ONE store launches ONE Item in-game trading service
Sellers receive ONE Diamond, a store-only currency that can be used in ONE store games and cannot be cashed out.
ONE store launched ONE Item, an item trading service built directly with game companies, on November 3, 2026, according to techm.kr.
Under the system, users can sell game items and receive ONE Diamond, a store-only currency usable in ONE store games. Sellers can list only items held in a linked game account, and listed items are locked while a transaction is in progress. Once a buyer pays, the item is delivered automatically to the buyer's game account; if delivery fails, the payment is cancelled.
ONE Diamond cannot be bought, exchanged for cash or transferred to other users, the company said.
ONE store plans to expand ONE Item to global markets, iOS and the web within November 2026. The company is also recruiting game partners, with a focus on MMORPGs and multiplayer titles where item trading is already active.
Background
In October 2026, ONE store introduced ONE Diamond as a store-only currency alongside an overhaul of its rewards system. Item trading had previously taken place largely through external brokerage sites, which exposed users to non-delivery and account sanctions.
