KAST Card Review (September 2026): The $1,000 and $10,000 Tiers Are Real

KAST's free Standard tier pays 1.5% cashback in USD, funded from USDC, USDT, or USDe. The Premium and Private tiers above it aren't cheap: $1,000/year and $10,000/year respectively — real prices, stated plainly on KAST's own pricing table, which I checked twice before writing this because the numbers looked like they might be a misparse. They weren't.

What it actually pays — and the math on the expensive tiers

Standard is free and pays 1.5%. Premium costs $1,000/year for 2% cashback — half a point more. Private costs $10,000/year for 3% — one more point on top of Premium. Here's the part KAST doesn't put in a table: to break even on Premium's fee from the extra 0.5% cashback alone, you'd need to spend roughly $16,700/month on the card. Private's extra point over Premium needs roughly $83,300/month to pay for itself. Neither tier is a cashback play — they're buying KAST Points multipliers, concierge access, and a metal card, not a better rate at any spend level a normal person hits.

Standard's 1.5% is capped at your first $2,000/month of spend, confirmed directly on KAST's own fees page. Past that, spend stops earning cashback for the rest of the month.

Regions: I've spot-checked a handful directly through KAST's own signup flow rather than relying on its website, which doesn't state coverage clearly. Confirmed working: US, Australia, UK, and France (as an EU proxy). Confirmed NOT working: Canada. KAST's app shows a long country list beyond that — most major markets look covered, but treat anywhere not listed above as unconfirmed rather than assumed.

ATM withdrawals cost $3 + 2% per transaction across every tier — no tier discount on that one, which is worth knowing since some competitors waive ATM fees at their top tier and KAST doesn't appear to.

Card issuance itself isn't a flat number — it depends on virtual vs. physical. Your first two virtual cards are free, additional ones are $2 each. Standard physical cards are free too, but shipping costs a real $40, confirmed on KAST's own blog. There's no monthly membership billing at all, confirmed the same place — Premium and Private are annual-only, exactly as the pricing table shows.

Hands-on

I've gone through KAST's signup flow myself — virtual card, physical is next. Confirmed firsthand what the site doesn't state clearly: choosing United States as country of residence unlocks the full feature set (fiat transfers, the spending card, crypto send/receive, KAST savings) with no gating I could see. Signup also asks for a referral code on a dedicated full-screen step before you can continue — easy to skip past without one. Mine is OWS9Q04D, which takes $100 off a Premium membership or $1,000 off Private and does nothing at all if you stay on the free tier; full breakdown of both sides of that deal on the KAST referral code page.

Who it's for

Spenders who want a free stablecoin-funded prepaid card at a straightforward 1.5% — Standard, on its own, is a reasonable pick. Premium and Private are for people who want the concierge/status perks and have already decided cashback isn't the point.

Who should skip it

Anyone comparing Premium or Private by effective cashback rate. The breakeven spend on both is far outside normal monthly card use — if you're picking a card purely to maximize cashback, this is a Standard-tier-only card.
