Odaily News According to the official announcement, OKX stated that in order to improve the trading experience of wallet users, the original ZKDEX "coin-to-coin" and "contract" trading test network products will be upgraded to a unified account and renamed "order book". This upgrade involves updates to the web, app and server, and will provide a new on-chain order book trading experience. Since the original system is deployed on the test network, the assets are test coins and have no actual value, so users do not have to worry about asset losses after the system upgrade. After the upgrade is completed, you need to re-authorize login, receive test coins, and trade. Spot trading and contract trading will share a trading account, and order book trading will also provide contract trading services with USDC as a single currency margin. Please note that the order book service is still running on the test network. The upgrade cycle is from 10:00 (UTC+8) on August 5, 2024 to August 6, during which the ZKDEX coin and contract entrances will be hidden. After the upgrade is completed, the web page will open the entrance on August 6, and the App will also open the entrance as soon as it is released in the app store. The old version of the App will no longer be able to use ZKDEX currency and contract products. Users are expected to upgrade the OKX App to the latest version to ensure normal use.
