MothCard is a virtual payment card that draws on a crypto balance. You top up a wallet in the app, move funds onto the card and spend the result like any Visa or Mastercard number, online and through Apple Pay or Google Pay. The pitch is simple: a global card funded in USDT, with no need for a traditional bank account. In practice, much of what you would normally want to check before signing up is not in writing. Fees, limits, the issuing bank and the licences behind the card are not stated on MothCard’s public pages; you only see them once you are inside the app. I have gone through what the company publishes, the App Store listing and the Terms of Service and pulled together what is confirmed, what is missing, and who this product actually suits. The short version is in the verdict below; the longer walk-through starts with who MothCard will and will not issue to.

MothCard works as a payment card spent from a crypto balance

The conditions described here are current as of October 28, 2026.

Verdict

MothCard scores 5.4 out of 10 in my review. The card does what it says on the tin: a virtual Visa or Mastercard, USDT in, fiat out, available through mobile wallets. But the package is light on transparency, and that drags the score down. Acceptance is global in principle, the wallet and card app is available on iOS and Android, and the on-ramp is the stablecoin most people in crypto already hold. The downside is that a lot of ordinary questions — what does it cost to spend, what is the ATM situation, who issues the card, where is the licence — have answers that are either not stated or hidden behind a sign-in. If you already keep USDT on a phone and want a quick virtual number for online checkout, MothCard is plausible. If you need a published fee schedule, a named issuer or a card you can hold in your hand, it is not.

Here is how the score breaks down by criterion.

Criterion Mark Why
Who can get it 6 / 10 Marketed as accepted worldwide, but country and region restrictions exist and are not listed publicly
Cost 5 / 10 Fees for issuing and maintenance are confirmed, but the actual numbers are only shown in the app
Top-up options 5 / 10 USDT is named; other coins and networks are visible only after sign-in
Reliability and complaints 5 / 10 No public incidents found, but the issuing bank and licences are not named
Everyday use 6 / 10 Apple Pay and Google Pay work; the card is virtual and ATM use is not stated
Total 5.4 / 10

Who it suits: anyone who already uses USDT and wants a quick virtual number for online payments, with Apple Pay or Google Pay for in-store checkout. Who it does not suit: anyone who needs a physical card, a published fee schedule, a named bank issuer or a clear answer about licences and custody before they sign up. I would also hesitate to recommend it as a primary card or as a place to park a balance you cannot afford to lose.

Who will they give you the card

The Terms of Service place MothCard under Hong Kong law, and the company behind it, Hong Kong Yunmo Technology Co., Limited, is registered in Tsim Sha Tsui. The marketing on the site says the card is “accepted worldwide,” but the same wording adds that “some countries or regions may have restrictions.” There is no public list of those restrictions; the issuing region is described as depending on the card you pick and is shown inside the app once you sign in. A few cards are selectable in-app, and they have different issuing regions, so the country you actually end up with on the BIN is not something you can check in advance.

The one-time identity check is the next gate. The app asks for one valid personal ID — the type is shown in-app per country — and in some cases a face scan. The App Store rating is 18+, which is the usual floor for a financial product, but the Terms of Service themselves do not state a minimum age. A proof-of-address document is not mentioned. Because the issuing bank and the licences behind the card are not named on the public pages, there is no way to tell from outside whether a given country is excluded for licensing reasons, sanctions reasons, or commercial ones. If you are in a country where card programmes are typically restricted — for example, the United States, where crypto card programmes have been pulled repeatedly in the past, or countries under broad sanctions — I would not assume eligibility until the app confirms it for you personally.

There is also a wider point. The card is sold as global, but the entity behind it is a single Hong Kong company, and the BIN on the card is issued through a partner scheme (Visa or Mastercard, the company says). The scheme sets the rules of the road, and the issuer — whichever bank or e-money institution is actually putting the card numbers on the network — has its own risk policy. That second layer of country rules is what makes a “worldwide” card sometimes decline at checkout. The Terms of Service acknowledge the gap between marketing and reality by leaving the region to the app, which is honest but not very helpful before you commit.

How to get it

The flow described in the app and on the site is: sign in, choose a card, verify your identity, top up the wallet, then move funds onto the card and start spending. Each step is a screen, and each step is gated. There is no physical card to wait for — MothCard is a “crypto virtual card for global payments,” so once your identity is verified and the balance is loaded, you have a card number immediately.

A few practical points follow from the way the flow is described.

The whole flow is, in principle, fast. In practice, the parts that are slowest — the ID check, the network confirmation, the funding transfer — are the parts where a mistake is hardest to fix. A wrong network on a USDT deposit is the classic way to lose funds, and the support channels, while present, do not publish response times.

What it really costs — fees and limits

This is the section where MothCard is at its thinnest. The company confirms that “there are fees for issuing and maintaining a card,” and that is as far as the public information goes. The amounts — the issuance fee, the monthly maintenance fee, the cost per transaction — are described as shown inside the app, not on a fee schedule. If you are the kind of person who decides whether to use a card by reading a fee page first, this is the part that will put you off.

