Kontigo markets itself as the first international credit and debit card in USDC that earns yield, and the promise is unusual: a card that spends directly from a US dollar stablecoin balance on a public network, with the customer holding the assets. The pitch is built for people in Latin America who save in dollars because their local currency does not, and for anyone who would rather hold a stablecoin than a bank balance. The reality, when you read the terms and the help pages, is thinner. Most of the practical details that a cardholder needs are not stated anywhere on Kontigo’s public pages. Country eligibility, fees, ATM access, mobile wallet support, and even the card network and form factor all sit behind a registration wall or in app screens that the documentation only describes from the outside. This review walks through what Kontigo does say, what it does not, and what that means if you are deciding whether to put the card in your wallet.

Conditions on this page are current as of October 28, 2026.

Verdict

Kontigo is an interesting product idea with limited public disclosure. The score is 4.7 out of 10, and the reasoning matters more than the number. The card suits a narrow reader: someone in one of the Latin American countries listed in Kontigo’s footer who already lives in USDC, is comfortable with a self-custody model, and accepts that most everyday card details will only become visible after installing the app and verifying identity. If you want a clear fee table, a stated country list, an ATM policy, or Apple Pay support spelled out before you sign up, Kontigo does not give you that. The headline features — USDC balance, on-chain transfers, yield — are real, but the documentation around them is light, and the issuer and licences are not named.

You should keep reading if you are considering the card for cross-border spending, dollar savings in a local-currency country, or as a way to spend from a self-custody wallet. You should look elsewhere if you need a published fee table, a clear ATM policy, or a card that states its network and mobile-wallet support up front.

Who will they give you the card

Kontigo does not publish a list of countries where the card is issued. The footer of the site groups Argentina, Bolivia, Brazil, Chile, Colombia, El Salvador, Spain, the United States, Mexico, and Peru under a “Countries” heading, but those entries are not tied to any specific product or to card eligibility. The terms instead say availability depends on the country of residence and that people in sanctioned or high-risk jurisdictions cannot use the service. The practical reading is that the card works for residents of a set of countries that is defined in the app rather than on the marketing site, and that being a citizen of a listed country is not the same as being eligible.

Kontigo, Inc. is incorporated in Delaware, but the terms do not name the card issuer or the BIN sponsor. There is no licence number, no regulator, and no reference to a banking or e-money partner on the public pages. If the card sits on a Visa or Mastercard programme, the network and the issuing bank are not stated. That matters because a card’s eligibility, the protection you get from the issuer, and the rules of the underlying network all depend on who actually issues the plastic.

The terms also require identity verification before using any service, with checks that can include name, date of birth, address, nationality, ID documents, financial information, and sanctions and credit screening. One account per person. There is no card-specific signup flow described on the public site, and processing times, reasons for rejection, and any tiered verification levels are not stated. The developer documentation mentions that deposit methods depend on KYC level, without naming the levels or the amounts. If you are outside the supported residence list, or in a country that a sanctions check flags, you will not get the card. Everyone else will only know whether they qualify after they install the app and start the flow.

How to get it

The public site does not describe a card-specific application process. The terms are written for the broader Kontigo service, and they say identity must be verified before any service is used, with documents that may include name, date of birth, address, nationality, and ID, plus financial information and sanctions and credit screening. The terms also note that a single person can hold one account, which limits anyone who might otherwise run a household through multiple registrations.

What you see in the wild is some marketing language and one third-party Spanish-language piece that talks about a stablecoin card with Bitcoin cashback and a promotional 10% USDC yield. That cashback and yield figure is not confirmed by Kontigo’s own pages and should be treated as a promotional claim rather than a published benefit. The terms are the source of truth, and they are deliberately thin on what the card is in practice.

The terms do not say what form factor the card comes in, whether it is virtual or physical, or which network it sits on. They also do not describe delivery times. Help centre topics include “Niveles Kontigo” (Kontigo levels), Kontigo Cash, Kochinitos, and Kontigo Credit, but the content of those pages is not published on the public site. If you are trying to decide before you sign up, the honest answer is that the information is not there.

What it really costs and fees and fees

The cost section is where Kontigo is least informative. The terms say that fees, commissions, and spreads are shown in the app and may change, and the home page advertises sending, receiving, topping up, and saving in USDC as “without commissions”. That tells you that the on-ramp to a USDC balance inside Kontigo is free, but it does not tell you what it costs to spend that balance at a shop, what the foreign exchange margin is, what an ATM withdrawal costs, or whether there is a monthly fee. Issuance, conversion, FX, ATM, daily, and monthly limits are all unstated in the public material.

