MothCard is one of the smaller crypto-card names you can stumble across in the App Store: a Hong Kong-registered virtual card, settled in US dollars, that you top up with USDT and spend online or through Apple Pay and Google Pay. It is a thin, deliberately small product. There is no published fee schedule, no named issuing bank, and no public list of supported top-up networks, so almost everything that matters in a card review has to be inferred from the App Store page, the in-app experience and the legal text behind the app. In this review I go through what is published, what is conspicuously missing, and who this card makes sense for, in which case it hurts you, and what to check first.

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

Verdict

MothCard scores 5.4 out of 10. The reason it is not lower is that it does the basics a virtual card needs to do: it is a real Visa or Mastercard number, it works in Apple Pay and Google Pay, and the App Store page is honest that the only top-up coin it mentions is USDT. The reason it is not higher is that everything else is a question mark. Issuing bank, licences, conversion fee, ATM behaviour, country list, and the full list of networks you can send USDT on are all in the in-app screens rather than on the public site. For someone who already uses a card from a larger programme, MothCard adds little. For someone who specifically wants a USDT-funded virtual card from a small provider and is comfortable verifying the rest inside the app, it can be a workable tool.

I would describe the target audience as: online payments with a virtual card funded in USDT. That is also the audience MothCard describes itself to in its App Store description.

Here is the breakdown by criterion.

Who will they give you the card

MothCard’s own position is broad. The site and the App Store description say the card is “accepted worldwide,” with the caveat that “some countries or regions may have restrictions.” There is no public list of excluded countries. The card you end up with has a specific issuing region, which the app shows during signup, and that region can vary depending on which of the in-app card options you choose. Several cards are selectable in the app with differing issuing regions, but the exact list of regions and which cards are available to which customers is something you only see after you install the app.

The legal side of the company is the more concrete part. The Terms of Service start with a clause placing the governing setup in Hong Kong (section 3.1 of the Terms). The operator is Hong Kong Yunmo Technology Co., Limited, registered in Tsim Sha Tsui, Hong Kong. The card-issuing bank or e-money institution is not named in the public documents. No licences are named in the materials I read. That is not unusual for a small programme manager, but it does mean that the “who regulates this” question is harder to answer than for a card issued by, say, a named EMI in Lithuania or the UK.

If you are the kind of person who needs a published regulator and a published issuer on the website before you load a card, MothCard is not built to reassure you. If you are comfortable verifying those things inside the app and on the live card itself, the published coverage is at least plausible.

How to get it

There is no physical card to ship. MothCard is sold as a “crypto virtual card for global payments.” The App Store description is explicit about that. The card is “issued on Visa or Mastercard” and settles in US dollars. The wallet you hold in the app, and the balance on the card, are shown separately.

Signup runs through four steps in the app: sign in, choose a card and verify your identity, top up the wallet, and move funds onto the card.

Identity verification is described as one-time, for AML and sanctions purposes. The marketing line is “just one valid personal ID,” with the document types shown in-app per country. A face scan is required in some cases, and proof of address is not stated as a requirement. The age requirement is also not stated in the public materials, although the App Store age rating is 18+. Beyond the first check, MothCard does not publish tiered KYC levels, so there is no public answer to whether raising your limits means re-doing the check or providing more documents.

In practice, the gap between “one valid ID” and the real KYC experience is where most small-card friction sits. EU rules, for example, ask for name, address, date of birth, nationality and a sanctions check at minimum, with politically exposed person screening layered on top. If you are in a high-risk country, a sanctioned region, or simply a country the app quietly does not serve, you will find out at the document step rather than at the marketing page.

What it really costs: the Fees table

This is the section of the review that has to be the most honest about what is and is not public. MothCard tells you that there are fees for issuing and maintaining a card, but the amounts are only visible inside the app. Transaction fees, conversion fees, ATM fees, FX markups, and the per-transaction, daily and monthly spending limits are all described as “shown in the app” or “refer to the app for the exact amounts,” rather than published. The FAQ in the app mentions a service fee and a minimum on the in-app confirmation page when you send money.

The practical reading is that MothCard is a paid product, not a free one, and that the only way to know what you are actually paying is to read the in-app screens before you confirm a top-up or a card load. The FAQ in the app also advises moving any remaining balance off a card before cancelling it, and moving funds out of the card and wallet before deleting the account. Fees for those withdrawals are not stated.

