Make Paper Wallets to Keep Your Bitcoin Addresses Safe.

For long-term storage of bitcoins (or giving as gifts) it's not safe to store your bitcoins in an exchange or online wallet. These types sites are regularly hacked. Even keeping a live wallet on your own computer can be risky.

Be your own bank.

By printing out your own tamper-resistant bitcoin wallets and generating your own addresses, you can minimize your exposure to hackers as well as untrustworthy people in your home or office. Just transfer your bitcoins into your new wallets, and use common sense to keep your wallets safe the way you would jewels and ordinary cash. Or give them away!

BitAddress.org Open Source

Why trust this site?

This generator is based on BitAddress.org, the most well established and trustworthy open-source engine for generating addresses using your own browser's JavaScript engine. No crypto-code is run on this web server, and no addresses are transmitted over the Internet. If you don't trust this service (or pseudorandom number generators in general) you can roll dice, shuffle cards, or supply your own "vanity keys". For added security, you can download this wallet generator from GitHub and run it offline.

Canton Becker, the bonafide author of this service, is easily reached for questions and invites you to visit his BitcoinTalk.org trust page »

Flags Christmas Bitcoin Wallets come in 12 different languages, as well as special Christmas and "red envelope" / Chinese New Year designs.

1. Tri-Fold Template

This bitcoin key generator guides you to print both a front side and a back side for your paper wallet. All sensitive details on the front side (the private key and QR code) are folded up and securely taped shut so as to stay hidden. For additional security, you can seal your wallets with the tamper-evident serialized hologram stickers available for purchase on this site—though any sufficiently opaque (light-blocking) tape will work fine.

2. Tamper Resistant

One risk with a paper wallet is that someone with physical access to your wallet may "sneak a peek" at the private key and withdraw your funds without your knowledge. This wallet's folding design and obfuscating security patterns resist "candling" -- the process of shining a bright light through the paper to reveal what's printed inside. Serialized hologram stickers guard against stickers being removed and simply replaced with new ones.

3. Perfect for Giving

Want to give bitcoins to someone who isn't tech-savvy? Need to send bitcoins by mail? Use a pre-loaded paper wallet. The sealed-shut folded design helps to ensure that the recipient won't accidentally reveal the private key. For recipients unfamiliar with bitcoin, the reverse side of the wallet has printed instructions for checking the wallet balance and withdrawing funds.

Secure Wallet Generation & Safekeeping

Helpful tips organized in ascending degrees of paranoia

Keeping it Safe

Water The biggest threat to your wallet isn't an evil WiFi packet-sniffing robot. Your worst enemy is water. If you have access to a laser printer, use it—because laser printers melt waterproof plastic (toner) onto paper instead of using ink. When using an inkjet printer, consider storing your wallet in a zip-sealing plastic bag (like those sold on this site) or printing on waterproof paper, or treating the paper with a clear coat spray like Krylon "Preserve It".

tldr: Treat a paper wallet like cash. If you lose it or if it becomes illegible, the coins are gone forever.

Even the condensation from the outside of a glass set on top of an inkjet print can destroy it.
Here's what a tiny bit of water will do to an inkjet-printed wallet:

Water Damage

Withdrawing Funds

Piggy Bank The private key on this wallet is recorded in typical "Wallet Import Format" (WIF). Many online services (e.g. blockchain.info, coinbase.com) will let you import or "sweep" your paper wallet using this key. Plan on importing your entire balance. Afterwards, discontinue using the paper wallet—as if you were breaking open a piggy bank. If you try to spend or withdraw only a portion of your funds, you risk losing the remaining balance forever.
How to import paper wallets »

tldr:Add funds to your wallet as often as you like, but withdraw them all at once—otherwise your balance may disappear forever.

