Using the smartcard wallet

Requirements

• A USB smartcard reader
• A keycard that supports the status app
• PCSCD version 4.3 running on your system Only version 4.3 is currently supported

Preparing the smartcard

WARNING: FOILLOWING THESE INSTRUCTIONS WILL DESTROY THE MASTER KEY ON YOUR CARD. ONLY PROCEED IF NO FUNDS ARE ASSOCIATED WITH THESE ACCOUNTS

You can use status' keycard-cli and you should get version 2.1.1 of their smartcard application

You also need to make sure that the PCSC daemon is running on your system.

Then, you can install the application to the card by typing:

keycard install -a keycard_v2.1.cap

Then you can initialize the application by typing:

keycard init

Then the card needs to be paired:

keycard pair

Finally, you need to have the card generate a new master key:

keycard shell <<END
keycard-select
keycard-set-pairing PAIRING_KEY PAIRING_INDEX
keycard-open-secure-channel
keycard-verify-pin CARD_PIN
keycard-generate-key
END

Usage

1. Start geth with the console command
2. Check the card's URL by checking personal.listWallets:

  listWallets: [{
      status: "Online, can derive public keys",
      url: "pcsc://a4d73015"
  }]

3. Open the wallet, you will be prompted for your pairing password, then PIN:

personal.openWallet("pcsc://a4d73015")

4. Check that creation was successful by typing e.g. personal. Then use it like a regular wallet.
