Cold Storage Wallet instructions:

Disclaimer:

If someone gets a hold of your coin and takes off the hologram, they own your private keys to this wallet. Real Crypto has no liability for your lost, stolen or hacked private keys. These instructions are here to help you stay safe but we make no guarantee that this will prevent hackers from obtaining your private keys. We are not liable for any damaged property, injuries sustained or any other negative consequences of following this tutorial. By making a cold storage wallet on a computer and printer that has or will ever be connected to the internet, you must accept a level of risk that your private keys could be compromised. We strongly suggest you make a wallet on a computer that has never been connected to the internet and use a printer with no internet access. A brand new computer or a computer that was just wiped are the safest ways to protect yourself.

We recommend watching our how-to video while following along with this written instruction manual. https://realcrypto.org/media/

The numbers for each step below also corresponds to the number on the video to help you follow along.

 

Items needed:

Computer with access to the internet

Computer that has never been connected to the internet or freshly wiped (recommended but not needed)

Printer and printer paper. Corded laser printer with no access to the internet is preferred.

 

How to make QR Codes for Public and Private Keys

Make sure your computer and printer are free of any malicious software before you start.

You don’t have to make a wallet and can just apply the hologram if you want this for decoration or a collection. If you decide to apply the hologram, still cut out a piece of paper in .37”x37” that is 2 pieces of paper thick. It also looks best to have a QR Code instead of just white paper. We would recommend putting your deposit address there. There is a recessed area in the coin and the hologram will have an air pocket behind it if you don’t have 2 pieces of paper thick behind the hologram

1.  Make a wallet for Monero. Do this by going to: https://github.com/moneromooo-monero/monero-wallet-generator Make sure you are downloading the latest version of the wallet because these wallets are updated sometimes.

3.  Click on: Clone or Download (green button). Click “Download ZIP” and download the file to your computer.

4.  We recommend putting this file on to a USB drive and installing it on a computer that has never been on the internet. We also recommend scanning the USB and files for malevolent code prior to any kind of installation on any device. If you don’t have that kind of computer, you can always use Tails operating system on your computer. Those instructions can be found on our media page as well.

5.  If you decide to use a computer and printer that connect to the internet, disconnect your computer and printer from the internet at this time.

6.  If you’re on a different computer with no internet access now, insert the USB drive.

7.  If you’re on a mac, open the file “monero-wallet-generator.html”. All browsers should work but if you have any trouble, use Google Chrome. Stay away from Safari.

8.  If you’re on a PC, unzip the files and then click “monero-wallet-generator.html.”

9.  This will bring up the page without being connected to the internet and will allow you to create a cold storage wallet.

10.  Create the wallet by clicking “Generate Wallet.”

11.  Click “Show QR Code” under the Public Address section. This will make a popup of your public address as a QR Code.

12.  Screen shot your public address. Be careful when screenshotting to not leave any white space around the QR Code. It doesn’t have to be perfect but get it as best as you can.

13.  Open up the screenshot and print it.

14.  Make sure you are using standard A4 printer paper. If you’re in a different country that uses a different size of paper, play with the scale settings on your printer until your QR Code is 10mmx10mm in size.

15.  For A4 paper size, find the scale section on your printer popup and change the scale to 10 or 10%. The goal here is when it is printed that the QR Codes are .37” (10mm) in size.

16.  Print the page on the highest quality and cut out the deposit QR Code. We recommend printing on a laser printer so the ink cannot run and distort the QR Code. Try to cut it out as close to the edge of the QR code as possible without cutting into the QR code.

17.  Check to make sure the deposit key is fully functioning. We are not liable if there is a problem with your keys not working in the future. Keep in mind that the paper wallet holds your official, public Monero address. This address is comparable to an IBAN of any regular bank account; therefore, it can be published. If you provide your official address to another individual, that person may then send you Monero. However, if a person gets hold of your private key, then he or she can access all of the Monero funds you keep on your Monero paper wallet.

18.  Write down your mnemonic seed and private keys (spend key and view key) on a piece of paper that you can store some place safe.

19.  If you decide to place your private keys on the coin, you will need to write it down on a piece of paper. Do NOT attempt to screenshot or write down this code on your computer because it opens you up to having your private keys hacked. We recommend cutting out a blank piece of paper the size of your deposit address so you can keep it to the correct size. It will be very difficult to write your private key in the space on the small 10mm piece of paper.

20.  Place the deposit address key (QR Code) face down into the clear area of the hologram so you can see it from the front. The orientation of the QR code does not matter as it will scan in any direction. Press down on the QR code to make sure it is adequately stuck to the hologram.

21.  Place the private key (if you are want it on the coin) face down into the recessed area of the coin.

22.  Now carefully place the hologram on to the designated area of the coin ensuring there are no creases or bubbles. The hologram is specifically made to fit perfectly inside the circle frame on each coin. If there are creases that lead to the edge of the hologram, water can seep inside and damage your private keys. The hologram is tamper proof so you cannot take it off once it has been applied without damaging the hologram sticker. It will also leave a film behind on the coin to show the hologram was taken off.  We have supplied an extra hologram in case you mess up the first one. If you need more, you can buy them on our website and we can ship them out in an envelope for minimal shipping costs to you.

23.  Now you need to decide if you want to keep the private keys left on the piece of paper or if you want to dispose of them. If you dispose of them and something happens to your coin or the QR Code didn’t print correctly, your coins will be lost forever. If you dispose of the keys and the encryption password, make sure they cannot be read by anyone sorting through your trash. We recommend going outside and burning all the paper if you decide to dispose of them.

24.  Delete the page that shows your public and private keys and ensure it cannot be recovered. You also need to ensure your printer doesn’t store any data that could be hacked to recover your private keys. The process for wiping your printer’s memory varies so we cannot talk this in detail. Just google it for your respective printer and you should be able to figure it out.

 

You did it!

Hopefully it wasn’t too hard. Remember security is a constant battle.

 

When you print something, there is a chance that the images are being sent unencrypted across your network and stored unencrypted in the printer’s memory even after the printing is complete if you printed via wireless connection. Because printer firmware tends to not be security hardened, it is not inconceivable that a virus could exist either now or in the future that would scan all print jobs for anything resembling a cryptocurrency key and transmit it to an attacker. That is why we recommend using a printer that will never be connected to the internet.
