The KAST card turns a stablecoin balance into a Visa number you can tap, swipe or load into Apple Pay. There is no bank account, no IBAN to memorise, and for people who already hold USDT or USDC, it is one of the more direct ways to spend crypto at a real-world shop. The idea is straightforward, but the execution has rough edges that matter once you start using it: a country list nobody publishes upfront, a card programme whose issuer is not named, and a track record on Trustpilot that is hard to ignore. This review walks through who KAST actually works for, what it costs in practice, where the experience is smooth, and where you should be cautious.

Conditions are current as of October 28, 2026.

Verdict

KAST earns 6.1 out of 10 in this review. That score reflects a card that does several things well — stablecoin top-up at zero per cent, a generous rewards structure, and a Visa number that works wherever Visa works — but a card programme that is unusually opaque about who actually issues the card and what regulators oversee it. For a stablecoin holder who already lives in a country KAST supports, the day-to-day experience is solid. For anyone who needs certainty about who holds their money, or who lives somewhere KAST may not cover, the same card looks far less convincing.

The breakdown by criterion:

Who the card suits: stablecoin holders who want to spend a USD balance in shops, online and at Visa ATMs, who are comfortable with crypto-native workflows, and who can stomach some ambiguity about who the issuer is. Who it does not suit: anyone who needs a fully licensed, fully transparent card programme, anyone in a country that may or may not be supported, and anyone who plans to use the card for gambling-adjacent or other restricted merchant categories.

Will they give you the card

The short answer is: you will not know until you try. KAST does not publish a list of supported countries. Instead, the app shows a country-of-residence selector during sign-up, and only after that step do you find out whether KYC is open to you. The terms describe a separate “Restricted Locations” list, but the public pages do not name which countries are on it. If your country is not listed, KAST says bluntly that “KAST is not available there” and you cannot complete the application.

There is a citizenship twist worth understanding. KAST distinguishes between where you live and what ID you hold. Someone living in a supported country but holding a passport from a restricted region can still fail KYC. Dual citizens who hold an ID from a supported country can pass. Only the account holder’s own ID is accepted, and the terms warn that a VPN does not bypass country rules. You can technically create an account in an unsupported country, but the app stays locked at Level 1 and the cards never arrive.

The honest reading: eligibility is narrower than the marketing implies, and you cannot check it before downloading the app. For anyone whose country is unclear, that is a real friction point. If your home country is on a typical “crypto-friendly” list and you hold a matching passport, you will most likely be fine. If you live in a jurisdiction with strict crypto rules, or you hold a passport from one, expect to be turned away at KYC rather than at the sign-up screen.

How to get it

KAST uses a three-level verification structure, and what the card can do depends on which level you reach.

Level 1 is account creation. You give a phone number, receive an OTP, set a PIN, enter an email and select your country of residence. At this level you can use the app but cannot send or receive funds, and you cannot order a card.

Level 2 unlocks the card. You submit a government-issued ID — passport, national ID card or driver’s licence, all of which must be valid — plus a selfie and a liveness check. Once Level 2 clears, you can fund the account and order a virtual or physical card.

Level 3 is reserved for the heavier use cases. It requires proof of address, may ask for proof of funds, requests your citizenship, and unlocks USD and EUR accounts and global payouts. US residents are asked for an SSN. The minimum age is the legal age in your country, which is typically 18.

The order of steps is the same in every case: install the app, complete KYC, then order a card. KYC processing time is not stated on the public pages, nor are the specific reasons a Level 2 application might be rejected — the only rejection reasons mentioned explicitly are an expired ID or a country that is not supported. The two rejection reasons are coarse, which means the actual outcome is often “wait and provide more documents.”

Cards come in three flavours. The Standard tier issues a Visa Platinum. Premium issues a Visa Infinite metal card. Private issues a gold-plated Visa Infinite. There are also three collectible designs — Pengu, Solana and Bitcoin — and every account can hold up to ten cards in total. The balance itself sits in USD, with stablecoin deposits converted 1:1 to that USD balance at zero spread.

