On June 18, 2025, at 8:00 PM UTC+8, OKX will officially launch two new spot trading pairs on its USD trading zone: SOPH/USD and KMNO/USD. This strategic move aims to support the growing USD-denominated digital asset ecosystem and meet increasing user demand for diversified trading options.
The launch of these new trading pairs reflects OKX’s ongoing commitment to expanding its product offerings and enhancing market accessibility. These pairs will become available for trading, buying, selling, and conversion approximately two hours after the USD orderbook goes live.
Note: The SOPH/USD trading pair will be accessible only in select regions.
Ensuring a Secure and Stable Trading Experience
To protect traders during the initial phase of new token listings—when price volatility is often highest—OKX has implemented a set of spot market risk control mechanisms. These rules are designed to promote fair price discovery, reduce manipulation risks, and safeguard user assets.
Order Size Restrictions
In the first five minutes following the official start of trading:
- Maximum allowed amount per limit order: $10,000 USD equivalent
- This restriction applies to both buy and sell orders
- After the five-minute window, all limits will be automatically lifted
This measure helps prevent large-volume trades from causing sudden price swings that could impact retail investors.

Price Band Controls During Initial Trading Phase
During the early minutes of a new trading pair's debut, price stability may not yet be established. To address this, OKX employs a dynamic price capping mechanism that adjusts based on market data availability.
Phase 1: Index Price Unavailable (Using Closing Price)
When a reliable external index price isn’t yet available, OKX applies a closing-price-based price limit model:
First minute after listing:
- Buy order cap = Auction closing price × (1 + H)
- Sell orders: No minimum restriction
Minutes 1 to N (before stable index is available):
- Buy order cap = Previous minute’s closing price × (1 + H)
- Sell orders: Still unrestricted
After minute N:
- No restrictions on either side
The value of N represents the time needed for sufficient market data to accumulate. Parameters like H (the price deviation threshold) may vary based on market conditions.
Phase 2: Index Price Available (Using Real-Time Index)
Once a stable index price is established, OKX switches to an index-based pricing model for tighter control:
First 10 minutes after listing:
- Buy order cap = Index × (1 + X)
- Minimum sell price = Index × (1 – X)
After 10 minutes:
- Buy cap = Min[Max(Index, Index × (1 + Y) + avg. premium over last 2 min), Index × (1 + Z)]
- Sell floor = Max[Min(Index, Index × (1 – Y) + avg. premium over last 2 min), Index × (1 – Z)]
These formulas dynamically adjust based on real-time market behavior, incorporating recent trading premiums and ensuring smoother price convergence.
Important: OKX reserves the right to adjust parameters (N, H, X, Y, Z) or switch between pricing models at any time without prior notice. Users are encouraged to monitor real-time rule updates directly on the platform.

Why SOPH and KMNO?
While specific project details are subject to change, both SOPH and KMNO represent emerging assets within innovative blockchain ecosystems. Their introduction to the USD spot market enables traders to gain direct exposure using a stable valuation benchmark—offering greater clarity and reduced volatility compared to crypto-to-crypto pairs.
Such listings often attract interest from institutional and retail traders alike due to:
- Clear pricing in fiat terms
- Easier integration with portfolio tracking tools
- Improved tax reporting accuracy
- Enhanced liquidity through centralized orderbooks
As decentralized networks continue to evolve, assets like SOPH and KMNO may play pivotal roles in areas such as modular blockchain infrastructure, data availability layers, or decentralized governance frameworks—though users should always conduct independent research before trading.
Frequently Asked Questions (FAQ)
Q: When exactly will SOPH/USD and KMNO/USD go live?
A: Trading will begin on June 18, 2025, at 8:00 PM UTC+8, with Buy/Sell and Convert functions typically available about two hours after the orderbook opens.
Q: Is there a difference between USD and USDT trading pairs?
A: Yes. USD-based pairs are priced directly against the U.S. dollar and often used in regulated or institutional contexts. USDT pairs use Tether as the quote asset but track USD value. OKX supports both for flexibility.
Q: Why are there trading restrictions in the first five minutes?
A: These safeguards help prevent extreme price swings caused by low liquidity or manipulative orders during the sensitive launch window.
Q: How can I check the current risk parameters like H or X values?
A: Real-time rule details—including active parameters—are published on OKX’s official rules page under /trade-market/info/spot.
Q: Can all users trade SOPH/USD?
A: No. Access to the SOPH/USD pair is limited to certain regions due to regulatory considerations.
Q: Will futures or margin trading be available for these pairs immediately?
A: Typically, derivative products are introduced after spot markets demonstrate sustained liquidity and stability. No immediate plans have been announced.
