The KAST card promises something quietly radical: spend stablecoins like ordinary money, at zero conversion cost, from your phone or a physical Visa. On paper, the fee structure is genuinely attractive. Underneath it, though, sits an offshore corporate structure with no named issuer, no published country list, and a thin stream of user complaints about frozen funds. This review unpacks both halves — what KAST does well, and where it could leave you stuck.

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

Verdict: 6.1 out of 10 — attractive fees, unresolved structural risk

KAST scores 6.1 out of 10. That middle number is not a shrug; it is the sum of a card that does the mechanics of daily spending unusually well and a company structure that leaves too many questions open.

If you already hold stablecoins, spend mostly in US dollars, and travel widely, KAST is one of the more straightforward crypto cards on fees. A Standard membership costs nothing, converting a stablecoin deposit to your dollar balance is 0%, and spending that balance in USD is 0%. You can hold virtual and physical cards, add them to Apple Pay or Google Pay, and pay anywhere Visa is accepted. For that profile — stablecoin holders spending USD balances across many networks — the everyday experience is genuinely good.

What holds it back is everything behind the card. The issuer is never named. No licence numbers appear on the pages I could read. The contracting entity is registered in Anjouan, Comoros, with governing law in Seychelles and arbitration in Singapore. There is no published list of supported countries — you only find out at KYC, and if your ID is from a restricted region you can be refused even when you live somewhere supported. And on Trustpilot, users report frozen accounts, repeated declined-transaction fees, and document requests that loop without resolution.

So: strong on cost and convenience, weak on transparency and track record. Whether that trade is acceptable depends almost entirely on how much of your money you would be willing to see sit behind a freeze, and how much you need the card to simply work, everywhere, without questions.

Here is how the score breaks down.

Will They Give You the Card?

The short answer is: it depends on where you live and what passport you hold — and KAST will not tell you in advance. Eligibility is decided at KYC, not at download.

The country list is residence-based and shown only when you reach the verification step. The app says plainly: if your country is not listed, KAST is not available there. But the list itself is not published, so you cannot check eligibility from a website before committing to an application. A Restricted Locations list is referenced without any countries actually named.

Citizenship matters separately from residence, and this is the part that catches people out. KAST states that if you currently live in a supported country but hold an ID only from a restricted region, you may still be ineligible to pass KYC. In other words, your address does not save you if your document does not qualify. Dual citizens holding an ID from a supported country may pass. Only the account holder’s own ID is accepted, and a VPN does not bypass the checks.

There is one loophole-shaped edge case worth knowing: you can create an account while physically in an unsupported country, but KYC remains locked until you are in a supported one. The app opens; the card does not follow.

So before you download anything, the honest test is: where do you live, and is your passport or national ID from that same place? If either answer is unclear, you are signing up to find out the hard way.

How to Get It

Getting a KAST card means climbing through three verification levels, and the level you reach determines what the card can actually do.

Level 1 is account creation: phone number with a one-time code, a PIN, email, and country of residence. This gives you app access only — no sending or receiving funds, no cards.

Level 2 requires a government ID (passport, national ID card, or driver’s licence, and it must be valid) plus a selfie with liveness check. This is the level that unlocks sending and receiving funds and ordering cards.

Level 3 asks for proof of address and enhanced checks, with citizenship requested. This unlocks USD and EUR accounts and global payouts. You may also be asked for source-of-funds documents, which means showing where your money came from. US residents are asked for an SSN. Minimum age is the legal age in your country, 18 in most.

The practical sequence is simple: download the app, complete KYC, then order a virtual or physical card. Processing times are not stated, and neither are official rejection reasons beyond the obvious ones — an expired ID is refused, and so is an unsupported or restricted country.

Fees: What It Really Costs

Here is where KAST is strongest and where the surprise lives. The headline fees are excellent; the small print fees are where a balance can quietly bleed.

