Crypto Converter Widget

A crypto calculator for your site: your readers convert between a coin and any of 58 currencies at the live price, both ways, and pick the coin and the currency themselves.

How to add the converter

Build it. Pick the coins, the currency it opens in and the colours, then copy the code.
Paste it. Open your editor's HTML view and paste it where the converter should show, in an article or a sidebar. The script line goes once per page.
Publish. The figures are live as soon as the page is, and they update by themselves from then on.

Where to paste it

WordPress: a Custom HTML block, or the Text tab of the classic editor.
Blogger: switch the post to HTML view.
Ghost: an HTML card.
Webflow: an Embed element.
Wix: Embed code, then Embed HTML.
Squarespace: a Code block.
Your own site: anywhere in the page's HTML.

Medium and Substack do not run scripts: there a widget stays what you pasted.

Questions about the converter

What can readers convert?

The coins you offer, up to 10 from 2,000+ coins, to and from any of the 58 currencies we have a rate for. They type in either box and the other follows; the swap button puts the currency on top.

Which prices and rates does it use?

The coin's live price, as our coin pages show it, and official rates for the currencies: the European Central Bank's reference rates, and a daily reference rate for the currencies the ECB does not publish. Under the boxes the converter says when the price was taken.

Can readers pick the coin and the currency?

Yes. With more than one coin the coin is a menu, in the order you list them, and the currency is always a menu of every currency we have a rate for. It opens on your first coin and the currency you pick.

Can the converter match my site?

It is dark unless you pick light. The code keeps it 420 pixels wide at most; take out the max-width and it fills the box you put it in.

Why does it say "Prices by Coinfolytics"?

That line is the free converter's credit, a link to Coinfolytics. The Investor plan and above can turn it off in the builder.

Can I write the code by hand?

Yes. The converter is a div with data-cf-converter="bitcoin", or up to 10 coin ids separated by commas (each id as in its Coinfolytics address), and the script line once per page. Add data-cf-cur="eur" for the currency it opens in, data-cf-every="15m" for the refresh (5m, 15m, 30m or 1h) and data-cf-theme="light" for light colours.
