Coming soon to adventurers in Azeroth, the WoW Token is a new in-game item that allows players to simply and securely exchange gold and game time between each other.
The WoW Token was created to give players with lots of extra gold the option to use it to help cover their game time costs, 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.
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.