• Annual membership: Standard 0 USD, Premium 1,000 USD/year, Private 10,000 USD/year — billed annually upfront with no monthly option.
• Physical card: Standard is 0 USD card fee plus 40 USD delivery; Premium and Private include the physical card.
• Extra virtual card: 2 USD (in some regions 2 USD also applies to the included Standard virtual cards).
• Inactivity: 1 USD/month after 12 months.
• Renewal and reactivation fees exist, but the amounts are not stated.
• Stablecoin top-up: 0%. Card spend in USD: 0%. Transaction fee: 0%. Apple Pay and Google Pay: 0%.
• Non-USD foreign exchange: 0.5%–1.75%, depending on your residence country, the country of the transaction, and the card programme.
• Non-USD transactions under 25 USD: 0.10 USD.
• Declined transaction (insufficient balance): 0.50 USD.
• ATM: 3 USD flat plus 2% of the amount, plus the FX fee if not in USD.
• Non-stablecoin tokens may be auto-converted at a fee shown in the app.

The full table, so you can see it at a glance:

Let me run three everyday payments through it, because the headline 0% is not the whole story.

Coffee in New York, 8 USD, paid in USD. You spend from your dollar balance. The spend fee is 0%, the transaction fee is 0%. If you tap it through Apple Pay, still 0%. This is the case KAST is built for, and it costs you nothing beyond whatever you already paid to acquire the stablecoins.

A hotel in Tokyo, 40,000 JPY, paid in a non-USD currency. This is where the FX fee bites. The conversion runs through Visa at the wholesale rate plus the 0.5%–1.75% FX fee, which varies by your residence country, the transaction country, and your card programme. The amount is above 25 USD, so the 0.10 USD small-transaction surcharge does not apply. You should budget roughly one to two percent on top of the converted price.

A declined online payment at 12 USD on a non-USD merchant. Two fees can land here. If the merchant authorises in a non-USD currency under 25 USD, you pay 0.10 USD. And if the payment fails for insufficient balance, you are charged 0.50 USD. That declined fee is the one to watch — user complaints in 2026 describe it stacking repeatedly and pushing a balance negative, which is exactly the failure mode that turns a free card into an expensive one.

The tiers change more than the fee schedule. Standard gives Visa Platinum, two free cards, 1.5% cashback and 8% Reserve. Premium (1,000 USD/year) upgrades to Visa Infinite metal with shipping included, 2% cashback, 10% Reserve and +1% Points. Private (10,000 USD/year) is gold-plated Visa Infinite, 3% cashback, 12% Reserve, +2% Points and a VIP Concierge. The Reserve rewards programme on balances ends 1 July 2027. SOL staking earns Points at 0.25 per SOL roughly every two days on Standard and 0.5 on Premium and Private. Visa Infinite benefits (travel, purchase protection, lounge, eSIM) need registering on the Visa Benefits portal.

How to Top Up

Topping up KAST starts with sending a stablecoin to the right network, and the fee for doing so is 0%. The choice is which stablecoin and which chain.

• USDT and USDC, on Ethereum, Solana, Polygon, Arbitrum, and TRON (the app lists the current networks).
• PYUSD and RLUSD also accepted.
• No bank account needed.
• The Terms say acceptable tokens are “currently USDT and USDC,” which conflicts with the PYUSD and RLUSD listed in the app — a small inconsistency worth noting.

The 0% top-up fee has two asterisks. Network fees are excluded, so the blockchain itself still charges you to send. And sending on a network the provider does not support can mean lost funds, because blockchain transfers are irreversible.

Bank deposits are available too, at a price: USD ACH 2 USD, FedWire 15 USD, SWIFT 30 USD, and EUR SEPA 0.5%. The minimum top-up is not stated.

Spending is from your own balance, with each purchase deducted immediately — this is not credit. So your KAST balance cannot go negative through spending; the only route to a negative balance is the declined-transaction fee path described above.

If you want to withdraw back out, stablecoin withdrawal fees are: Solana (USDT, USDC) 1 USD + 0.1%; Arbitrum (USDC) 0.20 USD + 0.1%; Ethereum (USDT, USDC) 6 USD + 0.1%; Tron (USDT) 5 USD + 0.1%. Minimum 5 USD. The balance on account closure is not stated.

