Bulk Paper Wallets

Create Bulk Bitcoin or Litecoin Paper Wallets

  • Generate large number of paper wallets
  • Possible to use different amounts for each wallet (via commandline or CSV import)
  • Possible to use an offline computer
  • Derives all private keys for wallet from one masterkey. So you will be able to restore a wallet if someone lost his wallet. Off course this has some security and trust implications.
  • Uses easy to design Jinja2 template. Use default one provided or update to your own needs

Installation

Uses the BitcoinLib Python Bitcoin Library

pip install bitcoinlib

And libraries to generate PDF paper wallets with Jinja template markup and QR code's

pip install qrcode pdfkit jinja2

And the libraries to generate a PDF from HTML (see https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf for other OS):

apt install wkhtmltopdf

And if you get PIL or Image errors

pip install image
