U-cards have become increasingly popular recently, but many reviews only cover the official website's promotions: 0 handling fees, up to 8% cashback, and super high credit limits. They seem very attractive, but you'll find that many fees and restrictions are hidden in the details when you actually use them.

This time, we've compiled a list of 16 U-cards, some based on our own user experience, and others referencing community tests and publicly available information.

Therefore, this article will try to explain in one sentence: who this card is suitable for, what its core advantages are, and where its biggest pitfalls lie.

From compaction to pulling: 16 U cards in simple layering

Hang: Can be used as a main card for daily play

EtherFi, Plasma One Card

EtherFi excels in its comprehensive experience: it's free, has zero deposit fees, offers real cashback, allows withdrawals, and the balance continues to earn interest, making it suitable for people who want to use stablecoins for daily consumption in the long term.

The Plasma One Card's advantages include support for Apple Pay, WeChat Pay, and Alipay, making its payment scenarios more suitable for Asian users. It's ideal for those with a passport, who can complete KYC, and who want to use U as everyday cash.

1. EtherFi

EtherFi currently offers a superior overall user experience among U-cards. Its advantages include being free, having zero recharge fees, providing real cashback, allowing the balance to continue earning interest, and enabling withdrawal of funds, unlike some cards where "the money is locked after being deposited."

Based on user feedback, its daily spending experience is quite similar to that of a regular Visa card. Swiping, subscriptions, and offline purchases are all smooth, and the cashback isn't just points, but rather real assets like eETH/wETH. It's more suitable for users who want to use stablecoins for daily expenses without sacrificing capital efficiency.

2. Plasma One Card

Plasma One Card is one of the most popular everyday spending U-cards among Chinese users recently. Its advantages include being relatively compatible with Chinese passports, supporting mobile payment scenarios such as Apple Pay, WeChat Pay, and Alipay, and focusing on cashback and interest-bearing balance.

However, opening an account usually requires an invitation code, an overseas mobile phone number, and proof of address, and the KYC threshold is higher than that of ordinary exchange cards.

Top-tier: Powerful cards with specific application scenarios

Bybit, Bitget, RedotPay, Tria, KAST, MEXC

Bybit and Bitget are more user-friendly for Chinese users, especially in terms of coverage for AI membership subscriptions, WeChat/Alipay binding, and everyday online spending. RedotPay is suitable for large payments, cross-border transactions, travel payments, and ATM withdrawals.

MEXC is essentially a co-branded card of MEXC × ether.fi , with an underlying experience similar to ether.fi , and additional MEXC access and benefits.

3. Bybit Card

The Bybit Card is better suited for users already within the Bybit ecosystem. Its advantages include seamless integration between exchange accounts and card spending, a smooth Apple Pay experience, and attractive subscription benefits and cashback. For those who already have funds in Bybit and frequently use exchange services, this card is easy to use and suitable for everyday small transactions.

The downside is that the funds are held in custody by the exchange, so issues such as account risk control, withdrawal restrictions, and verification of the source of funds need to be considered.

4. Bitget Card

Bitget Cards should be viewed through two different logics: one is exchange cards, which are more focused on platform ecosystem benefits; the other is wallet cards, which are more focused on self-custodied payments.

The exchange card is suitable for users who already trade on Bitget, hold BGB, or have reached a certain level, but there will be a certain transaction fee for each transaction; the Wallet Card has no monthly fee, no annual fee, and no top-up fee, but after exceeding the free quota, a standard card fee of about 1%–2.2% will be generated in different regions.

However, it should be noted that, according to a Fiat24 announcement, starting today, Fiat24 will suspend new account opening services for users in mainland China. As a result, new users in mainland China will also be temporarily unable to apply for a Fiat24 card through Bitget Wallet.

5. RedotPay

RedotPay is more like a tool card for large-amount payments and global usability than a cashback card. Its advantages lie in its wide coverage, large scale, and high usability, making it suitable for people who need to use stablecoin payments in multiple countries and regions.

Based on community feedback, RedotPay is particularly popular in emerging markets and cross-border payment scenarios. Many users don't use it for cashback, but rather for daily expenses, cross-border payments, travel payments, ATM withdrawals, and even as a store of value in an environment of currency depreciation, they use stablecoins to spend directly through their cards.

6. MEXC Card

The MEXC Card needs to be differentiated between the old and new versions. The old version is generally less attractive, with unremarkable fees, benefits, and user experience, making it not very valuable on its own.

What's truly noteworthy is the MEXC × ether.fi Card, which is essentially an ether.fi card with added MEXC bonuses.

Superior Person: Available to ecosystem users

Tria, KAST

Tria is more suitable for high-spending and high-cashback users, but the annual fee and cashback lockout are not very friendly to ordinary users.

KAST is more suitable for players who expect points/airdrops, and is suitable for small-scale participation, but not for heavy investment with high expectations.

7. KAST

KAST is suitable for users who want to participate in new projects, points systems, and potential airdrops at low cost. Its highlights are zero stablecoin deposit fees, a points mechanism, $MOVE rewards, and a tiered cashback design, making it more like a "consumption + farming" combined U card.

