KAST Card review 2026: fees, cashback, countries and who it fits

Yes, for some people. KAST is a custodial Visa card that spends USDC and USDT with no funding fee, and its free Standard tier pays 1.5% cashback. It suits stablecoin holders in Latin America and other supported countries who spend often. Residents of Russia cannot use it, and the paid tiers are hard to justify on cashback alone.

POOL BTC is an independent comparison site for bitcoin mining pools and the tools around them. We are not KAST, we do not issue cards, and this is not financial advice. The figures below come from KAST's membership page, homepage, blog and help pages, checked on 2026-10-04. Where KAST's own pages disagree, we show both versions. Where they say nothing, we say so.

What is the KAST Card?

The KAST Card is a Visa card attached to a stablecoin app where you store, earn, move and spend digital dollars. You fund it with USDC or USDT and pay at ordinary merchants. KAST Tech says it is not a bank, and the account is custodial: licensed partners hold the funds, not you.

KAST names Fireblocks and BitGo as custody partners on its homepage. An independent review site names Rain as the card issuer, which we did not see confirmed on KAST's own pages. KAST claims acceptance at more than 150 million merchants in more than 170 countries. Apple Pay and Google Pay work, depending on the region.

There are three membership tiers. Standard is free and comes with a Visa Platinum card. Premium costs $1,000 a year and Private costs $10,000 a year, and both come with Visa Infinite cards. A KAST blog post from March 5, 2026 also mentions a Limited Founders card sold for a single payment of $5,000.

How much does KAST cost, and what are the limits?

Standard costs nothing a year. Its first two virtual cards are free, each extra one costs $2, and a physical card costs $40 for shipping. Adding USDC or USDT is free. Spending in currencies other than USD costs 0.5% to 1.75%, and every ATM withdrawal costs $3 plus 2%.

"Not stated" here means not stated on the official site (checked 2026-10-04). The next table lists fees that KAST's blog and help pages describe for the account without splitting them by tier.

USDe, PYUSD and RLUSD are also accepted on selected networks. We found no published daily spending limit. The ATM line is where costs bite: taking out the maximum $250 costs $3 plus $5, so $8, about 3.2% of the cash you get.

Why do KAST's cashback figures differ between pages?

KAST publishes two versions. The membership page shows 1.5%, 2% and 3% cashback by tier, plus points on the paid tiers. A KAST blog post from March 5, 2026 lists 1%, 3% and 5% as points rewards for Standard, Premium and Private. We follow the membership page, since it is the tier page, and you should check the app before paying.

The difference matters most for the paid tiers. On cashback alone, Premium's extra 0.5% over Standard returns $250 if you hit the $50,000 cap, a quarter of the $1,000 fee. Private's extra 1.5% returns $3,000 at the $200,000 cap, against a $10,000 fee.

The rest of the case for paying rests on two things. KAST points are one, and their cash value is not stated on the official site (checked 2026-10-04). The higher rate on your held balance is the other, and it is a promotion that ends on July 1, 2027, not a guarantee. Standard earns no KAST points at all.

Who is KAST for, and who should skip it?

KAST fits people who already hold USDC or USDT, live in a supported country and want to spend through an ordinary Visa card without paying to fund it. It fits less well if you need cash often, want to keep your own keys, or live in Russia, where KAST does not accept customers.

The clearest match is someone in Argentina, Brazil, Chile, Colombia, Mexico or Peru, the six countries KAST names on its Argentina page, who keeps savings in stablecoins and pays for daily things by card. Standard gives 1.5% back with no annual fee.

If you mine bitcoin, keep in mind that the card runs on stablecoins. Funding with another asset may trigger the 2% to 5% automatic conversion, so switching to USDC or USDT first is usually cheaper. You can estimate what a rig earns with our mining calculator.

Skip KAST if you want self custody, because your balance sits with KAST's partners. Frequent ATM users pay $3 plus 2% each time. People who spend mostly in a currency other than USD lose 0.5% to 1.75% on each purchase.

Which countries can use KAST?