What is known is the shape of the cost, not the numbers.

Fee or limit What is published
Issuance fee Confirmed; amount in app only
Monthly maintenance fee Confirmed; amount in app only
Conversion fee Not stated
FX fee Not stated
ATM fee Not stated
Per-transaction limit Applies; amount in app only
Daily limit Applies; amount in app only
Monthly limit Applies; amount in app only

To put a few everyday payments through the lens of what is and is not known:

The wider point is that a virtual card with no published schedule is not a budget tool. You can only check what you have paid after the fact, by looking at the app history, which does list payments, fees and merchant refunds. If you need to plan a month in advance, this is not the right product.

Top up: how to fund the card

The funding model is the part MothCard does describe. The App Store listing says the wallet is topped up in USDT, and the in-app transfer screen shows which network to use. Other coins and other networks are visible after sign-in, but are not published on the site.

Topping up MothCard starts with a transfer to the right network

The mechanics, as the company describes them, are: top up the wallet, then move funds from the wallet onto the card. The wallet and the card are two balances, shown separately, and that split is what makes the “crypto in, fiat out” feel work — the card never sees crypto, it sees the USDT-denominated balance once it has been converted to the card’s USD settlement.

Two things to know before you send anything.

Beyond USDT, the company’s general rule is “you used the network shown in the App.” That wording leaves the list of supported coins and chains to the app. If you only hold Bitcoin or a non-stablecoin, the conversion rate at the moment of the top-up is the rate you get, and there is no preview of that rate in the published pages. For a card marketed as crypto-funded, this is the area where a bit more transparency would help.

A note on withdrawal. The app’s FAQ advises moving any remaining balance off a card before cancelling it, and moving funds out of both the card and the wallet before deleting the account. The fees for moving funds out are not stated. If you intend to keep using the balance elsewhere, plan that step before you let go of the card.

Paying with it every day

Once the card is loaded, it behaves like any other Visa or Mastercard number. You can punch the digits into a checkout, save them in a browser, or push the card into Apple Pay or Google Pay from the app. The cardholder experience is the part MothCard does describe, and it is the most polished.

A practical day-to-day tip: keep a small buffer on the card. A declined authorisation can leave a hold on the funds for up to about a week, and on a low-balance prepaid card that hold can block the next purchase you actually want to make.

What can go wrong

The honest list of risks for a MothCard user is the list of risks for any crypto-funded card programme, plus the questions MothCard specifically does not answer.

A short list of what I would check first, in order, if I were considering putting real money on a MothCard:

  1. The fee schedule inside the app, with the maintenance fee expressed as a monthly cost.
  2. The card’s issuing country and BIN, and whether that BIN is widely accepted for the kind of payments I want to make.
  3. The name of the issuing bank and the licence it operates under, and whether that regulator has a public register I can search.
  4. The custody model, and what happens to the balance if the company stops operating.
  5. The list of supported networks for the coin I want to use, and the cost of a test transfer before committing a larger sum.

What to take instead

MothCard sits in a small group of crypto-funded virtual cards that are built for online payments and mobile wallets, and where the cost structure is mostly shown in-app. The three alternatives below are the ones that came up in the same research; the score and the gaps are mine.

CardFlow — 4.9 / 10

CardFlow is pitched as “Nigeria’s smartest fintech card platform” and aimed at Nigerians and global users. It is a virtual USD Mastercard, and the site says it is created in about 3 minutes. Creation is described as free, with no monthly fee mentioned; the per-transaction fees are not stated. Funding is in Bitcoin, USDT, ETH or Naira bank transfer, with networks not stated. Cashback is not stated. The card is a virtual-only USD Mastercard, with no physical option, and most of the cost detail is missing in the same way as MothCard.

Where CardFlow differs from MothCard: the audience is openly Nigeria-first, the funding set includes Naira, and the issuance cost is described as free on the public FAQ. Where it is the same: fees, networks and limits are not published.

HyperCard — 4.7 / 10

HyperCard is a prepaid card with a USD or EUR balance. The App Store page says the card works in more than 176 countries, which is a statement about acceptance at the network level, not about who can sign up; the official pages do not publish a country list. The card type and the network are not stated on the App Store page I read, and the App Store page lists no fees. Funding is by depositing crypto such as USDT, BTC or ETH in the app and converting to USD or EUR on the card; networks are not stated. Cashback is not stated.

Where HyperCard differs from MothCard: the App Store description is more forthcoming on the working countries and the funding set. Where it is the same: networks, fees and limits are not on the public pages.

