Important Notes for EOS Holders
If you still hold EOS tokens that were not automatically swapped, it is essential to initiate a withdrawal and complete the conversion process independently. Failure to act may result in missed access to the new Vaulta (A) ecosystem. For full details on the swap mechanism and eligibility, refer to the official guidelines provided by the project team.
Spot Trading Risk Management Rules
To ensure market stability and protect investors during the initial volatility of a new listing, OKX has implemented specific risk control measures for the first minutes of trading.
Order Restrictions (First 5 Minutes)
During the first five minutes after spot trading begins:
- Market orders are disabled – Only limit orders are allowed.
- Maximum order size: Each limit order cannot exceed $10,000 USD equivalent.
- Net position cap: A single user’s net long or short position cannot exceed $10,000 USD.
These restrictions will be automatically lifted five minutes after trading commences, allowing full trading functionality.
Price Limit Mechanism
OKX employs a dynamic price capping system designed to prevent excessive price swings when market data is unstable.
Price Limits Based on Closing Price (When Index Is Unavailable)
- First minute of listing: Buy orders capped at Call Auction Clearing Price × (1 + H); sell orders have no minimum.
- Minutes 1 to N (before stable index): Buy limit set at Previous minute’s closing price × (1 + H); no restriction on sell prices.
- After minute N (index still unavailable): No price limits apply.
Price Limits Based on Index (When Index Is Stable)
First 10 minutes after listing:
- Buy cap: Index × (1 + X)
- Sell floor: 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)]
- Buy cap:
Note: OKX reserves the right to adjust parameters H, X, Y, Z, and N at any time based on market conditions. Such changes will be implemented without prior notice to maintain platform integrity and fairness.

Understanding the Call Auction Mechanism
The A/USDT trading pair will debut using a one-hour call auction, a proven method for establishing fair and stable opening prices.
During this period:
- Users can place limit orders at their desired price points.
- The system aggregates all bids and asks to calculate a reference opening price.
- A single clearing price is determined based on maximum executable volume.
To maintain market integrity:
- Each user is limited to a maximum buy order value of $50,000 USD during the auction.
- In the final five minutes, users can only place new limit orders — modifications or cancellations are disabled.
This structure prevents last-second manipulation and ensures equitable participation.
After the auction concludes, OKX will use the opening price provided by the Vaulta project team as the official starting price for spot trading. This price is typically derived from the project’s valuation framework and serves as a reference point. However, it does not influence individual order execution prices during the auction phase.

Frequently Asked Questions (FAQ)
Q1: What happens if I didn’t receive my Vaulta (A) tokens?
If you held EOS in your OKX account before the swap deadline and haven’t received A tokens, verify your balance under Funding Account. If missing, contact OKX support immediately — manual swaps are not available after the cutoff.
Q2: Can I trade Vaulta (A) immediately after deposits open?
No. Deposits open at 3:00 PM UTC+8, but spot trading begins at 6:00 PM UTC+8 following the call auction. You can deposit early but must wait until trading goes live.
Q3: Why are market orders disabled at launch?
This measure protects users from slippage and extreme volatility during the critical first moments of trading. Limit orders give traders more control over execution prices.
Q4: Is the project-provided opening price guaranteed?
No. The project’s suggested opening price is for reference only. Actual trading begins based on auction results and market dynamics.
Q5: When can I withdraw Vaulta (A)?
Withdrawals open at 10:00 PM UTC+8 on May 29, 2025 — four hours after spot trading begins. This delay allows for system stabilization and security verification.
Q6: How does OKX decide when to switch from closing-price to index-based limits?
The transition occurs once sufficient market data is available to calculate a reliable index price. This ensures fair pricing while minimizing manipulation risks.
