requires no registration and does not save uploaded images. Its result is a screening signal: a flagged image may show a suspected irregularity, while a scan with no flag does not confirm that the wallet is fully secure. The checker reviews the submitted board image, so a clean result is not an assurance about the entire wallet. OneKey founder Yishi said the tool’s accuracy exceeded 95% in tests involving about 400 user-submitted photos. The release adds an image-based check to OneKey’s hardware-wallet security work. The company has also outlined planned changes to recovery-phrase backups and motherboard communications in its [hardware-wallet safeguards](). ## Links in this article - [hardware-wallet safeguards](https://www.tokenpost.com/news/technology/29464)
