As of Thursday 23 September, anyone in possession of a Developer dashboard account can sign up for a Google Checkout merchant account.
This means that if developers wish to use Chrome Web Store Payments to charge for apps, they have the framework to do it.
One of Google’s software engineer, Qinming Fang, stated that the framework will include the ability to see how your app will appear in the webstore, and if you’re planning to use Chrome Web Store Payments (http://code.google.com/chrome/webstore/docs/index.html#charging) to charge for apps, you’ll need to complete this setup before accepting any payments.
If you already are in possession of a merchant account, you’ll be able to associate it with your items in the store.
Signing up for Chrome Web Store Payments is currently available to developers based in the US, who have an American bank account.
Google has said that it is currently working to enable payments for international developers as well.