The official website currently shows that the Standard card is free, while the Premium/Private cards have higher annual fees, but offer greater cashback and points benefits. The problem is that the higher-tier cards are relatively expensive, and there's still an element of expectation regarding future benefits. They are suitable for ecosystem users, but not for those looking for a low-cost, everyday main card.

8. Tria

Tria is more suitable for users who make large, frequent purchases, especially those who want to earn higher cashback through higher-tier cards. Its highlights include zero top-up fees, high cashback rates for higher-tier cards, and larger cashback limits, making it suitable for paying large bills, travel expenses, or frequent purchase scenarios.

However, Tria's problems are also obvious: the annual fees for higher-tier cards are not low, cashback usually has a lock-in period, and the points and rewards rules are also quite complicated.

NPCs: Available to ecosystem users, but there's no need to specifically rush to play them.

Crypto.com, OKX, Cypher, MetaMask Card

Crypto.com is suitable for existing users within its ecosystem; OKX is suitable for existing OKX users as a free backup card.

Cypher is geared towards high-end users and high-spending scenarios, while the Premium tier focuses on higher credit limits, lower fees, metal cards, and priority support; however, the regular tier has no obvious advantages and is not suitable for ordinary users as their main daily card.

The MetaMask Card is suitable as a backup card for heavy wallet users, but its annual fee and cost-effectiveness are average.

9. Crypto.com Card

Crypto.com Card is a relatively established U-card product that initially attracted many users with its high cashback rates, subscription benefits such as Spotify/Netflix, and airport lounge access.

However, its benefits now increasingly depend on CRO staking or subscriptions, and the benefits available to ordinary users are significantly less attractive than in the early days.

10. OKX Card

The OKX Card is more suitable for existing OKX users as a free backup card. Its advantages include 0 annual fee and 0 top-up fee. After linking it to Apple Pay/Google Pay, spending is relatively smooth, and it can also deduct directly from OKX Pay. However, cashback is mainly based on USDG spending, and the cashback limit for ordinary users is relatively low. There are also certain restrictions on asset and regional support, and it does not support ATM withdrawals.

Simply put, it's suitable for small-amount spending within the ecosystem, but not for use as a primary card for high cashback.

11. Cypher

Cypher targets high-end users, with its main selling points being its credit limit and premium benefits. The Premium tier might be more suitable for those with higher spending limits who want better FX terms or additional benefits. However, for ordinary users, the advantages of Cypher's standard tier are not obvious, and its value is difficult to realize if spending is low.

12. MetaMask Card

The biggest advantage of MetaMask Card is that it can be used directly from the MetaMask wallet, making it suitable for users who are already deeply familiar with MetaMask and accustomed to on-chain wallet operations.

In terms of cost-effectiveness, its advantages are not outstanding, especially the cost of the metal card at $199/year is relatively high, and the cashback and fee structure does not significantly outperform other competitors.

Finished: Not a priority for now.

Solayer, 1inch, Avici, Coinbase

Solayer is more like a loyalty card, with average value for everyday spending; 1inch Card is more like an ecosystem supplement; Avici has a good concept but is still in its early stages; Coinbase Card is okay for US users, but not user-friendly for most Chinese users.

13. Coinbase Card

Coinbase Card is more user-friendly for US users, especially when spending with USDC or USD balances, as the costs are relatively clear and the 0 annual fee lowers the barrier to entry.

Its advantages lie in compliance, high brand recognition, and ease of use for US users. However, its disadvantages are also obvious: the product is clearly biased towards the US market, and non-US users should not consider it as a priority.

14. Avici Card

Avici Card is similar to Crypto Native in concept, focusing on self-custody, multi-chain USDC consumption, and a more on-chain payment experience.

15. 1-inch Card

The 1inch Card is more like a supplementary product in the 1inch ecosystem than a powerful U-card for the general public.

However, if you only look at credit card spending, it's not very attractive: the 1.75% conversion fee and 2% FX will eat up some of the cashback when you actually spend it, so it's not cost-effective.

16. Solayer

It initially attracted a group of players with its Solana ecosystem, sUSD earnings, and Emerald Points, but now the $20/year subscription fee, 0.5% deposit fee, and inability to withdraw balances are quite noticeable restrictions.

The actual experience of using the card in daily transactions feels more like earning points than having a useful spending card. If you're just testing it out with small amounts or looking to snag a potential airdrop, you can keep an eye on it.

In conclusion

Finally, a reminder: the U-card isn't necessarily the best fit just because it offers the highest cashback.

For Chinese users, what's more important is: whether it's possible to open an account, how difficult KYC is, whether it can be linked to WeChat/Alipay/Apple Pay, whether AI tools can be subscribed to, whether funds can be transferred out smoothly, and whether customer service can handle risk control issues.

Therefore, this list is more of a "subjective reference from the perspective of Chinese users" than an absolute ranking.

Some of the content is based on the editor's own user experience, while some references are made to official website information, community tests, and user feedback from platforms such as YouTube and Xiaohongshu. The actual experience may vary depending on region, identity, KYC requirements, app version, and platform policies. Rates, cashback, and eligibility for new accounts may also be subject to change at any time.

The actual card activation experience is subject to the latest rules on the official website and app. Different regions, identities, KYC requirements, app versions, and platform policies will all affect card activation eligibility, fees, cashback, credit limit, and available scenarios.