Going Offline

Download Generator from GitHub Your wallet may be vulnerable to prying eyes when you are generating the keys and printing them out. Although the wallet generator on this website is SSL-encrypted, it's still possible for someone to be snooping on you. (For example, your computer might have malware that broadcasts your screen to a remote location.) The most important safety measure is to go offline and run the javascript wallet generator on your own computer instead of this website.
Here's how »

tldr:Download the ZIP file or get the Ubuntu LiveCD and run the wallet generator with your Internet connection turned off.

How to run this wallet generator offline

You can order the Ubuntu LiveCD from this site (which comes with the wallet generator securely pre-installed)

OR:

  1. Download the wallet generator from GitHub as a ZIP file to your computer.
  2. Turn off your Internet connection. (Power off the modem!)
  3. Extract the ZIP file and drag the HTML file inside of it onto Safari, Firefox, or Chrome (not Intenet Explorer.)
  4. Print out your wallet(s).
  5. Reboot your computer and power cycle your printer before going back online.

Destroying Cache Files

Trash The problem with printing out secure documents—even if your computer is 100% virus/trojan free—is that your printer driver and/or operating system may be keeping copies of the documents you print in some sort of "spool" or print queue. If a hacker or virus gets into your computer and knows to look for these cache files, then they can get your private keys and "sweep" your wallets. Here are some tips on how to securely delete your printer "spool" files.

tldr: Learn how to delete your printer cache files after printing secure documents.

How to delete pesky printer cache files

Macintosh:

  1. Enable 'FileVault' to encrypt your filesystem so that cache files cannot be 'undeleted'.
  2. Set up a symbolic link from /private/var/spool/cups/cache/ to a removable media volume (e.g. a SD card) and disconnect it when not in use.

Windows:

  1. Use an encrypted filesystem so that your cache files cannot be 'undeleted'.

Linux:

  1. Use a live-boot CD instead of a regular hard drive OS install. This way when you reboot your computer, all cache files are deleted from memory and no jobs are ever written to disk.

Using a Clean OS

Clean CD If you've got loads of applications on your computer, or if you use your computer for "risky behavior" (like installing freeware or visiting java / flash websites) consider dedicating a computer (or at least a bootable partition / thumbdrive / "live CD") for paper wallet printing. Never take that install online. Transfer the wallet generator ZIP file from GitHub to your clean OS using a thumbdrive or other non-networked method.

tldr: Run the wallet generator on a dedicated offline computer / OS.

Using a Dumb Printer

Dumb Printer Some advanced printers have internal storage (even hard drives) that preserve copies of printouts. This is a risk if someone gets access to your printer, or if you dispose of your printer. There is also the possibility that a smart enough printer can be hacked. This isn't quite tinfoil-hat level paranoia, as we've seen examples in the wild of viruses that rewrite the firmware of non-computer devices indirectly connected to the Internet. If this concerns you, don't use a fancy printer, and never let your printer have access to the Internet or to an Internet-connected computer.

tldr: Smart printers save copies of what they print and may be vulnerable to super-smart viruses. Use a dumb offline printer whose firmware can't be reprogrammed.

Don't Panic

Overwhelmed? Scared silly?

There's no need to follow all of these precautions. If you're just generating some give-away wallets for fun or to store small amounts of bitcoin, relax. Just use the online wallet generator on a trusted computer and secure Internet connection. For storing larger amounts, follow as many of these security precautions as you can.

Why Did You Make This?

I love Bitcoin. I love how it's elegant, functional, philosophical, and radical.

Unfortunately, for folks not steeped in cypherpunk ideology and network security, bitcoins are hard to understand, hard to purchase, and hard to keep safe. The primary purpose of this site is to make it easier to keep your coins safe once you've gone through the hard work of acquiring some.

The secondary purpose of this site is to encourage you to expand the understanding and acceptance of Bitcoin by loading up and giving away these beautiful and fairly idiot-proof paper wallets.

Hey, here's a couple bitcoins. Keep this paper somewhere safe for now, because some day it might be worth a whole lot and you can buy yourself something nice. Enjoy!
