Thanks
to the great guys from openpaperwallet (https://github.com/openpaperwallet/openpaperwallet) who designed the notes under CC


This tool lets your generate PDF paperwallet for arbitrary altcoins
using QR-Codes for fast access to the address and the private key.




Howto Create PaperWallet

• Store address and privkey in csv file
     You may select one of three options to generate you wallet.csv file with
     private keys in it. Read the header of the files to adjust the settings to
     your needs.
  • 1_createEmptyPaperWallets**:
            to create new empty wallets using vanitygen
            press ***Ctrl+C*** when You have enough
  • 1_createNewWalletsAndMoveCoins**:
            to create new wallets using the bitcoin daemons and move coins accoring to the settings in that file
       
  • 1_importExistingWallets**:
            load existing wallets from deamons using 'listaddressgroupings'
       
• Uncomment _ONE_ note layout input line in 'paperWallet.tex' (line 41-48)
• Generate the PDF
     

Code:

$ ./2_generatePDF.sh

• Print
• Cleanup:

Kind of niche but I like the ethos and simplicity ... very small dependency basis to get done what needs doing ... and all Open Source if I'm not mistaken?

yep .. all open source.
I may be able to enhance some steps to further reduce dependencies.

python libs requests and json are need to fetch the current balance from blockchain.info .. I could do that using bitcoin-rpc aswell.

Actually extracting existing keys from bitcoind is an interesting idea, I'd recommend to rather go the vanity trail though.

There are some open templates for paper wallets (with single keys), maybe you can use some of these as well?

Yep .. Think so too.

But, i have a script to load generate new addresses .. fill them with 1btc each and then extract them to print on a paperwallet. That was my intention.

You have a link?
It'l be very easy to install multiple different layouts and let the user select

You might get in contact with them, they have nice designs but I have yet to see an easy to use application that generates their printing layouts. Vanitymining might be the cherry on top!

It looks interesting. Following.

The file is gone...

The file is gone...

That was because pdf file should be deleted after printing (of course)
The old example is still there:

did it. Any more good ideas are very welcome :-)

Hey there ... I'd like to include some LTC paper-wallets ... anyone with some sources to (CC) paper wallet layouts ic can include?

[AliceWonder]

Oh this is cool! I will definitely check this out!

[xeroc]

Added a rudimentary version for XPM.

Note so many bill styles are available as of yet. If you have some idea or layout I would be glad to add it.

BTC:   git clone https://github.com/xeroc/LaTeX-PaperWallet.git -b btc
XPM:  git clone https://github.com/xeroc/LaTeX-PaperWallet.git -b xpm

***UPDATE***
Now with BIP 38 support for BTC addresses