A few examples make the gap concrete. Imagine you top up your USDC balance for free, then buy lunch in a cafe in Mexico City that charges in Mexican pesos. The card needs to convert USDC to pesos at the point of sale, and the rate that gets applied is whatever Kontigo shows in the app at the time. The terms reserve the right to set that rate and to change it, and they do not commit to a margin or a reference rate. If you then travel to Madrid and use the same card at a restaurant, the conversion path is from USDC to euros through whatever rate and fee combination the app applies, again with no public number to compare against.

Cash is a similar story. The terms do not describe ATM access, so the only honest answer to “what does an ATM withdrawal cost?” is that it is not stated. Daily and monthly limits for the card are not published either, and the developer documentation only says that deposit methods depend on the KYC level, without amounts. The cost of using the card is therefore something you find out by reading your own statement after each transaction, not by reading the pricing page before you sign up.

The broader risk is the typical stablecoin-to-fair-money conversion margin, which can run from a fraction of a percent to a few percent depending on the route. Without a published fee, you are trusting that Kontigo’s app rate is competitive, and you can only verify that by comparing the app’s quoted amount with the rate on a public screen when you spend.

How to top it up

Top-up is the part of Kontigo that the site describes most clearly, even if it is still incomplete. The card spends from your USDC balance, and the app runs on Base, a low-fee Ethereum layer-2 network. USDC on Base is what you transfer in to fund the card. The site also says that topping up in USDC is “without commissions”, which means there is no Kontigo fee on the top-up itself; you still pay the underlying Base network fee, which is paid in ETH and is set by the network rather than by Kontigo.

The terms are more careful than the home page. They allow Kontigo to hold liquidated balances in a fiat currency it chooses (for example USD), and they say that digital assets can be transferred to external wallets when that feature is available, with a reasonable period such as 30 days after account closure to instruct a withdrawal. If you do not withdraw, the terms let Kontigo sell the assets and hold the proceeds in a fiat currency it chooses, without paying interest. Closing the account requires no pending obligations and either a zero balance or a withdrawal already instructed.

Three practical points fall out of this. First, you need ETH on Base in the wallet you top up from, because the network fee is paid in ETH even when the asset you are sending is USDC. If you only hold USDC, you cannot move it. Second, the on-chain nature of the top-up means a transfer to the wrong network, or to an address of a different network, can be lost; blockchain transfers are not reversible. Third, withdrawal of the underlying crypto is at Kontigo’s discretion, and the final cash-out happens in a currency Kontigo chooses. There is no published support for top-up in USDT, in fiat by bank transfer, or in non-Base networks.

Paying with it every day

The day-to-day picture is the least developed part of Kontigo’s public story. The site describes the card as the “first international credit and debit card in USDC that earns yield”, and the footer groups it with hybrid, credit, and debit cards without explaining the difference. The form factor — physical, virtual, or both — is not stated. The card network is not stated. Apple Pay and Google Pay support are not stated. Blocked merchant categories are not stated.

The marketing language is about yield, not cashback: the card “earns yield”, with no rate or payout form named. The Spanish-language third-party piece claims Bitcoin cashback and a 10% USDC yield, which is not confirmed by Kontigo’s own pages and reads as promotional. The home page cites “over 10,000” user reviews, but the store rating on Google Play and the App Store is not stated. The app is available on both stores.

Disputes are covered in the terms, in a way that says more about Kontigo’s legal posture than about customer protection. The terms require good-faith negotiation for up to 15 business days after written notice, then say the matter goes to the courts of Delaware, with local consumer-protection authorities remaining available. Chargebacks are not mentioned, and the terms tell you to report unrecognised transactions as soon as possible. The longer the gap between an unfamiliar charge and your report, the harder any dispute becomes, regardless of the card network behind the card.

What this means in practice is that the everyday details of the card are the things you find out by using it. A reader who is comfortable with that — and with self-custody — can treat the card as a tool to spend USDC where it is accepted, and accept the limits of the documentation. A reader who needs a card that is documented from the merchant’s side (which networks, which tokenisation, which merchants it works with) is not given that information up front.

What can go wrong

Five risks are worth weighing before you put a meaningful USDC balance behind a Kontigo card.

The first is the gap in the public information. The card issuer, the BIN sponsor, the regulator, and the licensing chain are all unstated. Without them, you cannot easily check who is responsible if the programme ends or if a regulator acts, and you cannot check the BIN to see which network and country the card is issued in. Several merchants decline prepaid or foreign-issued card numbers, and a Kontigo card whose BIN is hard to identify is harder to predict at the till.

The second is self-custody. The Kontigo footer says users hold assets in their own custody, and the terms add that assets may sit in a self-custodied wallet or with third-party custodians, that Kontigo cannot access or recover private keys, and that the user is solely responsible for credentials. Two-factor authentication, card freeze, and insurance are not stated. If you lose your seed phrase, lose your device, or fall for a clipboard-hijacking piece of malware that swaps a copied address, the loss is yours, and blockchain transfers are generally final. A stolen private key has no built-in recovery.

