OKX Announces Listing of Spark (SPK) for Spot Trading

OKX has announced the listing of Spark (SPK) on its spot trading markets. The listing timeline includes several key events, starting with the opening of SPK deposits at 3:00 pm UTC on June 16, 2025. A call auction will take place from 9:00 am to 10:00 am UTC on June 17, 2025, followed by the commencement of SPK/USDT spot trading at 10:00 am UTC. SPK withdrawals will be available from 12:00 pm UTC on the same day.

Trading Restrictions and Price Limit Rules

To manage market volatility during the initial phase of SPK trading, OKX will implement specific restrictions. For the first five minutes after trading begins, market orders will not be allowed. Additionally, the maximum amount per limit order and the maximum net position per user will be capped at $10,000. These restrictions will be lifted after the initial five-minute period.

OKX will also apply price limit rules for SPK trading. In the absence of a stable index price, closing price-based limit rules will be used. Once a stable index price is available, index-based limit rules will be adopted. The platform may adjust parameters or switch limit price calculation methods based on market conditions without prior notice.

Call Auction Mechanism

The SPK/USDT spot listing will utilize a call auction mechanism, lasting for one hour. During this period, users can submit buy and sell orders at desired prices. The system processes these orders according to call auction rules, calculating an indicative opening price. To maintain market order, the total value of each user’s buy orders during the call auction must not exceed $50,000. In the final five minutes of the auction, users can place orders but cannot cancel or modify them.

Following the call auction, OKX will display the project team’s opening price as the initial price on the trading chart. This price is provided by the token project team based on the project’s valuation and is for informational purposes only.

Spark is a DeFi protocol that empowers the USDS ecosystem, allowing users to earn yield on their stablecoins and participate in the USDS-centric money market. The total supply of SPK is 10,000,000,000. More information about the listing can be found here.