Paying With It Every Day

Everyday use is KAST’s strongest suit, and this is where it earns its 9 out of 10.

You get both virtual and physical cards, up to 10 cards per user. The standard tier is Visa Platinum; Premium and Private move up to Visa Infinite in metal and gold-plated finishes. There are also themed designs — Pengu, Solana, and Bitcoin. Your balance is held in USD, with stablecoin deposits converted 1:1 at a 0% spread.

Adding the card to Apple Pay and Google Pay is 0%, on both virtual and physical cards. Samsung Pay is not stated. You can pay wherever Visa is accepted — the service claims 150M+ merchants across 170+ countries. At ATMs, the card works across the Visa network, subject to the limits noted above.

Rewards are real but modest and tiered:

• Cashback in USD: Standard 1.5% on the first 2,000 USD/month; Premium 2% on the first 10,000 USD/month; Private 3% on the first 40,000 USD/month. Cashback is paid in USD when a transaction is authorised.
• KAST Points: Standard none, Premium +1% and Private +2% of eligible spend.

Two everyday frictions to expect. First, some merchants place a pre-authorisation hold, and a declined authorisation can leave a hold on your funds for several days — typically up to 7. Second, the Terms prohibit a long list of purchases: weapons, controlled substances, Ponzi/pyramid/MLM schemes, counterfeit goods, Darknet/Tor purchases, adult content, and pseudo-pharmaceuticals. Gambling (MCC 7995) is not mentioned either way.

The iOS app, “KAST: Global USD Account” by Troia Limited, sits at a 3.97 App Store rating from 276 ratings and was updated 2026-10-08. The Google Play rating was not read. If you have a dispute, the Terms say contact KAST within 90 days of the transaction, and the Company’s liability is capped at 500 USD; the chargeback process itself is not stated.

What Can Go Wrong

This is the section I would read twice before applying, because the risks are not about fees — they are about access and about who you actually entrust with the money.

The company is an offshore shell with a named-but-unlicensed structure. KAST describes itself as “a financial technology company, not a bank,” with cards, custody, and on/off-ramp “provided by licensed partners.” The Terms entity is “KAST Tech” (Reg No. 16223), incorporated in Anjouan, Comoros; governing law is Seychelles; arbitration is SIAC in Singapore. The App Store developer is Troia Limited. The actual card issuer and BIN sponsor are not named — only “one of our Partner.” Partners named in the terms include Tazapay and BitGo; homepage logos include Stripe, Privy, Fireblocks, Visa, Sardine, and Elliptic. On the pages I read, no licence numbers were shown and no regulator was named; availability is “subject to regulatory approval.” I found no regulatory action in search results, but absence of action is not the same as a licence.

Frozen accounts are the single most-reported problem. On Trustpilot — about 2.5 on regional pages, 2.7 on the main page, roughly 170 reviews as of 2026-10-20 — the dominant theme is accounts frozen or restricted soon after deposit, with deposits placed on hold. KAST replies to most negative reviews saying accounts can be restricted by security and compliance systems, which is a fair answer but does not get your funds back. Other themes: repeated 0.50 USD declined-transaction fees pushing a balance negative (April 2026), failed ATM cash dispensation with the amount still debited, repeated document requests on self-transfers, and slow support. The positive reviews praise the low fees and stablecoin spending, so the fees really are the thing people like; the friction is on the compliance side.

Security features are thin on the pages. The app lets you set lower spend limits, and custody is positioned as handled by licensed partners. But two-factor authentication, card freeze, and insurance are not stated on the pages I read — the Visa Infinite benefits apply only to Premium and Private. You can freeze a card in-app as a practical matter, but the security tooling is not spelled out.

Withdrawal and closure are incomplete. Balance on account closure is not stated, renewal and reactivation fees exist with unstated amounts, and withdrawal minimums and per-chain fees mean getting money back is not free, especially on Ethereum (6 USD + 0.1%). Programmes like this can also be wound down; Visa terminated FTX’s global agreements in November 2022, and a 2026 closure reported by a secondary source ended new loads on 8 July 2026 and spending on 8 August 2026 (single source, unconfirmed).

