Players will be able to purchase a WoW Token through the in-game Shop for real money, and then sell it on the Auction House for gold at the current market price. When a player buys a WoW Token from the Auction House for gold, the Token becomes Soulbound, and the player can then redeem it for 30 days of game time.
The WoW Token was created to give players with lots of extra gold the option to use it to help cover their subscription cost, and give those who want to purchase gold a way to do so from fellow players through a secure, easy-to-use system. The Token will be making its debut in an upcoming patch—in the meantime, check out the FAQ below for details on how it works.
Blizzard hasn’t announced a price for the token yet but says it hopes it will help combat third-party RMT. The token exchanges will be region-locked, and tokens never expire.Blizzard announcement]
