Kast Card

Verdict

The KAST Card is a Visa card built for spending stablecoins directly, with cashback paid in spendable US dollars rather than tokens. It fits global and remote earners who hold USDT or USDC and want to pay with no fee on US-dollar purchases. It is a custodial product, so it is a poor fit if holding your own keys matters to you.

The top line: it is free to start on the Standard tier, cashback of 1.5% that only reaches 3% on the Private tier at $10,000 a year, and your money held by a third-party custodian on KAST’s behalf. KAST’s homepage advertises “up to 5% cashback no matter where you spend”, but its own tier tables cap US-dollar cashback at 3%.

The rewards, and the catch

KAST’s cashback looks generous until you read the tiers. Every rate is gated by an annual membership and a monthly qualifying-spend cap:

• 3%, but only on Private. The 3% rate requires the Private membership at $10,000/year, and applies only to your first $40,000 of spend each month.
• 1.5% on the free tier. The Standard tier costs $0 and pays 1.5%, capped at your first $2,000 of monthly spend.
• 2% in the middle. Premium costs $1,000/year and pays 2%, capped at your first $10,000 of monthly spend.
• Paid tiers add KAST Points. Premium earns +1% and Private +2% in KAST Points on spend, a separate loyalty unit from the USD cashback.

Cashback is paid in US dollars you can spend, and appears the moment a transaction is authorized. Treat the marketed “up to 5%” with caution: KAST’s own tables cap US-dollar cashback at 3%, and the 5% figure is not substantiated by them.

Fees

There is no annual fee on the base Standard tier; it is $0. The higher “fees” are really memberships: Premium at $1,000/year and Private at $10,000/year buy higher cashback and higher caps.

• Zero on the everyday stuff. US-dollar card spend, top-ups, and Apple Pay and Google Pay are all charged at 0%.
• Foreign spend is the catch. Non-US-dollar spend carries a foreign-exchange fee of 0.5% to 1.75%, depending on your country of residence and where you pay. There is no monthly FX-free allowance and no tier waiver.
• Cards. Your first two virtual cards are free ($2 each after that, and in some countries the first costs $2); a physical card is free with a $40 shipping fee. You may hold up to 10 cards in total, and a renewal fee may be charged per the terms.

Custody and who holds your money

This is where KAST asks for real trust. The card is custodial. Under KAST’s terms, the virtual assets you deposit are “sold to KAST” and then held by a third-party partner custodian on KAST’s behalf, explicitly not for the users. KAST names Fireblocks and BitGo among its custody and security partners.

You fund the card with stablecoins, USDT, USDC, PYUSD and RLUSD, and spend them directly; deposit Bitcoin or Ethereum and KAST auto-converts them into supported stablecoins. KAST does not disclose a named issuing bank behind the card.

Availability and who can get it

The card runs on Visa and works anywhere Visa is accepted worldwide, online and in person. Getting one is another matter.

• KYC is mandatory. There is no no-ID tier; you verify your identity in the KAST app and select your country from a supported list. KAST is unavailable in restricted countries, and it does not publish that list.
• Global account, uneven reach. KAST offers a global US-dollar and euro account, but availability of services varies by jurisdiction.
• “Instant” has an asterisk. The virtual card is issued instantly, but that is issuance speed only; signup, identity verification and funding all come first.

Who it is for

Get it if you spend mostly in US dollars, already hold stablecoins like USDT or USDC, want an instant virtual card with fee-free Apple Pay and Google Pay, and are comfortable letting a custodian hold your funds.

Skip it if you want self-custody, if much of your spending is in non-US-dollar currencies where the 0.5% to 1.75% FX fee has no waiver, if the “5% cashback” headline is what drew you (the real cap is 3%, and only at $10,000/year), or if you need a named, disclosed issuing bank behind your money.
