This guide shows how you can create an EOS paper wallet in a secure and easy way. However it will take you a bit longer than the ones for the other cryptocurrencies we have described on this site. But since this is in our opinion the most secure way to build a cold EOS wallet, we think it’s worth it. And like always, we describe the whole process step by step.
What you need:
– A printer which is connected to your PC by wire
Create an EOS paper wallet step by step:
1) Go to https://nodejs.org/en/ and download Node.js for your operating system.
2) Extract the node-v8.12.0.pkg package and just click through the installation process. Of course the version number of the package may change in the future.
3) Open the command prompt program on Windows or the terminal app if you are on MacOS.
4) Type node -v in the command prompt or terminal window and hit enter. If everything went well, you should now see the software version number v8.12.0. Typing in npm -v should yield 6.4.1 accordingly.
5) Now we will create a folder for our project and go to this working directory by typing
mkdir eoskeys
cd eoskeys
6) Following that, we can download the code we need with
npm i eosjs-ecc. This will automatically start the download and installation process.
7) Now we cut the internet connection by unplugging the ethernet cable and/or turning of WiFi.
8) After installation we launch the interactive node shell by typing node.
9) Then we enter the commands
let {PrivateKey, PublicKey, Signature, Aes, key_utils, config} = require('eosjs-ecc'),
let privateWif,
PrivateKey.randomKey().then(privateKey => privateWif = privateKey.toWif()) and
pubkey = PrivateKey.fromString(privateWif).toPublic().toString().
The last command will yield your public key. Copy it to a new text-document.
10) privateWif will then create your private key. Copy it to the text-document too.
11) It’s a good time to delete the eoskeys directory we created above now. Make sure to empty the trash too.
11) Your text-document may look similar to the screenshot below then. Just print it by using a wire connected printer and you finally have your EOS paper wallet.
