Any one know how to create a paper wallet for alt currencies - mainly Anoncoin and Unobtanium?

Thanks

A paper wallet is basically a piece of paper with a public address and a private key written on it. If there is no application that will create key pairs for you, then here is a roundabout way. Install a wallet on a computer you don't intend to use and then do a dumpprivkey (assuming it is a bitcoin-qt clone). Then print one of the key pairs on a piece of paper. That should work, but there might be an easier way.

As an Example:

A paper wallet is a way to store Bitcoins that involves printing the Bitcoin addresses and private keys directly on a piece of paper. When done properly, paper wallets are one of the safest ways possible to store Bitcoins

Step 1. Print the Paper Wallet

Open bitaddress.org and click the Paper Wallet tab. Print the page on high quality setting.

Step 2. Download the Android App

If you already haven't already download the blockchain.info android app. You will need to create a new wallet or pair to an existing wallet, follow the on screen instructions.

Step 3. Scan the Addresses from the paper wallet

Bitcoin Addresses come in two parts - public and private keys. We are going to import the public part of the address into the android app. This lets the app view the balance and transactions of an address but cannot spend the funds without scanning the private part.

Open the android app click the menu button on the top bar and choose "Address Book". Again hit the menu button and select "Scan Watch Only Address" and scan the QR Codes on the paper wallet labeled "Load & Verify". Choose a label for the address if you wish.

Step 4. Receiving Coins

You will now see the addresses from the paper wallet in the android app with a (Watch Only) tag. You can receive coins and view your transactions as you would with a regular address.

Step 5. Spending The Coins

Please test spending a small amount before receiving any large payments.

Click the send arrow in the top right. Click the menu button and choose "Custom Send"

Set the from address field to the address on the paper wallet.
 
Enter the recipient and amount to pay. Click Send.

When prompted press ok and scan the qr code labeled "spend" from the new paper wallet.

All Done!

Assuming no errors your transaction will be sent instantly. Note: Since the private key has now been scanned by a device connected to the internet many people would no longer consider the address true cold storage anymore. Depending on how concerned you are you might wish to use each key only once and send the rest of the coins to a new address each time.

Thanks for the response, how do you do a 'dumpprivkey'?
