Since the earlier announcement of Chrome Web Store at Google I/O, the Google team has been working hard to launch the store in October 2010. The first step towards achieving this milestone has been made by making available the developer preview of the Chrome Web Store.

The instructions for apps developers are clearly announced on the official blog post:

Developers can now start uploading apps and experiment with packaging them, installing them in Chrome (using the latest Chrome dev channel) and integrating our payments and user authentication infrastructure.

The Chrome Web Store will bring themes, extensions, games and applications directly to Chrome users thereby making browsing, purchase and installation of all these very easy and intuitive for users. The apps developers in return, will have to pay 5% of the apps price and an additional 30 cents per transaction to Google. But anyhow, you can also sell your apps for free.

To use Chrome Web Store Payments, you must open a merchant account for Google Checkout, and you must associate that account with the store. When someone buys your app using Chrome Web Store Payments, Google charges you a processing fee of 5% + $0.30 per transaction; there are no other transaction costs. The minimum price you can charge with Chrome Web Store Payments is $1.99.

If you are a Chrome app developer, to upload your app you will have to use the upload flow of Google Chrome Extensions Gallery.