The third is the conversion and FX path. Because the card spends from USDC and the local merchant settles in fiat, the conversion happens at the moment of payment through the rate and spread in the Kontigo app. Without a published margin, your effective cost depends on the rate you see in the app at the time. A second, smaller, often-overlooked cost is the network fee on Base, which is paid in ETH and which you must hold in the same wallet in order to top up.

The fourth is platform risk. A third-party report describes a hack that drained 340,905.28 USDC from 1,005 Kontigo user accounts, with the company stating that refunds were processed. The dates in that report are not verified, and the report is unofficial. A US$20M seed round was reported in December 2025 by a Latin American fintech outlet, again as a third-party claim. Both items are useful context, neither is a primary source, and the underlying risk — that any crypto platform, self-custody or not, sits in a wider ecosystem of bridges, custodians, and on-chain counterparties — is real. History shows that even large programmes get wound down: Visa ended its global agreements with FTX on 13 November 2022 and the FTX US debit card was wound down by its issuer, and WaveCrest was suspended by Visa in Europe in 2018, closing every WaveCrest-issued Visa programme.

The fifth is regulatory and tax risk. The Kontigo card is a USDC product, and USDC has briefly lost its peg before (in March 2023, during the US banking crisis), and TerraUSD collapsed in May 2022. Stablecoins are not necessarily stable. Where you live, the card may also be a taxable event each time you spend: in the US, the IRS treats digital assets as property, so spending USDC is a disposal measured at fair market value on the day, and a capital gain or loss if the holding is for investment. The terms do not give tax advice, and neither does this review.

What to take instead

Three alternatives are worth weighing against Kontigo, each with a different trade-off.

International Visa Card (score 6.7 / 10) is a US-issued Platinum Visa, virtual for now, with a physical card described as “coming soon”. It costs $5 to issue, has no maintenance fee, and runs in three plans: Classic (free), Pro ($9.00/month), and Max ($19.00/month). Spending in USD is free on every plan; foreign currency carries the Visa exchange rate plus a 2% FX fee. Funding is via USDC or USDT into the USD account at 1:1 with no fee, and the same account accepts USD, EUR, SEPA, SWIFT, and FedNow deposits. There is no cashback. The account is not available to residents or legal registrants of Belarus, mainland China, North Korea, Cuba, India, Iraq, Iran, Israel, Myanmar, Nepal, Nicaragua, Russia, Syria, Turkey, Ukraine, Venezuela, or Vietnam, and FATF grey-list countries are reviewed case by case. Purchases are blocked in North Korea, Cuba, Iran, Russia, Syria, Ukraine, and Venezuela. The rule is by residence or registration rather than citizenship. Compared with Kontigo, this is a card with a clear fee structure, a published country list, and an explicit FX margin — at the cost of being a prepaid Visa rather than a USDC-on-Base product.

UNi Card (score 6.1 / 10) is a multicurrency Mastercard that spends from the UNi.Global account balance, with no annual fee and no foreign transaction fee. Conversions happen at live OTC rates, and the marketing line is “no hidden exchange fees”. Spend-to-Earn rewards go up to 3% with the card. Country availability, the form factor, the issuance fee, and the top-up options are not stated in the public material. Compared with Kontigo, UNi Card is more clearly positioned as a multicurrency Mastercard, with a stated rewards ceiling and a fee structure, but it carries the same kind of information gap that Kontigo does around countries and top-ups.

Morse (score 7.5 / 10) runs a fully virtual Visa prepaid debit card that spends from the Morse Balance in any currency, with “zero foreign exchange fees or markups” on the real-time Visa rate. Paying online and contactless is free. Deposits are by debit card, stablecoin transfer, or Account Details in USD, EUR, MXN, COP (BRL needs a Brazilian CPF), and USDC, USDG, and EURC on Solana are free, while other tokens and blockchains carry a fee. The Morse Wallet is self-custodial, and Bitcoin, USDT, Ethereum, and other tokens can be deposited. Eligibility is by residence, not citizenship, with the app in over 140 countries for peer-to-peer use and local add/withdraw in over 70. Closed-beta countries (Australia, Japan, Singapore, Switzerland, the UK, and others) need an invite code, and the card itself is “available only in certain countries” with the list not published on the card page. The card-issuance and monthly fees are not stated on the card page, and Morse “cannot serve customers subject to sanctions issued by the United States” (also the UK, EU, and UN). Compared with Kontigo, Morse is a virtual Visa with a published “no FX markup” promise, a self-custody wallet, and explicit sanctions wording — at the cost of being card-only and virtual.