To make this less abstract, here are three everyday situations and how the published cost picture applies to each.

You buy an online subscription. The card is a Visa or Mastercard virtual number. Settlement is in USD, so there is no foreign-currency conversion at the card level if the merchant charges in dollars. If the merchant charges in another currency, the conversion happens through the card network or the issuer, and the markup is not published. There is no cashback programme, and the FAQ does not mention rewards.

You add the card to Apple Pay or Google Pay. Adding a tokenised card does not itself carry a fee from MothCard. Whether the token is accepted by the wallet depends on the card you chose in the app, since which wallets work is shown per card inside the app. The actual tap-to-pay fee is the same as the card’s own spending rules.

You try to take cash out at an ATM. Behaviour is not stated, and the card is described for online payments. If ATM withdrawals are technically possible, the fees and limits are in the app. Plan on not relying on this card for cash.

How to Top up MothCard

The published top-up story is small on purpose. The App Store page names USDT as the top-up coin. The app’s own line is that other coins and networks are supported, with the network for each one “shown in the app.” Beyond USDT, the public materials do not list which coins you can deposit, which networks you can send them on, or what the deposit fee and minimum are. The only way to see the actual list is in the app, after signup.

The flow itself is the same shape you find in most crypto cards. You top up the wallet, and you then move funds from the wallet onto the card. The wallet and the card balance are kept separate, which is useful if you want to keep a working balance on the card and a larger reserve in the wallet.

A few things to keep in mind when you send USDT in particular, because these come from how USDT works rather than from MothCard’s own rules.

• Network matters. USDT runs on several chains, including Ethereum (ERC-20), Tron (TRC-20), Solana, Polygon, Avalanche and others. If you send USDT on a chain that the in-app deposit address is not set up for, the transfer is, in practice, irreversible, and recovery is at the provider’s discretion with no guarantee.
• You may need a native gas token. On Ethereum, gas is paid in ETH. A wallet that holds USDT but no ETH cannot send, so make sure you keep a small ETH balance if you use ERC-20.
• Tron fees behave differently. Tron’s network uses bandwidth and energy for internal resource pricing, often burning TRX. If you top up via TRC-20, you may need a small TRX balance.
• The wallet and card are not the same thing. Topping up the wallet is not the same as loading the card. The card spends only what you have explicitly moved onto it.

If MothCard in your app shows only USDT, and only on one or two networks, that is the entire funded universe for that card. If you were hoping to load from a Bitcoin or an Ethereum balance, the public materials do not promise that.

Paying with it every day

The everyday experience includes virtual-card spending online, mobile-wallet tokenisation, and the app itself.

The card number is a Visa or Mastercard number. You can use it for online checkouts the same way you would use any debit or prepaid card. Online payments sometimes trigger 3-D Secure, where your bank (here, the unnamed issuer) decides whether to approve the payment or challenge you with a code or a biometric prompt. That step is governed by the issuer, not by MothCard’s front end, and it can be the reason a payment is held up even when the card balance is fine. A 3-D Secure challenge is a normal part of card payments, and a small, lightly used card is more likely to face one.

Apple Pay and Google Pay are supported, with the specific wallets available shown per card in the app. Tokenisation means the real card number is replaced by a device-specific number, and each tap uses a one-time dynamic code. If you freeze the card in the app, that can extend to the tokenised version in the wallet. Some categories, like gambling, are commonly blocked on prepaid and crypto-funded cards by issuer policy, but MothCard’s blocked-merchant list is not stated in the public materials.

The app itself is available on iOS (15.6 and up), Google Play, and as a direct Android APK. The App Store rating was 5.0 from a single rating when I checked on 2026-10-21; the Google Play rating was not obtained. The App Store version history shows an early 1.0.0 release in February (the year is not shown in the listing), with version 2.1.0 more recent. Twelve languages are available on the site: English, Indonesian, Portuguese, Russian, Simplified Chinese, Spanish, Traditional Chinese are the App Store listing languages.

Disputes are not described in the public materials. The app history lists payments, fees and merchant refunds, which suggests you can at least see what happened on the card, but the formal dispute process is not stated. Chargebacks do exist as a concept for card payments, but prepaid-card coverage varies and is not something to assume.