Physical card delivery is quoted at seven to ten business days. The Standard tier pays 40 USD for shipping. The list of countries the physical card is shipped to is not stated on the public pages, and the cost to replace a lost or damaged card is not stated either.

What it really costs (Fees)

Cost is where KAST looks competitive on first glance, but a few figures deserve a closer look.

The annual fee structure is a hard one to compare. Standard is genuinely free, but the 1,000 USD Premium and 10,000 USD Private fees are charged annually upfront with no monthly option. These are not casual upgrades — they target users who spend heavily enough for the cashback and Reserve rewards to outweigh the membership.

The 0.5% to 1.75% FX range is also worth weighing. The fee depends on three variables at once: your country of residence, the country where the transaction takes place and which card programme you hold. That makes the actual rate a moving target. A user in a low-fee residence country paying in euros may see 0.5%, while a user elsewhere paying in another non-USD currency may see 1.75%. The terms do not pin the figure to a single, simple rate, which means you cannot predict the cost of a given purchase without testing it.

The most surprising cost is the 0.50 USD declined-transaction fee. If your balance is too low when the card is run, you are charged half a dollar for the attempt. Combine that with the user reports on Trustpilot describing repeated declined-transaction fees pushing balances negative, and this becomes a cost worth understanding before you rely on the card for everyday use. Merchants can also place pre-authorisation holds, so a payment that later settles for less than the initial hold can briefly eat into your available balance.

A few worked examples put the fees in context.

Buying a 50 USD coffee in a non-USD country: the FX fee at 0.5% adds 0.25 USD; the transaction fee is 0%; total cost 50.25 USD. At 1.75% the same coffee incurs an additional 0.875 USD.

A 30 USD online subscription paid in USD: no FX fee, no transaction fee, total 30.00 USD. The card is at its cheapest when you spend dollars on dollar-priced merchants.

A 200 USD ATM withdrawal abroad: 3 USD flat + 2% (4 USD) = 7 USD, plus an FX fee on the 200 USD of 1 USD to 3.50 USD. The total cost lands between 9 and 10.50 USD for the cash, before your home bank adds anything on top of a foreign-ATM receipt.

Renewal and reactivation fees exist but the amounts are not stated on the public pages. That is worth asking customer support about if you are weighing the long-term cost of the card.

How to top it up (Top up)

Funding the card is the smoothest part of the experience. KAST accepts four stablecoins — USDT, USDC, PYUSD and RLUSD — and the first two are supported on five networks each: Ethereum, Solana, Polygon, Arbitrum and TRON. The app lists the currently active networks inside the top-up flow, and the fee is zero per cent. The blockchain’s own network fee (gas on Ethereum, bandwidth and energy on TRON) is charged by the chain itself, not by KAST.

This breadth of network support is unusual. Most crypto cards accept a token on one or two networks and leave you to bridge the rest. With KAST, an Ethereum user and a Solana user can each send their preferred token to the same card without converting first, and a Polygon or Arbitrum user is not locked out either.

Bank deposits are also possible, though less prominent in the app. US dollars can come in via ACH (2 USD), FedWire (15 USD) or SWIFT (30 USD). Euros can come in via SEPA (0.5%). The minimum top-up amount is not stated on the public pages.

There is one inconsistency worth flagging. The terms say the acceptable tokens are “currently USDT and USDC”, while the marketing material and app explicitly support PYUSD and RLUSD as well. The terms lag behind the product, which is normal for fast-moving crypto products but also means you should verify in the app before sending a less common stablecoin.

Spending is from your own balance, deducted at the moment of purchase. There is no credit line and no overdraw. If the balance is empty, the transaction is declined and the 0.50 USD fee applies. If a non-stablecoin token is sent, it may be auto-converted at a fee shown in the app before it lands as USD.

Stablecoin withdrawals (moving USDT or USDC back out to a wallet you control) are also possible. The fees depend on the network. On Solana, sending USDT or USDC costs 1 USD plus 0.1%. On Arbitrum, USDC costs 0.20 USD plus 0.1%. On Ethereum, USDT or USDC costs 6 USD plus 0.1%. On TRON, USDT costs 5 USD plus 0.1%. The minimum withdrawal is 5 USD. The balance treatment on account closure is not stated.

