If you have ever lost a card because a card programme shut down overnight, or you simply do not want a third party holding the keys to your Bitcoin, the Oppi card is the kind of product that catches your eye. It is a Mastercard debit experience that sits on top of a self-custody crypto wallet, with the keys staying on your own device. That alone is unusual: most crypto cards today are custodial, with the brand holding the balance on your behalf.

The trade-off shows up in the price. Oppi charges an activation fee on the virtual card, asks you to pay for a physical card if you want the plastic, and layers a 2%-2.5% foreign exchange markup on anything you buy in a currency other than US dollars. The wallet itself, by contrast, is free, and there is no monthly subscription. So Oppi is built for people who already hold crypto, want to keep custody, and would rather pay a small fee for the privilege than hand over their seed phrase to a custodian.

In the verdict below I score it at 7.2 out of 10 and walk through the eligibility rules, sign-up steps, the real costs, the top-up options, what everyday use looks like, and the risks you should weigh before you apply. I also compare it with three alternatives and answer the questions readers ask most often. I have not used the card myself; everything below comes from Oppi’s own pages, the App Store listing, and a comparison with the figures I have flagged as unofficial wherever they differ from the company.

Conditions are current as of October 28, 2026.

Verdict: 7.2 out of 10

The score reflects where Oppi does well and where it stumbles. The card claims availability in 210+ countries, the wallet supports a sensible spread of coins and networks, and the self-custody design is a real point in its favour. It loses points on cost (the FX markup and the upfront fees) and on the thinness of the published information about the issuer, the licence, and the dispute process.

Here is how the score breaks down.

The audience that gets the most out of Oppi is self-custody users who want the option of a piece of plastic or a mobile wallet without giving up their keys. If you are looking for a cashback-heavy everyday card, or you want a clearly identified European e-money issuer behind the programme, you will probably do better with one of the alternatives I look at later.

Who they will give the card to

Oppi is unusually broad in its reach. The company says the card is available in “210+ countries”, and an independent review site, which I am treating as unofficial, lists 221. That is a wider footprint than most crypto cards manage, because the wallet itself does not require KYC — you only have to identify yourself when you enable the card. If you are happy to use the wallet to hold crypto, you can do that almost anywhere; the card features are what trip the identity check.

A handful of countries are off the table. Oppi’s restricted-country list sits inside its FAQ, and although I could not read the answers cleanly, the same independent source names Cuba, Iran, North Korea and Syria, and points out that the company’s AML policy also bars Crimea, Donetsk and Luhansk. The phrase “210+ countries” is sometimes explained on third-party pages as a reference to Mastercard’s acceptance footprint rather than the card’s own availability, which is worth keeping in mind.

Eligibility is checked at sign-up, so there is no point trying to game it. The card is offered “subject to regulatory limits”, which is a polite way of saying that the final say belongs to the issuer, not to Oppi. If you are in a supported country and your documents pass the verification, you should be able to get the card. If you are not, the wallet will still work for storage and on-chain transfers, you just will not have a card number to spend from.

What that means for you: if you are an adult, you can hold crypto in Oppi from almost anywhere. To turn that balance into a card, expect to hand over a government ID and a selfie, and to wait for Oppi to confirm your country and identity. If your country is sanctioned, the card is closed to you regardless of where you actually live.

How to get it

Sign-up is designed to be quick. The wallet side of Oppi is the part you create first, and you can do that without uploading any documents. To enable the card features, KYC kicks in: a government ID plus a selfie. I could not find confirmation of the age requirement on Oppi’s own pages; if you are unsure whether you meet the threshold, treat that as something to confirm with the company directly. Proof of address is not stated on Oppi’s pages either, although one third-party site says it is required under the AML policy.

There is no published set of KYC tiers. Oppi describes one level: a government ID plus selfie is what enables card features. Higher limits, if they exist, are not advertised, and the independent source that mentions source-of-wealth questionnaires and video calls above certain daily or monthly amounts is not Oppi’s own material, so treat that as unofficial.

