OneKey Classic 1S

Overview

The OneKey Classic 1S is OneKey's affordable, open-source everyday wallet — a compact device that pairs a secure element with Bluetooth and USB-C for people who want auditable firmware plus mobile convenience without paying flagship prices. It's aimed at the sweet spot of budget buyers who care about open-source verifiability but also want to manage their coins from a phone.

Functionally it's a straightforward hardware wallet: keys are stored on-device behind a PIN, protected by a secure element, and transactions are confirmed on the device before signing. The open-source firmware is the differentiator at this price — you're not forced to trust a closed black box the way you are with some similarly-priced competitors. It supports a broad range of coins through the OneKey app and connects either over USB-C or wirelessly via Bluetooth.

The honest caveats: Bluetooth adds attack surface compared with a wired-only or air-gapped device (your keys never travel over it, but it's a larger surface than a purely wired wallet), and OneKey is a younger brand than Trezor or Ledger. If you want air-gap with no radios at all, the OneKey Classic 1S Pure variant drops wireless entirely, and for a touchscreen you'd step up to the OneKey Pro. But for a budget-conscious buyer who specifically wants open-source firmware with Bluetooth and a secure element, the Classic 1S is a sensible, honest value pick.
