OneKey vs Trezor: which open-source wallet actually fits you?

Comparison by Sharif Ahmad · hands-on testing where available + documented research · How we test

Both are fully open-source, hardware-certified cold wallets — the two names most often mentioned when transparency matters most. OneKey leans on multi-chip redundancy and a modern touchscreen; Trezor leans on a decade of public track record and a lower entry price. We compare the security model, the features and the price.

01

Quick verdict

OneKey
Choose OneKey if…
You want hardware-level redundancy across four separate EAL6+ certified secure elements on the Pro model, a large touchscreen, SignGuard scam detection, and don't mind paying more for it.
Trezor
Choose Trezor if…
You want the longest public track record of any wallet on this site, a lower entry price starting at $59, and Shamir/Multi-share Backup to split your recovery seed across multiple physical shares.
Both wallets are fully open-source — the real choice is whether you value OneKey's newer hardware redundancy and touchscreen, or Trezor's decade of public scrutiny and lower starting price.

In short: OneKey

OneKey is a touchscreen hardware wallet with fully open-source firmware and companion app, independently verifiable unlike closed-source competitors. The Pro model uses four separate EAL6+ certified secure elements rather than just one, and adds a SignGuard layer that flags risky transactions before you approve them. It has been SlowMist-audited, though one older, discontinued model was the subject of a publicly documented hack.

In short: Trezor

Trezor is the original hardware wallet, launched in 2014, with entirely open-source firmware and companion app that anyone can independently review. The current Safe 3, Safe 5 and Safe 7 models all ship with a certified EAL6+ Secure Element — hardware protection its earliest models lacked — starting at $59 for the Safe 3. It supports Shamir/Multi-share Backup to split a recovery seed across multiple physical shares. An August 2026 breach at a fulfilment partner is a recent negative worth knowing about, though Trezor says no wallets or devices were compromised.

FAQ

Are OneKey and Trezor both really open-source?

Yes — both companies publish their firmware and companion apps as open-source, independently reviewable on GitHub, which sets them apart from closed-source competitors like Tangem or SafePal.

Which is cheaper?

Trezor's entry-level Safe 3 starts at $59, versus $79 for OneKey's Classic. OneKey's Pro model, with its touchscreen and four secure elements, rises to $278.

Which has better hardware security, OneKey or Trezor?

OneKey's Pro model uses four separate EAL6+ certified secure elements rather than one, which is a meaningful redundancy advantage. Trezor's current Safe 3, Safe 5 and Safe 7 models each ship with a single certified EAL6+ Secure Element — a newer addition that closed a gap its earliest models had.

Which has the longer track record?

Trezor, by a wide margin — it launched in 2014 and effectively created the hardware-wallet category, giving it over a decade of public, adversarial security research. OneKey is a newer entrant with a shorter public history.

What happened with Trezor's August 2026 breach?

A fulfilment partner Trezor uses was breached in August 2026. Trezor has stated that no wallets or devices themselves were compromised as a result, but it's a recent incident worth weighing against Trezor's otherwise long track record.