Once you are verified, the virtual Mastercard is the default product. The official site says you can have multiple virtual cards on the same balance, and the physical card is optional. One quirk worth noting: Oppi’s own comparison table lists the physical card as Visa, while the App Store listing for the wallet says the virtual card is Mastercard and the physical card is Visa, and an independent page says the company offers both Visa and Mastercard. The currency is US dollars, with the FX markup that I cover below applying to anything else.

Physical card delivery time, the countries it ships to, and the cost of a replacement are not stated. The headline price of $100 includes shipping, but the fine print is thin.

What that means for you: start with the wallet, complete KYC when you are ready to spend, and choose the virtual card first. Only order the physical once you know the card works for the way you actually pay, and only if the $100 price makes sense for the convenience you will use.

Fees: what the card really costs

The honest answer to “what does Oppi cost?” needs a bit of unpacking, because the company is not as transparent as the bigger crypto cards.

The headline figures from Oppi’s own pages are these. Virtual card activation is a one-time $10, of which $5 is credited back to your balance, so the net cost is $5 (a comparison table on the same site says the issuance fee is $5, which lines up with that). The physical card is $100 including shipping, paid once. There is no monthly or annual fee, and no inactivity fee mentioned. ATM withdrawals are supported but the fee and the allowance are not stated on the card’s own pages.

The foreign exchange markup is where the day-to-day cost lives. Oppi charges 2% to 2.5% on purchases that are not in US dollars. Crypto top-ups are converted at a real-time rate, and the page describes swap fees as “low” without quantifying them. The App Store listing, in an apparent conflict with the rest of Oppi’s site, says travel bookings have “no currency exchange fees” — that is not consistent with the FX charge, so I would not rely on it without testing it.

A few everyday scenarios make the cost concrete. If you spend €200 on a hotel in Paris and your card balance is in USD, the FX markup alone is €4 to €5 before the merchant’s own currency conversion. If you top up with $500 of USDT and spend it on a US website in dollars, you are paying the network fee for sending the USDT and the conversion spread inside Oppi, but no FX markup. If you take €100 out of an ATM in Berlin, the FX markup is on top of whatever the ATM operator charges, plus an Oppi ATM fee that the company has not published.

One last wrinkle. An independent source says card loading is “typically 1%-2%” and that the virtual card is free in some app stores. Both claims contradict Oppi’s own published fees, so I would not plan around them. The card’s own prices are the ones that will actually show up on your statement.

What that means for you: budget for a $5 effective activation fee and a 2%-2.5% FX charge every time you spend in a non-dollar currency. If you pay mostly in USD, the FX charge does not bite; if you travel a lot, it adds up. Do not rely on the App Store line about zero currency exchange fees until you have tested it on a small purchase.

Top up: how to fund the card

Top-ups are the part Oppi does well. The wallet supports BTC, BCH, BNB, ETH, LTC, SOL, USDT, TRX and USDC, and the supported chains are Ethereum, BSC, Polygon, TRON and Solana. The App Store listing talks about “40+ assets”, which is broader than the nine names on the main page — a third-party source flags that as a discrepancy. The pre-funded model is the one in use here: you deposit crypto, it sits in your wallet, and the card spends from that same balance. The virtual and the physical card share the same balance, so you do not have to load each card separately.

Conversion happens at a real-time rate, with a swap fee that the company describes as “low” without giving a number. Fiat top-up is not described, which is consistent with the self-custody design — there is no bank account to pull from inside Oppi. Minimum top-up amounts and per-transaction card-loading fees are not stated on Oppi’s own pages; the independent figure of “1%-2% for card loading” is not itemised anywhere I can verify, so treat it as a guide, not a promise.

Because the networks supported are a mix of expensive and cheap, the chain you choose to send on matters as much as the coin. USDT on TRON is usually cheap to send, USDC on Polygon is usually cheap to send, and ETH mainnet can be expensive during busy periods. ERC-20 USDT can only be sent if you have a little ETH in the wallet to pay gas; sending USDT to a TRON address from an Ethereum wallet will simply lose the funds, because the addresses are not interchangeable. USDC on TRON is not a native option either — Circle stopped supporting USDC on TRON in 2024 — so if a guide tells you to send USDC via TRC-20, that advice is out of date.

