The long-delayed RMAH will now allow players to purchase and sell in-game items using their region's currency. Your home game region will affect which RMAH you will have access to, so if you have created characters to play outside the country registered to your Battle.net account, you will not be able to use the RMAH for those characters.
Only equipment such as armor and weapons is available on the RMAH at this time. Commodities will be added at a later date. In some cases, items may be held for processing. Most items purchased will be available immediately, however.
Using the Battle.net Balance for your Real-Money Auction House transactions requires that you have an authenticator or mobile authenticator on your account. Furthermore, if you choose to use PayPal (not available in all regions), you must use the Battle.net SMS Protection feature.
To access the RMAH, go to your Campaign Screen in Diablo III and select Auction House. Then press the button that shows your region's currency. You can toggle back and forth between the gold AH and the Real-Money one.
The entire announcement from Blizzard is after the break.
