Get the Coil Extension

The Coil Extension tells us when and where to stream payments. For the majority of web monetized sites, you'll need to install the extension for payments to occur.

We've partnered with some services that allow you to sign in with Coil or link your Coil account (like Imgur). When signed in or linked with Coil, you don't need the extension to access their web monetized content. However, you'll need the extension to access all web monetized content outside of these services.

How it works#

As you browse, the extension checks whether each page is web monetized by looking for a snippet of code called a Web Monetization meta tag. This snippet must contain a valid payment pointer.

When a page is web monetized, the extension shares an ephemeral (short-lived) identifier with the site, which the site uses to verify that your browsing session is monetized (i.e, that you're a Coil Member). The identifier is random on every page load.

Then, the extension uses the payment pointer to request a temporary, encrypted payment address from the creator’s wallet provider. The extension sends the payment address to Coil's servers, then we stream micropayments over Interledger to the address.

As long as you're active on the page, the extension will continue streaming payments. The extension stops paying if you leave the page, background the page, or are inactive on the page for long enough.

You can click the extension to get more information.

You can also tell if the extension is paying based

extension with no status icon You are signed in to your Coil account and the page is not web monetized. Coil is not paying.

extension with green outline on status icon You are signed in to your Coil account and the site is web monetized. Coil is initializing.

extension with solid green status icon You are signed in to your Coil account and the site is web monetized. Coil is paying.

extension with solid red status icon There are a few reasons why you'd see this status. The most likely reason is that you are not signed in to your Coil account, so Coil is not paying. Click the extension to see if it opens to the Coil sign in page.

If you are signed in to Coil, then Coil is not paying. Reasons can include:

  • Your account is missing a payment card
  • Your free trial ended
  • Your latest payment failed so your membership didn't renew
  • You have a free Creator account

Browser permissions#

What we ask for#

When you install the Coil Extension, you’re asked to grant the extension certain permissions for it to work. The permissions it requests depends on your browser, and can sound excessive or even scary. For example:

  • The Chrome, Brave, and Edge extensions want permission to read and change all your data on the websites you visit.
  • The Firefox extension wants permission to access your data for all websites and access browser activity during navigation.

If you dig deeper into Firefox’s “access your data” permission, you’ll see statements like, “Extensions requesting this permission might...read and write details of your username and password.” These descriptions are written by each browser provider and are meant to cover a variety of scenarios.

Why we ask for it#

In short, we ask for these permissions because browser providers don't offer a better choice.

Since browser providers don’t offer a permission that’s specific to how our extension works, we have to use pieces of what's already available. This means we have to use permissions that ask for more than we need and use. That’s the big reason why our extension is open source. You can check the source code to see what it’s doing: https://github.com/coilhq/web-monetization-projects/tree/master/packages/coil-extension. Our extension does not access, record, or transmit any personally identifiable information (like your name, username, or password) nor does it track your browsing history.