What that means for you: pick the right network before you send. TRON and Polygon are the cheapest for stablecoins, Solana is usually cheap too, and Ethereum mainnet is fine if you are sending a larger amount and the gas does not eat into it. Always send a small test transaction first if you are using a new address or a new chain. And remember that blockchain transfers are irreversible, so a typo or a wrong network is your problem, not Oppi’s.

Paying with it every day

In the real world, Oppi behaves like a fairly ordinary Mastercard debit card, with the usual provisos about prepaid products. The virtual card is the default; the physical card is optional and costs $100. Apple Pay and Google Pay are supported, which means you can add the card to your phone and pay at the contactless terminal without taking the plastic out of your wallet. ATM withdrawals are supported — the main site says you can “withdraw cash worldwide” — but the fee and the monthly allowance are not stated.

Spending rules and blocked merchant categories are not spelled out on Oppi’s pages. Many issuers block gambling transactions (the MCC 7995 category) as a matter of policy, but whether Oppi does so is something I could not confirm from the published material. If a specific category matters to you — gambling, crypto purchases, adult content, subscriptions — that is a question to put to support before you commit to the $100 physical card.

The rewards scheme is called Oppi Points: every eligible card purchase earns points that you can redeem as top-ups. The earn rate and any caps are not published, so I cannot tell you whether this is closer to a generous 2% or a token 0.5%. If you are choosing between Oppi and a card with a clear cashback percentage, the unknown earn rate is a real gap.

The app is iPhone-first. The App Store listing says it needs iOS 15.6 or later, and the listing also names M-series Macs and Apple Vision. The Google Play listing exists, but I did not read the Android side directly; an independent page quotes a 4.3 to 4.8 score depending on where you look, and the App Store rating is 4.6 out of 5 from 50 ratings as of 20 October 2026. The listing is in English only. In-app support tickets are listed in recent release notes.

Online payments are subject to the same 3-D Secure flow as any other Mastercard. That can mean a one-time code or a biometric prompt on first use, and it can also mean a decline if the merchant’s address verification system cannot match your billing address to the issuer’s records — address verification is mainly a US, Canada and UK thing, and a card issued elsewhere can look “foreign” to a merchant in those countries, which is one of the structural reasons crypto cards get declined at unfamiliar online stores. Tokenised mobile-wallet payments through Apple Pay or Google Pay tend to be approved more often than raw card-number payments online, which is one practical reason to add the card to your phone.

What that means for you: pay with the phone when you can, keep the virtual card for online use, and treat the physical card as a backup. If you regularly buy from overseas websites, expect an occasional decline and a 3-D Secure prompt; that is the category, not Oppi specifically. If you want a published cashback rate, Oppi will not give you one.

What can go wrong

This is the section I would read most carefully if I were you. The Oppi card is not a bad product, but the published information around it is thinner than I would like.

The first thing to know is that the company behind the wallet is Encoin Limited, the developer named in the App Store listing. The site says the product is operated by Oppiwallet and is “VASP-certified”, which is a virtual asset service provider registration rather than a banking licence. The card’s issuer and BIN sponsor — the bank or e-money institution that actually issues the Mastercard — is not named in the public material I read. That matters because the issuer is the entity that ultimately handles your money, runs the compliance checks and processes disputes. With a Visa or Mastercard debit card, there is always a licensed institution somewhere in the chain; Oppi is just not telling you which one.

The self-custody model cuts the other way. Oppi’s site is explicit: your private keys stay on your device, and “Oppi does not hold your funds at any point”. That is reassuring in one sense — there is no Mt. Gox, no Coincheck, no Ronin-style custodian hack waiting for you here — but it also means you bear full responsibility for your seed phrase, for phishing, and for clipboard malware that swaps copied addresses. Crypto transfers are irreversible; a stolen private key has no recovery path.

The complaint picture is small but thin. A search across Trustpilot and Reddit turned up no complaints about Oppi itself; one independent source says Trustpilot has a single review, and that one reviewer reported a physical card that was never delivered — a single anecdote, not a pattern. The App Store rating of 4.6 from 50 ratings, with all four visible 2025 reviews positive, is the only meaningful user signal I have, and 50 ratings is not a large sample. The absence of complaints can mean a product is solid, or it can mean a product is too new to have built up a track record; here, both are true.

