OneKey Classic 1S Pure

Overview

The OneKey Classic 1S Pure is the most affordable device in OneKey's lineup and takes a deliberately minimal, security-first stance: it strips out all wireless radios. There's no Bluetooth, no WiFi, no NFC — just a wired/air-gapped device with open-source firmware and a secure element. For buyers who like OneKey's open-source ecosystem but want the smallest possible attack surface at the lowest price, the Pure is the pick.

By removing every radio, the Pure eliminates an entire class of wireless attack surface, leaving a device you interact with through its screen and buttons. Keys are held on-device behind a PIN, protected by the secure element, and transactions are confirmed on the device before signing. It runs the same open-source firmware as its siblings and supports a wide range of coins through the OneKey app.

The honest trade-offs are about convenience and scope. Dropping Bluetooth means no cable-free phone management — you accept a more deliberate, wired workflow in exchange for the reduced surface. It's also a basic screen-and-button device rather than a touchscreen, and OneKey remains a younger brand than the long-established names. But for a budget-minded buyer who specifically wants open-source firmware, a secure element, and a strict no-radio design, the Classic 1S Pure is one of the cheapest ways to get exactly that combination.