Card.fi — 6.6 / 10

Card.fi is the most transparent of the three. The site says cards ship to 200+ countries, and the terms bar residents of, or orders from, a country subject to sanctions that would prohibit the service. The range is broader: Virtual Classic, Virtual Premium, physical Classic and Premium, and a metal (stainless steel) card; every physical order includes a virtual card. Cards are issued “under licence from the relevant card schemes,” with the schemes (Visa or Mastercard) not named. One-time prices are published: Virtual Classic US$49, Virtual Premium US$249; physical and metal prices are not listed. There is no monthly, annual, inactivity or minimum-balance fee.

Fees are published. Top-up is 1.5% + US$1.00 for Classic, 1% for Premium. FX is 3.5% for Classic, 2.5% for Premium. The conversion fee is shown before each top-up. Funding is 32 coins across 5 networks (Ethereum, Base, BNB Chain, Solana, Kaanch), including USDT, USDC, ETH, BNB, SOL and KAANCH; a deposit address is per card, the rate is the market rate on arrival, and a wrong chain risks permanent loss. Cashback on card spending is published: Classic 0.8% (cap 10 USDT/month), Premium 1%, Metal 1.2% (cap 100 USDT/month, 5,000 USDT) or 2% (cap 250 USDT/month, 20,000 USDT); a 10% headline rate at coffee shops is capped at 10 USDT/month; earn on balances is “up to 18%” on Metal, variable.

Card.fi scores higher than MothCard in this comparison mainly because the fees, the funding set and the country reach are published. Where Card.fi is the same as MothCard: the licences are not named, and a wrong-chain deposit is still permanent. Card.fi is also more expensive to start with (US$49 for a virtual Classic), which is part of why the published fee schedule exists.

In short, if you want the cheapest, most published path, Card.fi is the more honest product, even if it costs more to enter. CardFlow and HyperCard are closer to MothCard in shape, with similar gaps.

Who I would recommend it to

MothCard is a reasonable fit for a narrow reader. If you are already holding USDT on a phone, you want a virtual number for online checkout today, and you are happy to read the fee schedule inside the app rather than on a public page, MothCard will do the job. The presence of Apple Pay and Google Pay means you can also use it in physical stores where contactless is supported, with the same virtual card underneath.

It is not a fit if you want any of the following: a physical card, a published fee schedule before you sign up, a named bank issuer, a regulator you can look up, a clear custody story, an ATM card, or a place to leave funds sitting for months. It is also not a fit if you live in a country where card programmes of this kind have a history of being pulled, because the public information does not give you a way to confirm your country is welcome in advance.

The score of 5.4 out of 10 is a “maybe, with eyes open.” The product does the basic thing it advertises. The reason it does not score higher is the absence of the basic public information that anyone comparing cards would want before signing up.

Frequently asked questions

What is MothCard?

MothCard is a virtual payment card, issued on Visa or Mastercard, that you fund with crypto from inside a mobile app. The company behind it is Hong Kong Yunmo Technology Co., Limited. The card is described for global online payments, with Apple Pay and Google Pay supported.

How does MothCard work?

You sign in, choose a card, pass a one-time identity check, top up the wallet in USDT (other coins and networks are shown in-app), move funds onto the card and spend the resulting fiat balance like any Visa or Mastercard number.

Is MothCard a bank?

No. MothCard is operated by a Hong Kong company, and the card is a programme on the Visa or Mastercard network. The issuing bank is not named on the public pages, so it is not a deposit-taking bank in the way a normal current account is.

Who owns MothCard?

MothCard is operated by Hong Kong Yunmo Technology Co., Limited, registered in Tsim Sha Tsui, Hong Kong. The Terms of Service are governed by Hong Kong law.

Is MothCard available in my country?

The site says the card is “accepted worldwide,” with “some countries or regions may have restrictions.” The exact country list is not published; the issuing region is shown in the app once you sign in and depends on the card you choose.

Does MothCard require KYC?

Yes. The app asks for one valid personal ID (the type is shown in-app per country) and in some cases a face scan. The check is described as one-time and is part of anti-money-laundering and sanctions compliance.

How do I top up MothCard?

Open the app, choose top up, select USDT (or another coin shown in the app), and send from your wallet to the address the app gives you, on the network the app tells you to use. Once the funds arrive, move them from the wallet onto the card.

How do I add MothCard to Apple Wallet or Google Pay?

The app supports Apple Pay and Google Pay, with the exact wallets depending on the card. Add the card to the wallet from the app, follow the issuer’s confirmation step, and the tokenised card is ready for contactless and in-app payments.

Is MothCard safe?

MothCard uses the usual safeguards of a virtual card: app-based 2FA, optional Face ID or fingerprint, card freeze and unfreeze, and a card details view that is hidden when you are not looking at it. What is not stated is the custody model, the name of the issuing bank, or the regulator — those are the gaps to weigh up before you put a balance on the card.

Is MothCard worth it?

If you want a quick virtual card for online payments, already use USDT, and accept that fees and limits live inside the app rather than on a public page, MothCard is workable. If you need a physical card, a published fee schedule, a named issuer or a card you can leave a balance on for the long term, it is not the right product.