Other things to know: card freeze, spending controls and insurance are not described in the published material. The dispute process is not described either — the support centre lists FAQ questions without answers, so I cannot tell you what happens if a charge is wrong or a merchant does not deliver. Support runs through the in-app ticket system and a generic email address; hours and languages beyond English are not stated. The rewards scheme, Oppi Points, is new enough that the rate has not been published.

One category-level risk worth flagging: the crypto card industry has seen programmes 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. In 2018, Visa suspended WaveCrest in Europe and every WaveCrest-issued Visa programme closed. MiCA — the EU’s markets-in-crypto-assets regulation — has a transitional period that runs until 1 July 2026 for providers already operating under national law, so the European side of this market is in a state of change right now. Oppi’s claim of “210+ countries” and the lack of a named issuer means the regulatory path the card sits on is not obvious from the public material, and that is a real consideration if your balance is non-trivial.

What that means for you: do not load more onto the card than you can afford to keep in something you might not be able to access for a few weeks. Treat the seed phrase with the seriousness the self-custody model demands — anyone who has the words can drain the wallet. If you ever need to dispute a charge, do not assume you have the same rights as a bank customer; the prepaid card protections are not the same as a regulated bank account’s. And if a specific category of spending matters to you (gambling, for example), ask support before you put the physical card in your wallet.

What to take instead

If Oppi does not fit, three alternatives are worth a look. None of them is a perfect swap, because Oppi’s combination of broad country coverage and self-custody is unusual, but each solves a specific problem the others do not.

A few words on each.

TokenPocket’s TP Card is a Mastercard/Visa debit that runs on the Arbitrum network, with balances in EUR24 and USD24. It is best for people who already use TokenPocket as their main wallet, because the card lives inside the same environment. The fee structure is unusual: there is an NFT creation fee partly covered by TokenPocket, and a 1% deposit fee that is later refunded through rewards. The country list is shorter than Oppi’s — parts of Europe and a handful of Asia-Pacific jurisdictions, with the Americas planned for later — so it is a smaller footprint by design.

MetaMask Card is the closest direct competitor. It is also a self-custody card in the sense that it spends directly from a connected wallet, with the private keys staying on the user’s side. The virtual card is free; the Metal card costs $199 a year; the cashback is paid in mUSD into a Money Account. The headline 3% on Metal falls to 1% after the first $10,000 of spend, which is a real cap. Sign-up is open in around 45 listed countries, with other regions on a waitlist, and the US and UK are temporarily closed. Proof of residency is required. The issuer is Monovate and the card provider is Crypto Life, both of which are named on MetaMask’s pages, and that transparency is a point in MetaMask’s favour.

KAST is the heavy-hitter on cashback. Standard is $0 a year with 1.5% on the first $2,000 of monthly spend; Premium is $1,000 a year with 2% on the first $10,000; Private is $10,000 a year with 3% on the first $40,000. Stablecoin top-up is 0%, USD spending is 0%, and the non-USD FX fee is 0.5% to 1.75% depending on residence and card programme. The trade-off is the annual fee, which only makes sense at the higher spending tiers. Country availability is residence-based and shown at KYC, with a separate list of restricted locations that is referenced but not publicly named.

If your priority is keeping custody of your own keys, Oppi and MetaMask Card are the two to compare head-to-head. MetaMask Card is the more transparent of the two on issuer and fees, and the country list is smaller and more clearly drawn. Oppi is the one to pick if the country you are in is not on MetaMask’s list, or if you specifically want the multi-coin, multi-chain wallet experience that comes with the Oppi app. If you do not care about self-custody and you want the highest cashback, KAST is the option, on the assumption that your spending justifies the annual fee.

What that means for you: do not pick on score alone. Pick on the criterion that matters most to you — country coverage, self-custody, cashback, or annual fee — and check that the card you choose is actually available where you live.

Who I would recommend it to

After walking through the eligibility, the sign-up, the costs, the top-ups, the daily use and the risks, here is who I think should seriously consider Oppi and who should look elsewhere.

