OneKey Pro

The OneKey Pro is a touchscreen hardware wallet that, according to OneKey, supports more than 30,000 coins and tokens through the OneKey App. It has a 3.5-inch IPS colour touchscreen (480 x 800), fingerprint unlock, four secure elements that OneKey lists as EAL6+, and four ways to connect: USB-C, Bluetooth, QR codes and NFC. It was listed at $278 on OneKey’s shop on 14 October 2026. This page is built from OneKey’s documentation; we have not used the device.

Which OneKey wallet is the Pro?

“OneKey wallet” can mean the company’s app or any of its devices. On 14 October 2026 OneKey’s shop listed the Classic 1S at $99, the Classic 1S Pure at $79, the Pro at $278 and the Pro 2, offered as a pre-order, at $299. By price, the Pro sits above the Classic 1S, which OneKey lists with a monochrome 128 x 64 OLED and buttons.

Several values in the datasheet beside this text link to OneKey’s Pro 2 page. That page’s comparison table includes the original Pro, and the same figures (screen, battery, size) appear on the Pro’s own product page.

Who is the OneKey Pro for?

It fits people who hold several kinds of coins and want a phone-style touchscreen signer that can also work over QR codes, with the option of a split SLIP-39 backup. It fits less well if you:

• want a device sold as Bitcoin-only: the Pro is multi-coin, with a switchable Bitcoin-only mode described below;
• prefer a device without a battery or wireless radios.

How big is the OneKey Pro, and how is it used?

OneKey lists 90.1 x 54.4 x 7.6 mm and 65 g, with a 530 mAh battery that charges over USB-C or wirelessly. Input is by touchscreen, and unlocking can use the fingerprint sensor. OneKey describes camera-based QR signing, which it labels air-gap signing: transactions pass between the device and the app as QR codes, with no cable or Bluetooth link. Our air-gapped hardware wallets guide explains what that does and does not protect against. The device can also connect over Bluetooth, USB-C and NFC.

Is the OneKey Pro secure?

OneKey’s product page lists four secure elements rated EAL6+. EAL stands for evaluation assurance level under the Common Criteria, which defines seven levels; EAL6 is named “semi-formally verified design and tested”. A certification level describes how rigorously a chip’s design was evaluated, not which attacks a finished wallet resists. OneKey’s pages we checked do not name the four chips or say what each one does.

Is OneKey open source?

OneKey states “open-source security and design” in a comparison table on its Classic 1S page that includes the Pro. We have not audited which components that covers or under which licences, so treat it as the maker’s claim.

Does the OneKey Pro support SLIP-39 and a passphrase?

Yes to both, according to OneKey. The product page mentions an optional passphrase, and OneKey’s help article on SLIP-39 walks through creating and restoring a SLIP-39 wallet on the OneKey Pro. OneKey’s product comparison also lists 12- and 24-word recovery phrases and 20-word SLIP-39 shares.

The two formats are not interchangeable. The SLIP-39 specification says SLIP-39 and BIP-39 are not compatible, so a SLIP-39 backup can only be restored on a wallet that supports SLIP-39. Before restoring either format on another wallet, check that the destination supports it. Our seed phrase guide covers the difference.

What coins does the OneKey wallet support?

OneKey states more than 30,000 coins and tokens, managed through the OneKey App, which is the companion app named on the product page. We have not counted the list ourselves. For Bitcoin holders, OneKey documents a Bitcoin-only mode for the Pro: you back up the recovery phrase, confirm an update on the device and re-import the phrase, after which only the Bitcoin network is supported. The same process switches it back.

For multisig, OneKey’s Pro product page says the device works with Safe on Ethereum, Squads on Solana and Sparrow Wallet on Bitcoin. We have not tested these integrations.

Has OneKey had security incidents?

In February 2023 the security firm Unciphered demonstrated a physical attack that intercepted communication on the earlier OneKey Mini; OneKey acknowledged it and released a patch. Our records do not establish whether that research applies to the Pro, and we found no documented incident specific to the Pro. The security history below lists the dated entries with sources.

What we could not verify

• When the Pro was launched. Our records do not establish a dated commercial launch.
• The names and roles of the four secure elements.
• Which parts of OneKey’s software and firmware are open source, and under which licences.
• Where the device is manufactured.
• Whether the 2023 OneKey Mini research has any bearing on the Pro.