KAST publishes no full country list. Eligibility is decided during identity checks in the app. Russia is excluded, as are Ukraine, Iran, China and several other countries. Argentina and other Latin American countries are supported. For other CIS countries, KAST states nothing publicly, so check in the app before you rely on the card.

The excluded list, per KAST's terms as quoted by an independent review site, covers Russia, Ukraine, North Korea, Myanmar, Iran, Syria, Cuba, South Sudan, Yemen, China and Afghanistan. KAST's own concierge help page, updated on August 9, 2026, says eligibility is checked through KYC in the app rather than a public whitelist.

Two details trip people up. Using a VPN to get around location checks is prohibited by KAST's terms. And an ID document from a restricted country can fail verification even if you live in a supported one, so a Russian passport holder living in Argentina may still be refused.

Verification has three levels. Level 1 asks for name, email and phone. Level 2 adds a government ID and a liveness check, and you need it for cards. Advanced banking verification with proof of address opens USD accounts and higher limits.

Is KAST safe, and who holds your money?

KAST is custodial. Fireblocks and BitGo hold the assets, so you depend on KAST and its partners rather than on your own keys. We found no confirmed breach of KAST itself. Account protection includes MFA, biometrics, device verification, fraud monitoring and a card freeze inside the app.

On August 28, 2026 a card issuing partner had an incident that affected Avici cards. KAST said its own cards were not affected, according to a card news site that covered the event. Card programs in this market share infrastructure, so trouble at one partner can reach several brands.

Custody also shapes what happens when something goes wrong. Crypto transfers are irreversible, so a payment sent to the wrong address cannot be pulled back. Card disputes are possible but cost $30 each and must be raised within 90 days. Accounts can be frozen for compliance reviews, and your balance stays out of reach while that runs.

How do you start with KAST?

Install the app, pass two levels of verification, add USDC or USDT, and a virtual card is issued right away. A physical card is ordered separately in the app and arrives in 10 to 20 days. The steps below are the ones KAST describes on its own pages, nothing more.

1. Install the KAST app. You can use our referral link to KAST.
2. Sign up and complete Level 1: name, email and phone number.
3. Complete Level 2: a government ID and a liveness check. Cards require this level.
4. Fund the account with USDC or USDT. Both are free to add.
5. Get your virtual card, issued instantly, and add it to Apple Pay or Google Pay if your region supports them.
6. For a physical card, open Cards, choose a tier, tap Order, enter your address and pay the $40 shipping fee if you are on Standard. Delivery takes 10 to 20 days.

What are the risks?

The main risks are custody and rules that can change. Your money sits with KAST's partners, eligibility is not public and can change without notice, and accounts can be frozen for compliance checks. Costs pile up at ATMs and abroad, and paid memberships are billed upfront for a full year.

The rate on held balances is a promotion with an end date, July 1, 2027, and KAST does not guarantee it. The cashback conflict between the membership page and the blog means the rewards you see in one place may not match what you get. A $1,000 or $10,000 membership is paid in advance, so changing your mind later is expensive.

Fees are the quieter risk. Automatic conversion of assets other than stablecoins costs 2% to 5%, foreign exchange adds up to 1.75%, and an ATM withdrawal costs about 3.2% at the $250 maximum. None of this is a view on any coin's price. It is simply what the card costs to use.

How does KAST compare with RedotPay, Tria and ether.fi?

KAST and RedotPay are custodial Visa cards, while Tria and ether.fi Cash are self custody. KAST has free funding and free virtual cards. RedotPay charges more for cards and funding. Tria has no FX fee but pays rewards in its own token with vesting. KAST, RedotPay and Tria all exclude Russia.

The figures for RedotPay, Tria and ether.fi come from independent card comparison sites, and they may lag behind each issuer's own pages. Those sites also publish scores; treat the scores as opinions, not measurements. For more issuers side by side, see our crypto card comparison. For a self custody card whose ordering is currently paused, see our Ready card review.

If KAST covers your country and you spend mostly in USD, Standard costs nothing to try. You can open a KAST account here and decide on a paid tier later, once you know your real monthly spend.
