I want to generate my own QR code with my main cryptocurrency addresses without using an online solution, is there maybe a command prompt way or particular piece of software I cam download for this, many thanks.
Also please move to correct section if this is in the wrong place
You could use offline JS libraries either with your browser or in your console.
Requires NodeJS & NPM to be installed
npm install -g qrcode-terminal
qrcode-terminal '1SomeCryptoCurrencyAddressOrPK'
Or in your browser with an offline library
Save a copy of the raw qrcode.js file to your computer as a javascript file. https://raw.githubusercontent.com/davidshimjs/qrcodejs/master/qrcode.js
Then simply use it within an html file
<html>
<script src="qrcode.js"></src>
<div id="qrcode"></div>
<script type="text/javascript">
new QRCode(document.getElementById("qrcode"), "1SomeCryptoCurrencyAddress");
</script>
</html>
