The OneKey Pro is OneKey's flagship: four secure elements, a 3.5-inch color touchscreen, a fingerprint reader, and the choice of signing over USB-C, Bluetooth or fully air-gapped QR codes.

Four secure elements, not one

• Built with four EAL6+ secure elements (TMC THD89), EMVCo certified
• OneKey notes that EAL6+ adds protection against physical tampering and side-channel attacks
• Fingerprint unlock, plus PIN and passphrase

Sign three different ways

• USB-C for a wired connection
• End-to-end encrypted Bluetooth for convenience
• Air-gapped QR signing with an HD camera and flashlight — scan, sign and send without ever connecting

Few wallets offer all three. You can use the convenient path day to day and switch to air-gapped for large transactions.

Common questions

Why four secure elements?
Sensitive operations are spread across multiple certified chips rather than trusting a single one, so compromising one part does not hand over the wallet.

What is air-gapped QR signing?
The wallet displays and reads QR codes through its camera, so a transaction can be signed with no cable and no radio connection at all.

Does the fingerprint reader replace my PIN?
It is a convenience layer on top. Your PIN and optional passphrase still protect the wallet.

How is it different from the Classic 1S?
The Classic 1S is a thin card-sized wallet with one secure element, buttons and a monochrome screen. The Pro is a larger touchscreen device with four secure elements, a fingerprint reader, a camera and wireless charging.

Buying from SIAMBC

SIAMBC is Thailand's authorized OneKey distributor, with a physical store in Bangkok. Every unit is new, sealed and sourced directly. Support is available in Thai and English.

ONE RULE TO REMEMBER

Anyone who asks for your recovery phrase is a scammer. No exceptions.

Neither SIAMBC nor OneKey will ever ask for it, whatever reason is given — warranty claims, identity verification, system updates or account recovery. Those words are the key to your funds. Whoever has them owns your crypto, and it can never be recovered.

Where will you keep your recovery phrase?

Your wallet comes with a paper card to write the words on. That card is one house fire, one flood or one termite nest away from gone — and if the words are gone, so is the crypto. Putting them into steel removes all three risks at once.

• CryptoSafe Lite — from ฿299. Stamp or engrave the words yourself; sets are available with the tools included.
• CryptoSafe Bank — ฿1,290. Industrial grade, with three inner plates and a punch tool in the box.
• CryptoSafe Pro — ฿1,790. Pre-engraved steel tiles slide into place, so there is nothing to stamp. Holds up to 96 characters.
• CryptoSafe Capsule — ฿1,990. A sealed stainless capsule that also resists physical impact.
