OneBullEx Mastercard Enables Digital Assets to Enter Everyday Payments More Naturally

OneBullEx officially launches OneBullEx Mastercard. Users can transfer USDT from their OneBullEx funding account to the card, convert it to USD balance within the card, and use it for online or offline spending at supported merchants and payment scenarios.

OneBullEx Mastercard lowers the threshold for users to access stablecoin payments by simplifying the application process, allowing stablecoins to enter daily consumption more directly, and further extending OneBullEx's AI-native financial services into the actual use of digital assets.

From USDT Balance to Daily Spending

Digital assets are already widely used for store of value, transfers, and cross-border capital flows, but daily spending still relies mainly on fiat currency accounts and traditional card networks. Even if users hold stablecoins like USDT, they usually need to transfer out assets, complete conversion and withdrawal, and then pay via bank accounts or other payment tools.

Taking a user who manages part of their assets with USDT as an example, they may need to pay for overseas software subscriptions, or complete shopping, dining, or other daily expenses while traveling. Without a stablecoin payment card, users often need to switch between digital asset platforms, exchange services, and bank accounts, while considering arrival times, network fees, and conversion costs.

The positioning of stablecoin payment cards is also changing. Data disclosed by Visa shows that stablecoin payment card transaction volume in 2025 was approximately $5.2 billion, a year-on-year increase of 319%. In the second half of 2025, the number of Visa card payments funded by fiat-backed stablecoins exceeded other crypto assets, with an average amount per transaction below $100. This indicates that stablecoin payment cards are gradually moving from occasionally used asset conversion tools into small-value, high-frequency spending scenarios such as subscriptions, shopping, and travel.

OneBullEx Mastercard reduces the intermediate steps required for USDT to enter daily spending. Users can transfer USDT from their funding account to the card on the OneBullEx "My Cards" page; if assets are located in other accounts within the platform, they need to be transferred to the funding account first. After successful top-up, funds will be converted to USD balance within the card for subsequent payments.

Users do not need to withdraw funds to a bank account first, nor do they need to complete external conversions separately before each payment. When spending, the corresponding amount will be deducted directly from the USD balance within the card; if paying in other currencies, the system will automatically convert based on the applicable exchange rate at the time of transaction settlement, and the specific deducted amount can be viewed in the spending records.

Simplified Card Issuance Process, Centralized Subsequent Management

Users can enter the OneBullEx card page, complete registration according to page requirements, and submit a virtual card application. Eligible users can complete card issuance in minutes at the fastest. Currently, each user can apply for up to one OneBullEx Mastercard. After successful card issuance and completing the first top-up activation, users can view the card number, expiration date, CVV, card balance, and card status.

Users can also view top-up records and spending records within the platform, centrally managing card and related fund information without needing to switch repeatedly between multiple independent accounts or services. If abnormal spending, suspected card information leakage, or other risk situations are discovered, users can actively freeze the card on the settings page and contact OneBullEx online customer service for handling.

As a virtual card, OneBullEx Mastercard does not require waiting for physical card delivery. After completing card issuance, activation, and top-up, users can use it for online shopping, membership subscriptions, automatic renewals, and periodic deductions scenarios according to merchant support.

OneBullEx Mastercard can also be bound to WeChat Pay, Alipay, Apple Pay, or Google Pay. Where relevant services are open and devices support them, users can pay at online merchants supporting international card payments, or complete payments using mobile phones in offline scenarios supporting contactless payments.

Accessing the Mastercard network provides an acceptance foundation for the card to enter more payment scenarios. Due to differences in support scopes across different regions, devices, payment platforms, and merchants, actual available scenarios may also differ; users can confirm whether the current scenario is supported based on page prompts when paying.

Launch Benefits Open Simultaneously

To coincide with the official launch of OneBullEx Mastercard, the platform launches a limited launch benefit event from 18:00 on July 27, 2026 to 18:00 on August 23 (UTC+8). Users who successfully apply for a card during the event period, and complete cumulative top-ups exceeding 100 USDT (excluding card issuance fee) and the first valid card spending within 7 days after card issuance, can participate in the event. The deadline for the last batch of users to complete tasks is August 30.

The first 100 eligible users can receive 100% reimbursement of the actual card issuance fee paid. Users who complete valid card spending within 7 days after successful card issuance can also receive random proportion cashback, with a maximum cashback proportion of 10%, each user can receive up to 100 USDT, and the total event cashback prize pool is 5,000 USDT.

In addition, users whose cumulative valid card spending reaches 1,000 USDT during the event period will automatically obtain "1,000 U Spending Lucky Draw" qualification. After the event ends, OneBullEx will randomly draw 8 winners from eligible users, each winning user can receive a 1,000 USDT spending reimbursement reward, with a total reward value of 8,000 USDT.

The event only counts valid spending that has been cleared; transactions involving refunds, reversals, or chargebacks are not included in relevant event statistics. Specific participation conditions, audit methods, and reward distribution times are subject to OneBullEx official event rules.

Rules to Know Before Use

OneBullEx Mastercard is a Mastercard virtual card issued in the Hong Kong region, adopting a card balance spending model, does not provide credit limits, nor does it support overdrafts, ATM cash withdrawals, or transfers to other bank cards. After card issuance, users can complete card top-up, status management, and spending record queries on the OneBullEx platform, and connect corresponding third-party payment services according to actual support.

After funds are transferred to the card, transferring back to OneBullEx accounts is currently not supported; users can arrange top-up amounts according to actual spending plans.

According to current rules, the card issuance fee is 30 USDT. After successful card issuance, users need to top up 20 USDT for the first time to complete activation; this top-up is exempt from top-up fees. Starting from the second top-up, the top-up fee is 2%, collected via internal deduction; USDT is converted to card balance at a ratio of 1 USDT to 1 USD, generating no top-up exchange rate difference.

Each spending transaction will incur a 0.5 USDT authorization fee and a 0.5% spending transaction fee. As long as the merchant initiates spending authorization, an authorization fee may be incurred even if the transaction is not ultimately completed. When paying with non-USD currencies, exchange rate conversion may also be involved; third-party payment platforms, merchants, or acquiring institutions may also charge fees according to their own rules. Users can view the applicable rates and limits at the time through the card page before top-up or payment.

If a merchant initiates a refund, relevant funds will be returned to the card balance, usually taking 7 to 30 working days. Arrival time and refund amount may be affected by merchant processing progress, exchange rate changes, and payment channel settlement; authorization fees generated from original spending are not refundable.

Extending from AI Intelligent Trading to Daily Payments

At this stage, OneBullEx takes AI intelligent trading as the first entry point for users to know the platform and enter a broader ecosystem, and lowers the understanding and use threshold of professional intelligent trading tools through 300 Spartans robots and exchange-level infrastructure.

OneBullEx Mastercard further extends platform services into the payment field. Users can complete fund transfers, card top-ups, status management, and record queries within the existing account system, and use USDT in the account for supported daily spending scenarios. The card connects asset management within the platform with actual payments outside the platform, reducing switching between different accounts and services for users.

As an AI-native financial exchange, OneBullEx is gradually expanding the management and use methods of digital assets within the platform. AI intelligent trading helps users participate in the market and manage assets, while OneBullEx Mastercard adds daily spending uses for assets in the account. With the card launch and simultaneous opening of launch benefits, OneBullEx is also further connecting asset management within the platform with real payment scenarios outside the platform.
