### 3. Key Definitions

3.1 Prediction Market Contract refers to a binary prediction contract settled based on whether the price of a specific underlying asset rises or falls within a given round's time window. Each round has a fixed start time and end time and is automatically settled upon expiry.

3.2 UP Token / DOWN Token refers to tradable digital tokens representing a User's prediction of the price direction for a given round. Users may trade these tokens at any time prior to settlement and are not required to hold them until settlement.

3.3 Start Price refers to the spot index price of the underlying asset captured by the Platform at the official start of the round's time window, serving as the baseline reference price for settlement. The Start Price is determined at the commencement of the round; Users who place orders in advance cannot know this price at the time of order submission.

3.4 Settlement Price refers to the TWAP calculated based on the spot index price of the underlying asset during a specified period before the end of each round's time window, used for comparison with the Start Price to determine the settlement outcome.

***

### 4. Product Rules

4.1 Trading Direction

Users may trade in either the UP or DOWN direction based on their prediction of the underlying asset's price movement for a given round. The Platform does not support selling tokens in excess of the quantity held; Users may only execute a sell order if they hold the corresponding tokens.

4.2 Pricing Mechanism

The combined price of an UP Token and a DOWN Token always equals 1 USDT. Token prices reflect the market's consensus probability for each directional outcome, with the price range inherently locked between 0 and 1.

4.3 Basic Rules

No leverage, no forced liquidation. Users may sell at any time before settlement. The maximum loss for a User is limited to the principal invested in purchasing tokens.

***

### 5. Settlement Rules

5.1 Settlement Trigger

Settlement is triggered automatically upon the expiry of each round's time window and requires no manual action by Users.

5.2 Settlement Outcome

* If the Settlement Price is greater than or equal to the Start Price, the UP side wins;
* If the Settlement Price is lower than the Start Price, the DOWN side wins.

5.3 Settlement Value

* Winning side: each token is settled at 1 USDT;
* Losing side: each token is settled at 0 USDT (i.e., the token value is reduced to zero).

5.4 Settlement Fee

The settlement fee is charged only to the winning side and is calculated as: Token Quantity × Settlement Price × Settlement Fee Rate. No settlement fee is charged to the losing side.

5.5 Settlement Records

Upon completion of settlement, results are automatically recorded in the User's "Prediction History" without the need for manual confirmation.

5.6 Settlement Review

In the event of external data source failures, abnormal pricing, or system errors, we reserve the right to initiate a settlement review and retain the authority to make the final determination. Such review conclusions are binding on Users.

***

### 6. Fees

6.1 Trading Fees

Prediction market trading fees are independently configured. Maker and Taker fees apply at different rates; fees are charged on both buy and sell transactions, denominated in USDT. Specific fee rates are as published on the Platform and will be announced in advance of any adjustments.

6.2 Settlement Fee

See Section 5.4. The settlement fee rate is a fixed value and does not differentiate between Maker and Taker.

6.3 Trading Volume Aggregation

Prediction market trading volume is counted toward the User's overall platform trading activity and is applicable to event statistics and VIP tier upgrade calculations.

7.4 Risk Disclosure

Before using the Prediction Market, Users must fully understand the following risks:

* Liquidity Risk: When market liquidity is insufficient, Users may be unable to close positions at a reasonable price before settlement;
* Trading Restriction Risk: To prevent malicious market manipulation, trading is suspended for 500 milliseconds prior to settlement, during which Users cannot respond to market changes;
* Baseline Price Uncertainty Risk: When placing advance orders, the Start Price has not yet been determined, and Users must accept this uncertainty;
* Price Manipulation Risk: Under extreme market conditions, the spot index price of the underlying asset may be subject to manipulation, which could affect settlement outcomes;
* Technical Failure Risk: System failures or network anomalies may cause delays in trade execution or settlement irregularities;
* Regulatory Risk: Changes in laws and regulations may result in the restriction or termination of the Services;
* Wallet Security Risk: Users are solely responsible for safeguarding their private keys and mnemonic phrases. We are unable to recover lost access or assets on behalf of Users.

7.5 User Acknowledgment

By connecting your wallet to access or use this Platform, you irrevocably acknowledge and agree that:

* You have fully read and understood the entire content of this Agreement, including all disclaimers and risk disclosures in this section, and you voluntarily accept them;
* You fully understand the high-risk nature of prediction markets, and your participation in trading is based on your own independent judgment and free will, unrelated to any representations or recommendations by the Platform;