A short comparison:

If your priority is the clearest published fee structure, International Visa Card is the most legible of the three. If your priority is a self-custodial USDC experience with a no-markup FX line, Morse is the closest match to Kontigo’s idea, with a published “no FX markup” promise. If your priority is a multicurrency Mastercard with a stated rewards ceiling, UNi Card is the most direct comparison on the everyday-spending side.

Who I would recommend it to

I would recommend the Kontigo card to a narrow reader and only with eyes open. The reader I have in mind is in one of the countries named in Kontigo’s footer — Argentina, Bolivia, Brazil, Chile, Colombia, El Salvador, Mexico, or Peru — and already lives in USDC because their local currency does not hold value. They are comfortable with self-custody, with holding ETH on Base to pay the network fee, and with the idea that the issuer, the BIN sponsor, and the regulator are not named on the public site. They will use the card at merchants that accept the underlying card network without issue, and they will not rely on it for ATM cash, mobile wallet support, or dispute outcomes.

For everyone else, the answer is to look at the alternatives. A reader who wants published fees and a named country list will find International Visa Card easier to evaluate. A reader who wants a multicurrency Mastercard with a stated rewards ceiling and no foreign transaction fee will find UNi Card a closer everyday-spending fit. A reader who wants the closest analogue to Kontigo’s idea — a USDC balance spent through a real-time Visa rate, with no FX markup — will find Morse a more clearly documented option. None of the four is a bad choice in absolute terms, but the choice depends on which gaps you are willing to live with, and on which the public pages leave open.

Frequently asked questions

What is the Kontigo card?

Kontigo describes its card as the first international credit and debit card in USDC that earns yield, with the card spending directly from a US dollar stablecoin balance. The site also groups the product with hybrid, credit, and debit cards, but the public pages do not say which form factor, which network, or which issuer sits behind it.

How does the Kontigo card work?

The card debits purchases from your USDC balance, and the Kontigo app runs on Base, a low-fee Ethereum layer-2 network. You fund the balance by sending USDC on Base to the address shown in the app, paying the Base network fee in ETH. At the point of sale, the app converts USDC to the merchant’s currency at the rate and spread it shows at the time.

Is Kontigo a bank?

No. The Kontigo footer says the company does not provide financial services or take deposits, and the terms hold assets in user custody. Kontigo, Inc. is a Delaware corporation, but the card issuer, the banking or e-money partner, and the relevant licences are not named on the public site.

Who owns Kontigo?

Kontigo, Inc. is incorporated in Delaware. The site’s footer and terms describe a self-custody model where users hold their own assets, with the company stating it does not provide financial services or take deposits. A US$20M seed round was reported in December 2025 by a Latin American fintech outlet, but the report is third-party and unverified.

Where is the Kontigo card available?

The card is offered by country of residence, with sanctioned and high-risk jurisdictions excluded. The site footer lists Argentina, Bolivia, Brazil, Chile, Colombia, El Salvador, Spain, the United States, Mexico, and Peru under “Countries”, but those entries are not tied to card eligibility, and the supported residence list is set in the app rather than published on the marketing pages.

How do I top up the Kontigo card?

You top up by sending USDC on the Base network to the deposit address shown in the Kontigo app. The home page says topping up in USDC is commission-free, while you still pay the Base network fee in ETH from the same wallet. Top-up in USDT or in non-Base networks is not described on the public pages.

Is the Kontigo card free?

The home page advertises sending, receiving, topping up, and saving in USDC as “without commissions”, but the terms say card and conversion fees, commissions, and spreads are shown in the app and may change. Issuance, monthly, ATM, and FX fees are not stated on the public pages, so the only way to know what a specific transaction costs is to read the app screen before you confirm it.

Is the Kontigo card safe?

Safety has two sides. The self-custody side means you control the keys, but it also means you bear the risk of losing your seed phrase or sending to a wrong address; blockchain transfers are generally final. The platform side is harder to assess because the card issuer, the BIN sponsor, and the licences are not named, and a third-party report describes a hack that drained 340,905.28 USDC from 1,005 user accounts, with Kontigo stating that refunds were processed.

How do I add the Kontigo card to Apple Wallet or Google Pay?

The public site does not state whether the card supports Apple Pay or Google Pay, and the form factor and the network are not published. Whether tokenisation is available will be visible in the app and at the mobile wallet after the card is issued.

How do I delete my Kontigo account?

The terms describe a closure process that requires no pending obligations and either a zero balance or a withdrawal already instructed. They give a reasonable period, for example 30 days, to instruct a withdrawal of digital assets, and allow Kontigo to sell assets and hold the proceeds in a fiat currency it chooses if no instruction is given, without paying interest. The exact in-app steps are not described on the public site.
