What I have found so far:
I was able to easily create a mobilecoin account (i.e. the seed to recover keys belonging to an address) using the mobilecoin-python-cli
This seems to work only, while running an instance of the full-service, providing access to the network.
I started the service like this (command is for the test net!):
./full-service \
--wallet-db /tmp/wallet-db/wallet.db \
--ledger-db /tmp/ledger-db/ \
--peer mc://node1.test.mobilecoin.com/ \
--peer mc://node2.test.mobilecoin.com/ \
--tx-source-url https://s3-us-west-1.amazonaws.com/mobilecoin.chain/node1.test.mobilecoin.com/ \
--tx-source-url https://s3-us-west-1.amazonaws.com/mobilecoin.chain/node2.test.mobilecoin.com/
This will AFAIR not work on an airgapped machine. The full-service seems to require an internet connection and the python-cli requires a connection to the service.
Therefore, I think cold storage on an airgapped machine is not possible currently. (please correct me if I’m wrong).
I have not yet sent mobilecoin to an adress created in this way. (I have no testnet mobilecoins. I read that I should have gotten an email with a testnet coin key. Have never seen this email…)
Assuming you installed the above python command line interface, you can use
$mobcli --help
to see the available obtions:
$mobcli --help
usage: mobilecoin [-h] [-v] {start,stop,create,rename,import,export,qr,remove,list,history,send} ...
MobileCoin command-line wallet.
positional arguments:
{start,stop,create,rename,import,export,qr,remove,list,history,send}
Commands
start Start the local MobileCoin wallet server.
stop Stop the local MobileCoin wallet server.
create Create a new account.
rename Change account name.
import Import an account.
export Export seed phrase.
qr Show account address as a QR code
remove Remove an account from local storage.
list List accounts.
history Show account transaction history.
send Send a transaction.
optional arguments:
-h, --help show this help message and exit
-v, --verbose Show more information.
obvisouly with
mobcli create
you’ll create a new account.
The seed and everyting you need to back this up, you can put out to a file using
mobcli export YOUR_ACCOUNT_NAME
with YOUR_ACCOUNT_NAME as seen after (or set during) creation.
With
mobcli list
you can see all your accounts and the balance of all accounts.
When I find the time, I’ll test with actual coins.
For offline storage you could create an address once, back up the file you create with mobcli export ... and note down the address for receiving mob.
Use the address for sending MOB to yourself and never access your seed file again until the day you need it again, if that is what you want?
Edit: I wanted to mention: For the full-service, the latest release is called “Pre-release 1.0.0-pre.1” and I’d rather not use a pre-release version.
However, when there’s a pre relase of 1.0.0, the actual 1.0.0 release will likely be available soon. Maybe there will be more thorough documentation with 1.0.0