Paying with it every day

The day-to-day experience is what KAST does best. The card is accepted wherever Visa is taken — the marketing claims 150 million merchants across 170-plus countries, which is consistent with Visa’s own footprint. From the merchant’s point of view the card looks like any other Visa prepaid product; they see the BIN, the authorisation result and the settled amount, and that is the end of their involvement.

Virtual and physical cards both work with Apple Pay and Google Pay at zero per cent. Samsung Pay support is not stated. Adding the card to a phone wallet takes a few seconds, and the tokenised Device Account Number means the actual card number is never shared with the merchant or stored on Apple’s or Google’s servers. The card issuer can restrict a tokenised number on a card-by-card basis if needed, for example blocking it for online use while keeping it active in person.

Cashback is paid in USD the moment the transaction is authorised. Standard returns 1.5% on the first 2,000 USD of spend per month. Premium returns 2% on the first 10,000 USD. Private returns 3% on the first 40,000 USD. Premium and Private also earn KAST Points on eligible spend, on top of the USD cashback. SOL staking rewards in Points are 0.25 per 1 SOL every two days for Standard and 0.5 for Premium and Private. The “Reserve” balance rewards programme (8% on Standard, 10% on Premium, 12% on Private) is currently scheduled to end on 1 July 2027, after which those figures are likely to change.

Premium and Private cards also unlock the Visa Infinite benefits bundle, which includes travel insurance, purchase protection, lounge access and an eSIM. These benefits have to be registered through the Visa Benefits portal before they activate, which is a step some users miss until they need the cover.

The Terms prohibit a familiar list: weapons, controlled substances, Ponzi or pyramid schemes, counterfeit goods, Darknet and Tor purchases, adult content and pseudo-pharmaceuticals. Gambling MCC 7995 is not mentioned, so the card’s treatment of gambling transactions depends on the card programme’s policy rather than the terms. That uncertainty is worth keeping in mind if gambling is part of your spend.

The iOS app, listed as “KAST: Global USD Account” by developer Troia Limited, sits at 3.97 from 276 ratings as of 8 October 2026. The Google Play rating was not read for this review.

If you need to dispute a transaction, the terms say to contact KAST within 90 days. The company’s liability is capped at USD 500 per dispute, and the chargeback process itself is not described. That cap is well below what a bank-issued Visa or Mastercard would typically offer, and it is a serious limitation for any purchase that might go wrong.

What can go wrong

The risk profile is the part of the review worth sitting with. Several pieces of information are missing from KAST’s public pages, and the user reports that do exist describe a specific set of problems.

KAST describes itself as “a financial technology company, not a bank.” Cards, custody and the on-ramp and off-ramp are “provided by licensed partners.” The terms name the operating entity as KAST Tech, registered number 16223, incorporated in Anjouan in the Comoros. Governing law is Seychelles, and disputes go to SIAC arbitration in Singapore. The App Store developer is listed as Troia Limited. The card issuer and BIN sponsor are not named, and the public pages refer only to “one of our Partner.” Named partners in the terms include Tazapay and BitGo. The homepage carries logos for Stripe, Privy, Fireblocks, Visa, Sardine and Elliptic. No licence numbers appear on any of the pages read for this review.

This is a meaningfully less transparent setup than most major crypto cards. A typical European crypto card discloses an e-money institution licence and a regulator. KAST does not. Availability of the card is described as “subject to regulatory approval,” and no regulatory action was found in search results, but the absence of named licences is itself a data point.

Trustpilot scores sit at about 2.5 on regional pages and 2.7 on the main page, from roughly 170 reviews read on 20 October 2026. The themes in negative reviews are consistent. Users report frozen or restricted accounts shortly after depositing, with funds placed on hold. Several describe the 0.50 USD declined-transaction fee stacking up against an empty balance and pushing the balance into the negative. ATM withdrawals that did not dispense cash but still debited the account appear more than once. Users making transfers between their own accounts report repeated document requests each time. KAST replies to most negative reviews with a consistent message: accounts can be restricted by security and compliance systems, and users should contact support. The pattern is reminiscent of the kind of compliance-driven friction that other regulated crypto platforms describe, but the lack of a named regulator means there is no obvious external body to escalate to.

