Kast Card review: fees, cashback and USDT top-ups

Kast puts a stablecoin wallet and a payment card in one app. The interesting part is the exit: dollars out to a bank account over SWIFT, or a card you tap in a shop. As of February 22, 2026, the virtual card was listed at $2 and the physical card shipped for $40. Signing up takes a few minutes; the fee schedule is where I would slow down.

What the Kast Card is

Kast is a mobile app whose home screen reads "KAST - Global stablecoin banking". It holds stablecoins and issues a card that spends that balance. A stablecoin is a token built to hold a fixed value, usually one US dollar, which is what makes it usable for groceries: the balance does not swing while you decide what to buy.

Two formats are on offer. The virtual card lives in the app and works for online checkout, and for tap payments once you add it to Google Pay or Apple Wallet. The physical card arrives by post and works at an ATM as well as at a till.

Mr How pitched Kast at a specific problem in Pakistan: getting money out of crypto. He named two risks in peer-to-peer trading, where you sell USDT to a stranger and take a bank transfer. The counterparty can scam you, and a transfer the bank links to crypto can put the account itself at risk. Until crypto moves through official banking channels in Pakistan, he said, that problem stays. Kast, in his account, offers a card and a way to have a payment arrive in your bank account instead.

Incoming transfers can be made in USDC, USDT, USDe, PYUSD or RLUSD. For USDT the app listed eight networks, and that choice matters more than it looks.

A crypto card is not a bank account. You spend a balance you topped up in crypto, and the provider converts it to local currency when you pay or withdraw. The money sits with a provider, the card only works where that provider operates, and every purchase is a crypto transaction underneath.

Setting up and verifying an account

Verification comes first. No card can be ordered and no payment received until the account is verified, so treat the identity check as the first real step rather than an optional extra. Payment providers have to identify their customers, which is why the app asks for an ID and an address.

1. Download the app and tap Sign up, then choose Google, a mobile number or an email address.
2. Enter the one-time code that arrives, set a PIN and a password, and switch on the touch or face lock your phone already has.
3. Add your phone number and enter the second one-time code.
4. Tap Verification on the home screen and accept the terms.
5. Fill in your country, address, city, state and zip code, and give your occupation. The creator put "student" and it went through.
6. Photograph the front and the back of your ID card and submit both.
7. Submit proof of address. The creator used the same ID card, because the address printed on its back matched the address he had typed.

The address is the part I would be careful with. Whatever you type has to match the document you upload, and the name has to match your ID. When the two disagree, expect a rejection and a second attempt. Once the check clears, the card and the receiving features open up.

Moving USDT from Binance into Kast

The top-up path starts in Kast and finishes in Binance. The creator used Tron's TRC-20 network because its fees are low, a choice worth copying only if your exchange supports the same network.

1. Open Kast, tap Receive and choose the stablecoin you are sending.
2. Pick the network. The creator chose Tron (TRC-20) for lower fees.
3. Copy the wallet address the app shows.
4. Open Binance, tap Send, select USDT and select Tron (TRC-20).
5. Paste the address, enter the amount and confirm the transfer.

The network step is the one that can cost you money. A USDT address on Tron and a USDT address on Ethereum are different strings, and coins sent on the wrong chain may not arrive at all, or may need a recovery process the sender cannot do alone. Copy the address from the app rather than typing it, and check the first and last few characters after pasting. I would send a small amount first, confirm it lands, and only then move the rest.

The creator's point was that this replaces the peer-to-peer step. Instead of finding a buyer and waiting for a bank transfer, you send the stablecoin to an address inside Kast and spend from there. That takes the stranger out of the withdrawal. It does not take the record out: the coins still leave an exchange account with your identity on it, and the exchange keeps its own log.

Sending dollars to a bank account over SWIFT

Not everything has to be spent on the card. The app also pays out to a bank account in dollars over SWIFT, the messaging network banks use for cross-border transfers. The creator put the time at one to three business days, because the payment goes through the banking system rather than staying inside the app.

1. Tap Pay and choose USD via SWIFT.
2. Select your country (Pakistan in the example), then decide whether the money goes to your own account or someone else's.
3. Enter the amount, which the creator put at $200 in his demonstration.
4. Add the bank name, the full IBAN, the SWIFT code and the recipient's name. He suggested searching for the SWIFT code online.

Two things I would check before sending. What your bank charges to receive a foreign wire comes out of the amount that lands. And if the name and address on the receiving account do not match what the sending side expects, the payment can bounce back.

The creator said the transfer arrives as a foreign remittance, which he presented as a plus for the relationship with the bank. Your bank may still ask where the money came from. A payout that traces back to a crypto exchange is exactly the kind of transfer some banks question, and answering those questions is your job, not Kast's.

Ordering the virtual card and the physical card

Card ordering sits under Cards. The standard card is the first option and it is free. The virtual-only version was listed at $2, and a promo code the creator showed took it to $0; the price you see depends on whether an offer is running when you sign up. After applying, the card appears in the app, and Details shows the number and expiry you need at checkout.

