Launch Schedule for USDG/USDT Trading

- Call Auction Period: June 11, 2025, 8:00 PM – 9:00 PM (UTC+8)

👉 Discover how OKX’s call auction system ensures fair price discovery before market open.
This phased approach allows users to place bids and offers ahead of the official listing, helping establish a balanced opening price based on real market demand.
Risk Control Measures at Market Open
To protect traders from extreme price swings in the first moments of trading, OKX will enforce temporary restrictions for the first five minutes after trading begins:
- Market orders are disabled — Only limit orders can be placed.
- Maximum order size: Each limit order capped at $10,000.
- Net position limit per user: No single account may hold a net position exceeding $10,000.
These safeguards will be automatically lifted five minutes after the market opens, allowing full trading functionality.
Price Capping Mechanism: Ensuring Market Stability
Given the potential for erratic pricing during new listings, OKX employs dynamic price capping rules that evolve as market data becomes more reliable.
Initial Phase: Based on Closing Price
When an index price isn’t yet available or stable, the platform uses a closing-price-based model:
- First minute: Buy orders cannot exceed
Call Auction Clearing Price × (1 + H); sell orders have no lower bound. - Minutes 1 to N (before index stabilization): Buy limit =
Previous minute’s closing price × (1 + H); sell orders remain uncapped. - After N minutes (if index still unavailable): No price caps apply.
Later Phase: Index-Based Price Limits
Once a reliable index is established (typically within minutes), OKX switches to an index-referenced mechanism:
First 10 minutes post-launch:
- Maximum buy price:
Index × (1 + X) - Minimum sell price:
Index × (1 – X)
- Maximum buy price:
After 10 minutes:
- Buy cap adjusts dynamically using recent premium averages and bounded by factors Y and Z.
- Sell floor uses similar logic with downward bounds.
⚠️ Note: Parameters H, X, Y, Z, and N are adjustable at OKX’s discretion based on market conditions. Updates occur in real time without prior notice. Users can monitor live rule status via the platform’s trading interface.
Understanding the Call Auction Process
OKX utilizes a one-hour call auction to determine the initial equilibrium price for USDG/USDT before regular trading commences.
During this period:
- Users submit buy and sell orders at their desired prices.
- The system aggregates all orders and calculates a clearing price that maximizes trade volume.
- Orders are matched based on price-time priority at or near the clearing level.
To maintain fairness:
- Individual users are limited to a maximum buy order total of $50,000 during the auction.
- In the final five minutes, only new limit orders are allowed — modifications or cancellations are disabled.
This prevents last-second manipulation and promotes transparent price formation.
It's important to note: While OKX calculates a reference opening price through the auction, the actual starting price displayed may reflect input from the project team, based on valuation benchmarks. This team-provided price serves as guidance only and does not override user-submitted bids.

Frequently Asked Questions (FAQ)
Q1: What is the purpose of the call auction?
A: The call auction allows OKX to determine a fair opening price by collecting buy and sell interest before trading starts. It reduces volatility and prevents front-running or flash crashes common in traditional launch models.
Q2: Why are there trading limits in the first 5 minutes?
A: These restrictions protect retail investors from sudden price spikes or drops caused by large market orders. By limiting order sizes and disabling market orders, OKX ensures a smoother, more orderly start to trading.
Q3: Can I withdraw USDG immediately after trading begins?
A: No. Withdrawals for USDG will be enabled at 11:00 PM UTC+8, two hours after trading starts. This delay allows the system to stabilize and confirm transaction integrity across blockchains.
Q4: How is USDG different from other stablecoins like USDT or USDC?
A: While all three are dollar-backed stablecoins, USDG emphasizes regulatory compliance, dual-chain availability (Ethereum + Solana), and direct redeemability. Its integration with high-performance chains makes it ideal for DeFi users seeking speed and low fees.
Q5: Will the price cap rules change during trading?
A: Yes. OKX dynamically adjusts its price capping logic depending on index stability. Parameters like H, X, Y, Z may be modified in real time without advance notice to respond to market conditions.