On the security side, the public pages do not state whether 2FA is supported in the app, whether instant card freeze is available, or whether card insurance is offered beyond the Visa Infinite benefits that come with Premium and Private. Users can set lower spend limits in the app, which is a useful safety valve, but the absence of a clear feature list is unusual for a payment product.

Support runs through the KAST Concierge help center, available 24/7 at every tier, with a VIP Concierge for Private members. The support email appears in company replies as [email protected]. The membership page itself offers English only, with no Russian-language option at the time of reading.

To put this in context: crypto custody has a long history of failure. Mt. Gox lost around US$350 million between 2011 and 2014, Coincheck lost about US$400 million in 2018 and the Ronin Network lost US$625 million in 2022. These are not the same as a card programme restricting an account, but they show how unforgiving the space can be when something goes wrong. Stablecoins themselves are not risk-free: Tether’s USDT and Circle’s USDC together hold about 90% of stablecoin market capitalisation, but both have depegged at points, and a stablecoin depeg during a card transaction would create a settlement problem the user has no way to resolve. USDT and USDC transfers are also not censorship-proof — Tether has frozen tokens in OFAC-sanctioned wallets.

A few practical risk-mitigations follow from the facts above. Send a small test top-up before committing larger balances. Avoid leaving more on the card than you can afford to have restricted for a compliance review. Read the Visa Infinite benefit terms before assuming you are covered. Keep the receipt of every transaction, because the dispute window is 90 days and the company’s liability cap is USD 500.

What to take instead

No single alternative is a perfect substitute, and the best fit depends on what you want the card to do.

MetaMask Card is the strongest comparison in the self-custody space. It is a Mastercard with a virtual card issued instantly, and a Metal tier that can be pre-ordered in the app. Funds stay in the connected wallet until the moment of payment, which removes the custodial top-up step. The catch is geography: sign-up is open in around 45 listed countries and territories, with the rest on a waitlist, and US and UK sign-ups are temporarily closed per the FAQ. Cashback is 1% on Virtual and up to 3% on Metal (3% applies to the first 10,000 USD spent, then 1%), paid in mUSD. The Metal tier costs 199 USD a year. The card is issued by Monovate and the card provider is Crypto Life. Proof of residency is required at sign-up, and citizenship rules are not stated.

TokenPocket’s TP Card runs on Arbitrum and offers a Visa debit card in selected European countries and territories (Germany, France, Spain, Switzerland and others) and a Mastercard debit card in Australia, Canada, Hong Kong, Japan, Taiwan, New Zealand, Singapore, South Korea and the UK. The Americas rollout is planned for Q2 2025. Balances are in EUR24 and USD24. The headline detail is a 1% fee on crypto deposits, which is refunded later via rewards or reduced transaction fees — an unusual flow worth considering before signing up. The card is virtual only.

Zeal sits on Gnosis Pay infrastructure, with virtual Visa cards addable to Apple Pay and balances in EUR, USD and GBP. The card is currently live in the EU, UK, Brazil, Colombia, Mexico, Japan, Singapore, the Philippines, Indonesia and Thailand, with further rollouts mentioned in update notes for Mexico, Colombia and Bolivia. Zeal charges no additional FX fee and converts at the Visa wholesale rate, though the underlying Gnosis Pay fees (such as ATM fees) may still apply. Up to 4% cashback is paid in GNO on Gnosis Chain, and the rate is conditional on holding GNO in the card Safe. No fee schedule is published on zeal.app or the App Store listing, which is itself a consideration. The app also advertises up to 5% variable APY on EUR and USD balances.

