ASTX Event Contract Explanation

I. What Is an Event Contract?

An Event Contract (Event Contracts) is a trading product based on predicting the price direction of digital assets.

Users select the trading asset, expiration period, and price direction:

• Up
• Down

After the contract expires, the system will automatically settle the contract according to the settlement price specified by ASTX.

• Correct Prediction: The full principal is returned, and a profit of 85% of the principal is earned.
• Incorrect Prediction: The entire principal invested in the trade is lost.

Event Contracts do not require leverage or additional margin. Users can participate in trading based on their judgment of market price movements.

II. Product Features

• Simple and Easy to Understand: Simply predict whether the price will rise or fall at expiration.
• Fixed Return: A correct prediction earns a profit of 85% of the principal.
• Automatic Settlement: The system automatically settles the contract after expiration.
• No Liquidation Mechanism: No leverage or additional margin is required.
• Limited Loss: The maximum loss is the actual principal invested in the trade.
• Multiple Expiration Periods: Supports different expiration periods ranging from 10 minutes to 12 hours.
• Low Entry Threshold: The minimum trading amount is 1 USDT.
• No Early Closing: Once the contract is executed, it cannot be closed early and will be automatically settled at expiration.

III. Profit and Loss

Event Contracts use a fixed 85% profit rate.

Correct Prediction

Return:

Principal + Principal × 85% Profit

For example:

If 100 USDT is invested and the prediction is correct:

• Principal: 100 USDT
• Profit: 85 USDT
• Total Return: 185 USDT

Incorrect Prediction

If the prediction is incorrect, the entire principal invested in the trade is lost.

For example:

If 100 USDT is invested and the prediction is incorrect:

• Loss: 100 USDT
• Total Return: 0 USDT

IV. Settlement Rules

After the contract expires, the system determines the final result based on the ASTX Price Index.

• Select Up, and the settlement price is higher at expiration → Correct Prediction
• Select Down, and the settlement price is lower at expiration → Correct Prediction
• Correct Prediction: The full principal is returned, plus a profit of 85% of the principal.
• Incorrect Prediction: The entire principal is deducted, and the contract value becomes zero.

No fees are charged during the settlement process.

The settlement result is based on the ASTX Price Index at the time of contract expiration.

V. Risk Disclosure

Event Contracts are high-risk trading products. Before participating, users should fully understand the product rules and participate cautiously according to their own risk tolerance.

If the prediction is incorrect, the user may lose the entire principal invested in the trade.

The maximum loss from an Event Contract is the actual amount invested in the trade and will not exceed the principal.