Where you are, matters. Because eligibility is residence- and citizenship-based and the list is hidden, there is a real chance you complete a KYC only to be refused. And because the issuer country can differ from your billing address, merchants may apply extra scrutiny — a card issued in one country can look “foreign” to a shop in another, and prepaid or foreign BINs are sometimes declined outright.

I want to be straight about the balance here: none of this is a prediction that your account will freeze. It is a description of what has been reported, and of the fact that the pages give you no licence number to check and no country list to check before you apply. Those two gaps are what separate KAST from cards issued by institutions you can name and verify.

What to Take Instead

If the fee structure is what draws you, KAST is not the only card with cheap stablecoin spending — and some alternatives are more transparent about who issues them. Here is how the main ones compare, drawing on their published scores and terms.

A few notes on each, so the comparison is fair:

• MetaMask scores highest of the four at 7.1. Sign-up is open in 45 listed countries and territories (Andorra, Argentina, Brazil, Canada, Mexico, Germany, France, Spain, Uruguay among them); other regions join a waitlist, and US/UK sign-ups are temporarily closed per the FAQ. It is a Mastercard, virtual card issued instantly, Metal pre-orderable after approval, one card per user. The catch is the Metal card is 199 USD/year, and it spends directly from a connected wallet on Linea, Base, Monad, and Solana.
• Rizon at 6.7 is aimed at people who “live in and are domiciled” in the US or LATAM countries, though the page also claims 122+ countries supported. It offers virtual, physical, and metal (coming soon) Visa Platinum cards, a free account tier, and 2.5% cashback redeemable from a cashback balance. Many prices are pushed to “check the app.”
• Zeal matches KAST’s 6.1. It is a Visa card with a virtual card for online use, addable to Apple Pay, and accounts in EUR, USD, and GBP. It charges no additional FX fee and converts at the Visa wholesale rate. Its cashback is paid in GNO and requires holding GNO in the card Safe to qualify. It publishes no fee schedule.

The pattern: KAST and Rizon lean toward the low-cost, stablecoin-first experience with the most generous fee headline; MetaMask leans toward wallet integration and has the clearest country sign-up list of the four; Zeal leans toward multi-currency and no added FX fee. None of these fixes the underlying question of issuer transparency — you should apply the same scrutiny to whichever card you pick.

Who I Would Recommend It To

I would recommend KAST to you if all of the following are true. You already hold stablecoins — mostly USDT or USDC — and want to spend a USD balance day to day without conversion drag. You live in a country where KAST’s KYC will accept you, and your ID is from a supported country, not just your address. You travel and want a Visa that works widely, including at ATMs, and you can live with an FX fee of up to about 1.75% on non-USD purchases. You are comfortable that a frozen account is a real possibility, and you would keep only a spending balance here, not your savings.

I would steer you away if any of these apply. You need a card you can rely on absolutely, with a named issuer, a published country list, and a support line that resolves problems. You are in a region where eligibility is uncertain or your document may be from a restricted country. You plan to hold a large balance long-term — the custody and freeze risk is the same whether you hold 200 USD or 2,000, but your exposure is not. Or you need features the pages do not promise: published insurance, a clear chargeback process, or stated two-factor authentication.

The blunt version: KAST is a good card for spending, held by a company you cannot fully verify. That is a fine trade if the amount at risk is money you can lose and re-acquire. It is a poor trade if it is the only card you have, or if a freeze would strand you.

Frequently asked questions

What is the KAST card?

The KAST card is a Visa payment card that spends from a stablecoin-backed USD balance rather than from a bank account. You load it with stablecoins such as USDT, USDC, PYUSD, or RLUSD, they convert to dollars at a 0% spread, and each purchase is deducted immediately. It comes as a virtual card, a physical card, or both, and works with Apple Pay and Google Pay. KAST describes itself as a financial technology company, not a bank.

How does the KAST card work day to day?