What can go wrong

There are three families of risk to think about, and MothCard sits in an awkward spot for all of them.

Regulatory and counterparty risk. The operator is a small Hong Kong company, the issuing bank is not named, and the licences are not named. That does not mean the card is unsafe, but it does mean there is less public scaffolding to fall back on if the company has a problem. Crypto card programmes have been shut down before: Visa terminated its global agreements with FTX in November 2022, and the FTX US debit card was wound down by its issuer. WaveCrest, a Visa card issuer that supplied several crypto card programmes, was suspended by Visa in Europe in 2018, and all WaveCrest-issued Visa programmes closed. The pattern in those cases was a notice period, then spending and loading stopped, and users were asked to withdraw their remaining balances.

Self-custody trade-off. Because MothCard takes custody of your crypto before you spend it, you are trusting the operator to hold the funds safely. Custodial platforms have a long record of failures, including Mt. Gox (around US$350 million reported stolen between 2011 and 2014), Coincheck (around US$400 million in 2018) and Ronin Network (US$625 million in 2022). If you want to keep the crypto on your own side until the moment of payment, a self-custody-linked card is a different model, but it also means you take the full risk of key loss, phishing and clipboard-hijacking malware.

Operational and everyday risk.

• Card declines, especially online, are common with prepaid and foreign-issued cards because Address Verification Service is mainly offered in the US, Canada and the UK, and is often unavailable on foreign-issued cards. Some merchants also decline prepaid or unfamiliar BINs outright.
• Declines can leave a hold on the card balance that lingers for up to 7 days, even when no money is actually taken.
• The cost picture is almost entirely inside the app. If you do not read the in-app confirmation screens, you may not know what the conversion fee or the deposit fee was until after the fact.
• The contact options are in-app Support, a Telegram bot, and email at [email protected]. Hours are not stated.
• Search results for “MothCard reviews trustpilot reddit” turned up nothing. That is not proof of anything, but it is a thin public footprint to evaluate.

Security on the card itself is conventional: the app can freeze and unfreeze the card, the full card number and CVV are viewable only after an identity confirmation and then hidden again, sign-in is by email, Apple, or Google, and you can add Face ID or fingerprint on top. None of that changes the bigger custody question.

What to take instead

MothCard is not the only virtual card in this corner of the market. If you want to compare, the table below pulls together three alternatives I have read up on. None of them is presented as “better” without knowing your country and your use case; the point is to give you a sense of where MothCard sits.

What stands out when you put them side by side is how similar the disclosure pattern is. Cardex, CardFlow and HyperCard all publish very little about conversion fees, FX markups, and ATM behaviour, just like MothCard. The differences are mostly in the headline feature: Cardex is the only one of the three that says it scans global exchange rates at the moment of payment, and CardFlow is the only one that says the virtual card is free to create. MothCard is the only one of the four that names a single top-up coin (USDT) in its public materials.

If MothCard’s narrow USDT focus and small operator profile are not what you want, Cardex and CardFlow each add a different angle. HyperCard, with its 176-country acceptance claim, is a more international pitch, though that figure is about merchant acceptance rather than customer eligibility.

Who I would recommend it to

Putting it all together, I would suggest MothCard in a fairly narrow set of cases.

• You specifically want a USDT-funded virtual card, and you are happy verifying the network in the app before you send.
• You mostly pay online, and you do not need ATM withdrawals or a physical card.
• You are comfortable with a Hong Kong operator, an unnamed issuing bank, and reading the in-app fee screens yourself.
• You are not parking a large balance in the wallet for a long time, because the custody and counterparty risk of a small, lightly disclosed programme is real.

I would steer you away from MothCard if you need a published regulator on the website before you load, if you want a published fee schedule you can compare to other cards, if you need ATM access, if you need a physical card, or if you are holding a balance you cannot afford to lose. In those cases, a card from a larger programme with a named EMI or bank issuer is the safer default.

A practical first step, before any top-up, is to install the app, pick the card you are considering, and read the issuing region, the conversion fee, the FX fee, the deposit fee, and the daily and monthly limits that show up in the confirmation screens. If those numbers are not acceptable to you, do not load the card, because the public site is unlikely to give you a clearer answer.
