# 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](https://github.com/status-im/keycard-cli) and you should get _at least_ version 2.1.1 of their [smartcard application](https://github.com/status-im/status-keycard/releases/download/2.2.1/keycard_v2.2.1.cap)
|
|
|
|
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_v2.2.1.cap && keycard init
|
|
```
|
|
|
|
At the end of this process, you will be provided with a PIN, a PUK and a pairing password. Write them down, you'll need them shortly.
|
|
|
|
Start `geth` with the `console` command. You will notice the following warning:
|
|
|
|
```
|
|
WARN [04-09|16:58:38.898] Failed to open wallet url=keycard://044def09 err="smartcard: pairing password needed"
|
|
```
|
|
|
|
Write down the URL (`keycard://044def09` in this example). Then ask `geth` to open the wallet:
|
|
|
|
```
|
|
> personal.openWallet("keycard://044def09")
|
|
Please enter the pairing password:
|
|
```
|
|
|
|
Enter the pairing password that you have received during card initialization. Same with the PIN that you will subsequently be
|
|
asked for.
|
|
|
|
If everything goes well, you should see your new account when typing `personal` on the console:
|
|
|
|
```
|
|
> personal
|
|
WARN [04-09|17:02:07.330] Smartcard wallet account derivation failed url=keycard://044def09 err="Unexpected response status Cla=0x80, Ins=0xd1, Sw=0x6985"
|
|
{
|
|
listAccounts: [],
|
|
listWallets: [{
|
|
status: "Empty, waiting for initialization",
|
|
url: "keycard://044def09"
|
|
}],
|
|
...
|
|
}
|
|
```
|
|
|
|
So the communication with the card is working, but there is no key associated with this wallet. Let's create it:
|
|
|
|
```
|
|
> personal.initializeWallet("keycard://044def09")
|
|
"tilt ... impact"
|
|
```
|
|
|
|
You should get a list of words, this is your seed so write them down. Your wallet should now be initialized:
|
|
|
|
```
|
|
> personal.listWallets
|
|
[{
|
|
accounts: [{
|
|
address: "0x678b7cd55c61917defb23546a41803c5bfefbc7a",
|
|
url: "keycard://044d/m/44'/60'/0'/0/0"
|
|
}],
|
|
status: "Online",
|
|
url: "keycard://044def09"
|
|
}]
|
|
```
|
|
|
|
You're all set!
|
|
|
|
## 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: "keycard://a4d73015"
|
|
}]
|
|
```
|
|
|
|
3. Open the wallet, you will be prompted for your pairing password, then PIN:
|
|
|
|
```
|
|
personal.openWallet("keycard://a4d73015")
|
|
```
|
|
|
|
4. Check that creation was successful by typing e.g. `personal`. Then use it like a regular wallet.