I would recommend Oppi to you if you already self-custody crypto and you want a way to spend that balance in the real world without giving up your seed phrase. The card supports a useful spread of coins and networks, the wallet is free to use, and the absence of a monthly fee means the card costs you nothing when you are not using it. If you are in a country that is not on MetaMask Card’s list, or you would rather not have a $199 annual Metal fee, Oppi’s $100 physical card is a reasonable middle ground. If your everyday spending is in US dollars, the 2%-2.5% FX markup does not apply, and the only ongoing cost is the network fee for the crypto you send in.

I would not recommend Oppi to you if you are looking for a clearly identified bank or e-money institution behind the card programme, because Oppi does not name one. I would not recommend it if you want a published cashback rate, because Oppi Points has no published earn rate or cap. I would not recommend it if you mostly spend in euros, pounds or another non-dollar currency, because the 2%-2.5% FX markup will add up. And I would not recommend it if you are not comfortable being your own custodian — if the idea of holding a seed phrase makes you nervous, a custodial card with a transparent issuer and clear chargeback rights will suit you better.

The honest summary is this: Oppi is a competent self-custody card at a price that reflects what it is, with gaps in transparency that you should know about before you put real money through it. Treat the $100 physical card as a paid convenience, not as a must-have, and keep the bulk of your long-term holdings in cold storage where the card cannot reach them.

Frequently asked questions

What is the Oppi card?

The Oppi card is a Mastercard debit experience that sits on top of the Oppi self-custody crypto wallet. You deposit crypto, it converts at a real-time rate, and the card spends from that balance in fiat at the point of sale. The wallet itself does not require KYC; the card features do.

How does the Oppi card work?

You fund the Oppi wallet with a supported coin on a supported chain, the balance is available to a virtual Mastercard (and an optional physical card), and you can add the card to Apple Pay or Google Pay for contactless spending. Non-USD purchases carry a 2%-2.5% FX markup, and ATM withdrawals are supported but the fee is not published.

Is Oppi a bank?

No. Oppi is operated by Encoin Limited, the developer named in the App Store listing, and the site says the product is VASP-certified, which is a virtual asset service provider registration. The card’s issuing bank or e-money institution is not named in the public material I read, so the licensed entity behind the card programme is not visible from the outside.

Who owns Oppi?

The App Store developer is Encoin Limited. The site describes the product as operated by Oppiwallet. There is no parent company, no licence number and no regulator named in the public material I read, so ownership beyond the developer name is not stated on Oppi’s own pages.

Is the Oppi card available in my country?

Oppi claims the card is available in “210+ countries”. An independent source lists 221 and names Cuba, Iran, North Korea and Syria as restricted, with the AML policy also barring Crimea, Donetsk and Luhansk. Eligibility is checked at sign-up, so the only way to know for sure is to start the application.

How do I get the Oppi card?

Download the Oppi wallet, create an account (no documents required for the wallet), then complete KYC with a government ID and a selfie to enable the card. The virtual Mastercard is the default; the physical card costs $100 including shipping and is optional.

Does the Oppi card require KYC?

Yes, to enable the card. The wallet itself works without KYC, but card features require a government ID plus a selfie. Higher limits, if they exist, are not advertised on Oppi’s own pages.

How do I top up the Oppi card?

Send one of the supported coins — BTC, BCH, BNB, ETH, LTC, SOL, USDT, TRX or USDC — to your Oppi wallet on a supported chain (Ethereum, BSC, Polygon, TRON or Solana). The card and the wallet share one balance, and the crypto is converted to fiat at a real-time rate at the point of sale.

Can I add the Oppi card to Apple Wallet?

Yes. Apple Pay is supported, as is Google Pay. Add the card from within the app, complete the issuer’s verification, and the tokenised version of the card will live in your phone’s Secure Element for contactless payments.

Is the Oppi card safe?

Safer than a custodial card in one specific way: the private keys stay on your device, so a custodian hack cannot drain your balance. Riskier in another way: you bear full responsibility for your seed phrase, and a stolen seed phrase has no recovery. Card freeze, insurance and the dispute process are not described in the published material, so the safety net beyond self-custody is thinner than a regulated bank’s.
