Not a duplicate; QR codes have plenty of use cases outside paper wallets.– Mikko OhtamaaCommented Apr 3, 2017 at 10:41

I think I'm conflating "paper wallets" with "QR code". I imagine there are other forms of paper wallets which aren't QR codes. Duplicate removed.– Richard HorrocksCommented Apr 3, 2017 at 10:48

1In what context? Do you want to make you app or site display QR code or do you just need it for your own use one time?– Nicolas MassartCommented Apr 3, 2017 at 12:12

It looks like myetherwallet is producing invalid codes. It should be ethereum:x0... I'm not sure what they are putting in their codes, but it's non standard.– NickJCommented Jul 29, 2018 at 19:16

Try this:
Where:
- chs=300x300 = size
- cht=qr = type
- chl=0x8CCF9C4a7674D5784831b5E1237d9eC9Dddf9d7F = eth address
- choe=UTF-8 = encoding

Some people recommend prefixing this with a scheme Commented Mar 12, 2018 at 15:38

@FullDecent Not sure what you mean, so you have any reference for your comment?– DerekCCommented Mar 16, 2018 at 15:29

I think the simplest way would be to copy your ETH address and paste it in the text field of this website.. http://www.qr-code-generator.com/
With the oficial Ethereum Wallet software you can do it, just need to go to the account and in the right side of the interfice view you have this option => "Show QR-code" click here and the program show you in the screen the QR code for this direccion account.
You can go to https://www.myetherwallet.com/#view-wallet-info and select 'View with Address Only', paste any address, and it'll spit out a QR code (along with some other info)
If you are using Javascript you can use this module (in nodejs or in browser)
Example :
<script src="node_modules/qrcode/build/qrcode.min.js"></script>
<canvas id="qrcodec"></canvas>
<script>
qrcodelib.toCanvas(document.getElementById('qrcodec'), "your eth address", function (error) {
if (error) console.error(error)
console.log('qrcode successfully created');
});
</script>
alternatively you can use this related module dedicated to Ethereum : https://www.npmjs.com/package/ethereum-qr-code
