Description
Crypto QR Code WP lets you accept cryptocurrency donations and tips by displaying any wallet address on your site as a clean label and link that reveals a scannable QR code. It works with Bitcoin, Ethereum, Litecoin, Dogecoin, and any other coin: just paste in your public wallet address and the plugin handles the rest.
Save your wallets once on the settings page and reuse them anywhere with a shortcode, a widget, or the block editor. Each cryptocurrency QR code is generated entirely in your visitor’s browser, so nothing is written to your server and there are no external or third party requests.
Perfect for
- Accepting Bitcoin and crypto donations on a blog, portfolio, or nonprofit site.
- Adding a tip jar or donate button with a scannable wallet QR code.
- Showing several cryptocurrency wallet addresses together on one page.
Key features
- A settings page where you manage a library of wallets, each with a ready made shortcode you can copy.
- A click to reveal QR code tooltip that keeps your page tidy.
- A copy button so visitors can copy your wallet address in one click.
- Built in coin presets and icons for Bitcoin, Ethereum, Litecoin, Tether, Dogecoin, Solana, Bitcoin Cash, and Monero.
- A widget and shortcode, so you can place a wallet in posts, pages, sidebars, or footers.
- QR codes generated in the browser. No server side files, no uploads folder, and no third party services.
- An Appearance tab with a live preview, so you can set the QR size, the QR colors, and the tooltip colors and see the result as you design.
- Works with any theme, including block and Full Site Editing themes.
How it works
- Open Crypto QR Code in your admin menu and add a wallet (label, address, and an optional tooltip heading).
- Copy the generated shortcode, for example:
[cqcw_generator heading="Donate" label="BTC" address="bc1qexampleaddress"] - Paste it into any post, page, or widget. Visitors click the address to reveal the QR code.

FAQ
-
How do I add a wallet?
-
Open the Crypto QR Code menu in your WordPress admin, click Add Wallet, enter a label (such as BTC) and your public wallet address, then save. Each wallet shows a shortcode you can copy.
-
How do I use the shortcode?
-
The shortcode
cqcw_generatoraccepts three parameters: heading, label, and address. Example:[cqcw_generator heading="Donate" label="BTC" address="bc1qexampleaddress"] -
Is my wallet address safe to display?
-
Yes. A public wallet address is meant to be shared so people can send you funds. Never enter your private key anywhere.
-
Where is the QR code image stored?
-
Nowhere. The QR code is drawn in the visitor’s browser each time the page loads, so the plugin does not create files or folders on your server.
-
Does it work with the block editor and widgets?
-
Yes. You can use the shortcode in a block, or add the Crypto QR Code WP widget to any widget area.