You add funds by sending a stablecoin to a supported network or by bank transfer, then spend that balance wherever Visa is accepted. Spending in USD costs 0% with no transaction fee, and adding the card to a mobile wallet is also 0%. Paying in a non-USD currency adds an FX fee of 0.5%–1.75%. Cashback of 1.5% to 3% returns in USD when a transaction is authorised, depending on your tier.

Is KAST a bank, and who owns it?

No. KAST states it is “a financial technology company, not a bank,” with cards, custody, and on/off-ramp “provided by licensed partners.” The contracting entity in the Terms is KAST Tech (Reg No. 16223), incorporated in Anjouan, Comoros, with governing law in Seychelles and arbitration in Singapore. The App Store developer is Troia Limited. The actual card issuer is not named, and no licence numbers appear on the pages I read.

Who can apply, and is KAST available in my country?

Eligibility is residence-based and decided at KYC, because the supported-country list is not published on the website. You can create an account in an unsupported country, but KYC stays locked until you are in a supported one. Citizenship matters too: if you live in a supported country but hold an ID only from a restricted region, you may still be ineligible. Only your own ID is accepted, and a VPN does not bypass this.

Does the KAST card require KYC, and what documents do I need?

Yes, in three levels. Level 1 is account creation (phone, PIN, email, country) and gives app access only. Level 2 needs a valid government ID — passport, national ID, or driver’s licence — plus a selfie, and unlocks funds and cards. Level 3 adds proof of address and enhanced checks (citizenship requested), unlocking USD/EUR accounts and payouts. You may also be asked for source-of-funds documents; US residents give an SSN. Minimum age is the legal age in your country.

Is the KAST card free, and what are the real fees?

The Standard tier is 0 USD a year, and there is no fee to open the account. A Standard physical card is 0 USD plus 40 USD delivery, an extra virtual card is 2 USD, and there is a 1 USD/month inactivity fee after 12 months. Spending in USD and topping up in stablecoins are both 0%. The costs to watch are the 0.5%–1.75% FX fee, 3 USD + 2% at ATMs, 0.10 USD on non-USD transactions under 25 USD, and a 0.50 USD fee on a declined transaction for insufficient balance.

How do I top up the KAST card, and which networks work?

You top up by sending a stablecoin to a supported network — USDT and USDC work on Ethereum, Solana, Polygon, Arbitrum, and TRON — and the top-up fee is 0%, though blockchain network fees still apply. PYUSD and RLUSD are also accepted, though the Terms only name USDT and USDC as acceptable. No bank account is needed. Bank deposits are possible too: USD ACH 2 USD, FedWire 15 USD, SWIFT 30 USD, and EUR SEPA 0.5%. The minimum top-up is not stated.

Where can I use the KAST card, and can I add it to Apple Wallet?

You can use it wherever Visa is accepted — the service claims 150M+ merchants in 170+ countries — and at Visa-network ATMs, subject to daily and per-withdrawal limits. You can add both the virtual and physical cards to Apple Pay and Google Pay at 0% fee. Samsung Pay is not stated. Note that merchants may apply extra scrutiny because the issuer country can differ from your billing address, and a few may decline a prepaid or foreign card outright.

Is the KAST card safe, and can my account get frozen?

KAST is not insured in the way a bank deposit is, and its custody and card partners are not clearly named. The real reports are on Trustpilot (around 2.5–2.7, roughly 170 reviews), where users describe accounts frozen soon after deposit, repeated declined-transaction fees, failed ATM cash dispensation, and repeated document requests. KAST says accounts can be restricted by security and compliance systems. There is no published insurance, and two-factor authentication is not stated on the pages I read.

How do I withdraw money from KAST, and what happens if I close my account?

You withdraw back to a stablecoin, with fees that vary by network: Solana 1 USD + 0.1%, Arbitrum 0.20 USD + 0.1%, Ethereum 6 USD + 0.1%, and Tron 5 USD + 0.1%. The minimum withdrawal is 5 USD. USD and EUR bank payouts require reaching Level 3. One gap to note: what happens to a remaining balance if you close your account is not stated, and renewal or reactivation fees exist with unstated amounts — so check this before you ever let a meaningful balance sit here.
