V. Summary:

Through the use of KeepKey wallets, we have experienced a variety of settings, installation, receiving and sending operations. The advantages and disadvantages of this hardware wallet are summarized as follows. The two biggest highlights are the PIN code verification design and the integrated coin exchange function:

KeepKey is utility oriented, workmanship meets wallet requirements, but provides bank-level security in security. Because KeepKey does not have an operating system, the device will not be infected by viruses and malware. Prevents hackers from accessing the key recorder.

The KeepKey display clearly displays transaction information and must manually confirm each transaction using the KeepKey confirmation button.

If the KeepKey is lost or stolen, you can restore the information by restoring the phrase without compromising its private key.

KeepKey is sent, received, and stored through native Chrome applications. It is easier for PC, Mac, and Linux than for installing software. For the Android user, download "MyCelium" from Play Store.


Multi-currency support, supporting up to 54 digital currencies and tokens.

Jinghong's PIN code verification design makes it impossible for App to obtain the true password of the KeepKey wallet while operating on the device, but the disadvantage is that it needs to be adapted to use.

You can exchange coins directly through the built-in ShapeShift integration exchange.

Hardware wallet uses safety rule: equipment should be purchased from the manufacturer or designated dealer; safe preservation of the recovery phase.
