The OKX Card lets crypto users spend stablecoins like USDC and USDG in everyday situations across Europe, using the familiar Mastercard® network. Key Takeaways The OKX Card is a crypto-backed payment card designed for use across the European Economic Area (EEA), allowing users to spend stablecoins such as USDC and USDG via the Mastercard® network. Payments are automatically converted from to euros at the time of purchase, while merchants receive fiat currency. The card offers a transparent fee structure with no transaction or foreign exchange fees, applying only a small 0.1% market spread on conversion. During launch periods, users can benefit from promotional cashback on USDG payments. The OKX Card is built for crypto-native users while remaining simple for everyday use and is issued in line with applicable European regulatory standards.

What is USDG? USDG is a U.S. dollar–linked stablecoin issued by Paxos , one of the world’s largest and most established regulated stablecoin issuers, also known for PAXG , its gold-backed digital asset. USDG is designed to maintain a stable value relative to the U.S. dollar. Stablecoins like USDG aim to provide more predictable pricing than volatile cryptoassets, which makes them particularly suitable for everyday use cases such as payments, transfers, and card spending . By combining blockchain technology with price stability similar to fiat currencies, USDG helps bridge the gap between digital assets and real-world value. USDG can be held, sent, and used within supported applications, including OKX Pay and the OKX Card , without requiring users to manually convert assets before spending.

You now can earn up to 4.1% APY (rate and availability differ by market) on USDG balances, paid out weekly — no staking, no lockups, no hassle. Rewards are available on your USDG holdings on our app if you are in the United States, Australia, Latin America, CIS (excluding Russia and Ukraine) and Southeast Asia.
