XT Loan Interest Voucher Instructions & User Guide

1. About Loan Interest Vouchers

2. How to Use Loan Interest Vouchers?

2.1 Access Your Vouchers

• APP: [Homepage] → Tap [Your Profile] (top-left) → [Rewards Hub]
• WEB: [Homepage] → Click [Your Profile] (top-right) → [Rewards Hub]

2.2 Activate Your Vouchers

• Vouchers with activation tasks: Complete the required task to activate the voucher. Then, view it in the "Unused" section.
• Vouchers without activation tasks: Already in the "Unused" section, ready to use.

• If a voucher has been applied to your borrowing order, it moves to the "Used" section.

• If a voucher is not used before expiration, it displays as "Expired".

2.3 Use Your Vouchers

• After you select a loanable asset, any valid discount coupons for that asset will appear. By default, the voucher will not be applied. You need to click and select one (e.g., “20% OFF – USDT Interest Voucher”), with the expiry date.
• 
• After you select a voucher, a discount label appears next to the APR (e.g., “20% OFF”), displaying the original and discounted APR. The label includes duration and maximum deduction. Example: USDT Loan Interest Voucher: Valid for 7 Days, Max Deduction 50 USDT.

• If a borrowing asset or loan pair already has a discount, a discount label (e.g., “20% OFF”) will appear. When a discount voucher is applied on top, users can enjoy a stacked discount. Two labels will be displayed, with the event discount first, and the voucher discount second (e.g., “20% OFF” with explanatory text), connected by "✕" to indicate stacking. The final discount is calculated as: (1 − Event Discount) × (1 − Voucher Discount) 
• Example: (1-20%) × (1-20%) = 64% (36% OFF). The Annual Interest Rate shows both pre- and post-discount rates.

• Vouchers can also be applied when renewing a loan. Display and calculation follow the same logic as the borrowing page.

• If a voucher is applied, the text next to the remaining interest will display the amount already deducted: e.g., Interest Deducted: 0.02283492 USDT.

• The Hourly Rate or Annual Interest Rate shows the final discounted rate, with the voucher label (e.g., “20% OFF”) and the following description: "USDT Loan Interest Voucher: Valid for 7 Days, Max Deduction 50 USDT."

• Once it reaches the deduction limit or the voucher expires, the voucher becomes invalid, and the APR returns to the normal one; the discount label disappears.

• Under [Borrow History], the hourly rate or the annual interest rate is the one at the time of borrowing (after all discounts) and is not subject to active order rate adjustments.

2. Voucher Expiration & Invalid Conditions

3.1 Loan Interest Voucher Expired - Invalid

3.2 Loan Interest Voucher Used - Invalid

• The deduction limit of a loan interest voucher only includes the voucher discount amount and does not include the event discount amount.
• Before the deduction limit is fully used, if the remaining deduction amount is insufficient for the last deduction, the system will deduct up to the remaining amount.
