To be eligible for the reward, the participant must opt in to the campaign and cumulatively complete both tasks below during the Campaign Period. The completion of only one of the tasks shall not entitle the participant to any reward.

1. Task 1 — Qualifying Pizza Purchase

• Make a single purchase with the OKX Card of at least 15 USDG (or the equivalent in BRL on the date of the transaction).

• The purchase must be made at a qualifying pizza establishment, namely a pizzeria, pizza delivery service, restaurant, snack bar (lanchonete) or similar food and beverage venue, as identified by the card network and the acquiring bank which processes card payments for the establishment.

• Only the first eligible transaction per user shall be counted toward Task 1.

• The amount spent shall also count toward the cumulative spend required under Task 2.

2. Task 2 — Cumulative Card Spend

• Accumulate a minimum total of 100 USDG (or the equivalent in BRL) in purchases made with the OKX Card during the Campaign Period.

• All settled OKX Card purchase transactions shall be counted, including the qualifying transaction under Task 1.

• Transactions that are reversed, refunded, contested or charged back shall be deducted from the cumulative total.

3. Reward

• Participants who successfully complete both Task 1 and Task 2 shall receive 15 USDG in cashback, credited to the participant's OKX account.

• The promotion is limited to 5,000 (five thousand) eligible participants on a first-come, first-served basis.

• Total reward budget: 75,000 USDG.

• OKX reserves the right not to reward all participants based on the available token stock and to close enrolments earlier if the budget is exhausted before the end of the Campaign Period.

4. General Conditions

• Each OKX account may participate in only one promotional campaign offered by OKX during the same period. If a qualified user registers for multiple promotional campaigns, they will only receive the reward from the last campaign they registered for.

• ATM withdrawals, peer-to-peer transfers, money orders, quasi-cash transactions and any transactions classified as cash advances by the card network are excluded from both tasks.

• The eligibility of a transaction shall be determined based on its authorization date. Transactions authorized outside the Campaign Period shall not be counted, even if settled within such period.

• Transaction amounts shall be converted into their USDG equivalent at the foreign exchange rate applicable at the time of authorization.

• OKX shall not be liable for any incorrect merchant category classification by merchants or acquiring banks; in such case, the transaction shall not count toward Task 1, but may still count toward Task 2.

In the event of any technical issue or error in eligibility verification, OKX reserves the right to distribute the reward within up to 30 calendar days after the end of the campaign.
