imKey Pro

The imKey Pro is a card-sized hardware wallet from imKey, the hardware company founded by the team behind the imToken wallet. Your private keys are generated and held on a bank-grade secure element, and every transaction is confirmed on the device's own screen.

Security

• Infineon SLE 78CLUFX5000PH secure element, built on the M7893 security controller platform certified to Common Criteria EAL6+
• EMVCo certified — the certification scheme used for payment cards
• Private keys are generated offline on the device by a hardware random number generator and never leave it
• Dual CPUs cross-check each other for error detection and self-testing
• Full transaction details are shown on the device screen for you to approve before signing
• Every unit carries a serial number you can check against imKey's own verification page

PIN and device binding

• PIN of 6 to 8 digits, which cannot be repeating or sequential
• After five incorrect attempts the device resets itself to factory settings, and you restore from your recovery phrase
• A binding code ties the imKey Pro to one phone, so a device on its own is of no use to anyone else

Specifications

• Screen with four navigation buttons
• Bluetooth for phones, USB-C for computers
• 64 x 38 mm — smaller than a credit card
• 16.2 g
• 33 mAh lithium polymer battery, around four weeks per charge
• PC panel with a zinc alloy shell

Coins and networks

imKey Pro supports 12 mainchains and over 5,000 tokens: Bitcoin, Ethereum, Cosmos, Vaulta, TRON, Nervos, Bitcoin Cash, Litecoin, Kusama, Polkadot, Dogecoin and Filecoin.

Layer 2 networks including Arbitrum, Optimism and zkSync Era are supported, as are EVM-compatible chains such as BNB Smart Chain, Avalanche and Polygon.

Apps and compatibility

• imToken on iPhone and Android, over Bluetooth — this is the app that activates and binds the device, and the one you use day to day
• Rabby Wallet Chrome extension on a computer, over USB-C
• imKey Manager for Mac and Windows, used for firmware and Bluetooth updates

Activation runs through the imToken app, so set the device up with your phone first even if you intend to use it mainly from a computer.

Backup

• 12-word recovery phrase, generated on the device itself
• Follows the BIP39 standard, so it can be restored into any BIP39-compatible wallet
• Two seed phrase cards are included for writing it down

Warranty

1-year limited manufacturer warranty covering defects in materials and workmanship, including screen faults, button failure, charging failure and secure element defects.

Common questions

Do I need the imToken app?
Yes. imToken activates the device, binds it to your phone and is where you manage your assets. imKey and imToken come from the same team, which is why the integration is as tight as it is.

Can I use it from a computer?
Yes. Connect over USB-C to the Rabby Wallet Chrome extension. Firmware and Bluetooth updates run through imKey Manager on Mac or Windows.

What happens if I forget my PIN?
After five wrong attempts the device wipes itself back to factory settings. You then restore your wallet from the 12-word recovery phrase, which is exactly why that phrase has to be written down and kept somewhere safe.

Does it need charging?
Yes. The 33 mAh battery lasts around four weeks per charge and tops up over USB-C.

Is this a card I tap on my phone?
No. The imKey Pro has its own screen and buttons and connects over Bluetooth, so you read and approve each transaction on the device rather than trusting what your phone shows you.

Buying from SIAMBC

SIAMBC has been Thailand's hardware wallet specialist since 2016, with a physical store in Bangkok. Every unit is new, sealed, genuine stock from authorized channels, and support is available in Thai and English.

ONE RULE TO REMEMBER

Anyone who asks for your 12-word recovery phrase is a scammer. No exceptions.

Neither SIAMBC nor imKey will ever ask for it, whatever reason is given — warranty claims, identity verification, firmware updates or account recovery. Those 12 words are the key to your funds. Whoever has them owns your crypto, and it can never be recovered.
