KeepKey

The KeepKey is partially supported by HWI

Current implemented commands are:

  • getmasterxpub
  • getxpub
  • setup
  • wipe
  • restore
  • backup
  • signtx
  • displayaddress
  • signmessage

signtx Caveats

Due to the limitations of the KeepKey, some transactions cannot be signed by a KeepKey.

  • Multisig inputs are limited to at most n-of-15 multisigs. This is a firmware limitation.
  • Transactions with arbitrary input scripts (scriptPubKey, redeemScript, or witnessScript) and arbitrary output scripts cannot be signed. This is a firmware limitation.

Note on backup

Once the device is backed up at setup, the seed words will not be shown again to be backed up. The implementation here lets users know that backup does not work.