The virtual card is the cheap way to start. It cannot be used at an ATM because there is no plastic, but it works online and can be added to Google Pay or Apple Wallet. For the physical card, choose the physical plus virtual option, set the name you want printed, and confirm the card fee, which came up as free. Shipping is $40 and has to be covered from your balance, so the account needs that much in it. You then enter your full address and phone number, and the card is posted to you.

The $40 is the number I would think hardest about. It is a shipping charge paid before you have used the card once. If the parcel is delayed, or the card does not suit you, that money is already gone, so ask support about the refund policy before you order.

Fees, limits and the 2% cashback

The virtual card is $2, waived with the code the creator showed. The physical card carries no card fee but $40 for global shipping. Spending earns 2% back on the free standard card, and the creator said that applies to ATM withdrawals, online purchases and tap payments in shops alike. The other cards on the list cost more and pay 5% or 8% on card spend. An Explore tab in the app also advertised offers of up to 5% yield and 4% extra cashback.

The rest of the fee schedule, the spending and ATM limits, and the conditions on the higher yield and cashback offers are not covered, so read Kast's own fee page and reward terms before you count on any of those figures.

Card programmes usually earn on currency conversion and on ATM use. If the card bills in dollars and you spend in rupees, there is a conversion somewhere in the chain, and the rate is set by the provider rather than by the market you see on a chart. ATM operators add their own charge on top, set by the machine, not by Kast. A 2% reward is small next to a conversion markup plus an ATM fee, so treat the reward as a discount on spending you were going to do anyway.

Rewards come with conditions too: a cap on how much spend earns the bonus, exclusions for certain merchants, and a clawback if you refund the purchase. The same logic applies to the higher yield and bonus-cashback offers on the Explore tab, which usually depend on holding a balance, locking tokens for a period or reaching a tier, and the headline rate can change. I would read the terms as if the top number were the best case, because it usually is.

Where the balance sits, and the tax question

Custody is the question I would answer before funding the card properly. A card that spends crypto needs the provider to hold the balance, or to convert it the moment you pay. Self-custody means you hold the private key, the string that controls a wallet; if the app holds that key for you, the balance is custodial in practice. Read the terms to see which model applies, and keep spending money there rather than savings. A custodial balance depends on the provider's safeguarding and on its ability to keep serving your country.

Then there is tax. In many countries, spending crypto through a card counts as a taxable sale, even when you are buying groceries. You compare the value of the coins when you pay with what you originally paid for them, and the difference is a gain or a loss to report. A card turns one withdrawal into dozens of small transactions, so the paperwork adds up quickly. Keep a record of each payment: date, coin, amount and value in local currency at the time.

A SWIFT payout may need declaring under local rules too, and those rules differ a lot between countries. Keep records from the first transaction rather than reconstructing them later, and ask a local accountant how crypto disposals are treated where you live.

The risks worth weighing

The problem the creator started with does not disappear. A card does not make a crypto-linked bank transfer invisible. If your bank asks about the source of a SWIFT payout, you still have to answer, and the answer involves an exchange account and a stablecoin balance.

A wrong-network send is the fastest way to lose money here. No support ticket reliably reverses a transfer made on the wrong chain, which is why the small test amount is worth the few minutes.

Stablecoins carry their own risk. The coin is a promise from an issuer, not a bank deposit, and the peg can slip if the issuer runs into trouble. Holding a balance in one is a choice you make every day you leave money in the app.

Terms can change under you. Kast's disclaimer notes that platform policies, fees, card approvals and banking integrations can change over time and vary by country, so a card that works today may not work next year, and the terms you agreed to are not the terms that will always apply. Regulatory uncertainty in Pakistan, which the creator raised, is part of the same picture.

There is also the plain risk of a fake app. Install from the official store listing, check the developer name, and never type your password or a wallet recovery phrase into a page you reached from a message or an ad.

What to check before you order

Start with the prices in the app, not the ones in this article. They were current in February 2026, and a card programme can reprice a virtual card or a shipping fee without much notice.

Ask support, in writing, about the monthly charge if there is one, the conversion markup when you spend in rupees, the ATM fee and the daily or monthly limits. Those four numbers decide whether the card is cheap or expensive, and they matter more than the 2%.

Confirm that your country is supported and which documents verification accepts, then send a small test transfer on the network you plan to use before moving a real amount. Ask your bank what it charges for an incoming SWIFT payment and whether it will query a transfer that comes from a crypto service.

Keep records for tax from day one, and check the cap on the reward before you treat the 2% as a reason to route spending through the card. If you are unsure, the virtual card is the low-cost way to test the whole thing, because the $40 shipping charge is the one cost you cannot get back easily.

The card solves a real problem: it turns a stablecoin balance into something you can spend without meeting a stranger. Whether it is cheaper than the alternatives comes down to numbers you have to ask Kast for, starting with the conversion markup on every rupee you spend.