A few broader points from the category background are worth carrying into any comparison. The card issuer and BIN sponsor matter: Visa and Mastercard themselves do not issue cards to consumers, they license issuers, and they can suspend a programme. Visa’s suspension of WaveCrest in 2018 closed every WaveCrest-issued Visa programme in Europe. Visa also terminated its global agreements with FTX in November 2022, with the FTX US debit card wound down by its issuer. Both cases illustrate that even a Visa-branded card can disappear, and the user is dependent on the issuer remaining in good standing. In the EU, MiCA’s transitional period runs until 1 July 2026 for providers already operating under national law, after which a MiCA authorisation is required. EMIs safeguard customer funds, but those funds are not bank deposits and are not covered by deposit guarantee schemes.

Who I would recommend it to

If you already hold USDT or USDC, you live in a country KAST clearly supports, you can verify that in the app without making a deposit, and you treat the card as a spending tool rather than a savings account, KAST does the basics well. The top-up experience is best-in-class for stablecoin breadth, the USD spend fee is genuinely zero, and the rewards structure is generous for heavier users.

If any of the following applies, look elsewhere. You need a clearly named card issuer and a regulator you can look up. You live in a country whose KAST eligibility is not obvious. You plan to keep a large balance on the card for an extended period. You rely on chargebacks for high-value purchases, given the USD 500 liability cap. You need Samsung Pay support. You want a card you can keep using for years without surprises around renewals, reactivation fees or programme changes — the fact that those amounts are not stated is itself a warning.

The honest summary: KAST is a useful tool for a specific kind of user in a specific kind of situation. Outside that envelope, the trade-offs become harder to defend.

Frequently asked questions

What is the KAST card?

The KAST card is a Visa debit card issued through the KAST app. Your balance is held in USD, and you top it up by sending USDT, USDC, PYUSD or RLUSD from a crypto wallet. The card then spends that balance wherever Visa is accepted, online, in store and at Visa ATMs.

How does the KAST card work?

You install the app, complete KYC, then send stablecoins to a deposit address. The deposit is converted to USD at a 1:1 rate with zero spread. When you tap or swipe the card, the USD balance is debited, with the FX fee applying only for non-USD transactions.

Is KAST a bank?

No. KAST describes itself as a financial technology company, not a bank. Cards, custody and the on-ramp and off-ramp are provided through licensed partners, and the operating entity named in the terms is KAST Tech in Anjouan, Comoros. No banking or e-money licence numbers are stated on the public pages.

Who owns KAST?

KAST does not publish ownership information on the pages read for this review. The App Store developer is listed as Troia Limited. The terms name KAST Tech (registration number 16223) as the contracting entity, incorporated in Anjouan, with governing law in Seychelles and arbitration at SIAC in Singapore.

Is the KAST card available in my country?

KAST does not publish a country list. Eligibility is shown at the country-of-residence step of sign-up. If your country is not listed, KAST says the card is not available there. Citizenship matters too: holding a passport from a restricted region can disqualify you even if you live in a supported country.

How do I get a KAST card?

Download the iOS or Android app, complete Level 1 (phone, email, country), then Level 2 (government ID plus selfie and liveness check) to unlock card ordering. Order a virtual card for instant use or a physical card for delivery in seven to ten business days.

Does the KAST card require KYC?

Yes. Level 1 is account creation only. Level 2 (ID plus selfie) is required to order a card and send or receive funds. Level 3 (proof of address, citizenship, source of funds) is required for USD and EUR accounts and global payouts, with US residents asked for an SSN.

How do I top up the KAST card?

Open the top-up screen in the app, select a token and network, and send from your own wallet. USDT and USDC are supported on Ethereum, Solana, Polygon, Arbitrum and TRON. PYUSD and RLUSD are also supported. The fee is zero per cent; you pay the blockchain’s own network fee only.

Is the KAST card safe?

The card uses standard tokenised Visa infrastructure and a balance model that cannot overdraw. The main concerns are around the operating entity: no card issuer or regulator is named on the public pages, the entity is in Anjouan, and Trustpilot reviews describe frozen funds and repeated document requests. Treat the card as a spending tool, not a place to park a balance.

Is the KAST card worth it?

For stablecoin-heavy users in clearly supported countries who treat it as a spending tool, the zero per cent top-up and USD spending are hard to beat. For users who need a transparent issuer, a high chargeback ceiling or a clearly licensed programme, the answer depends on how comfortable you are with the trade-offs.
