KAST

KAST is a global USD & EUR account app with an instantly issued Visa card designed to let you hold stablecoins and spend them anywhere Visa is accepted — at 150M+ merchants worldwide. The card keeps up with you: instantly issued, globally accepted, and tightly synced to your KAST global USD or EUR account for real-time spend controls.

The product is structured as three card tiers, each with its own card type, cashback rate, and perks:

• Standard — Free. VISA Platinum. 1.5% USD cashback. 2 free cards (virtual or physical). Designs include the K Card, Solana Card, Bitcoin Silver Card, and Pengu Card.
• Premium — $1,000/year. VISA Infinite metal. 2% USD cashback + an additional 1% in KAST Points on all spend. 1 free Premium metal card (virtual & physical) plus the Standard allowance. Designs include the X Card, Solana Illuma, Bitcoin Black, and Pengu Black.
• Private — $10,000/year. VISA Infinite plated gold. 3% USD cashback + an additional 2% in KAST Points. VIP concierge with exclusive access to the KAST senior team. 1 free Plated Gold card plus 2 free cards from any other tier.

Cashback is paid in real USD that you can spend immediately on the next purchase — no catalogs, no conversions, no waiting periods. Cashback credits the moment a transaction is authorized, and works on every eligible card spend: local groceries, international purchases, online or in-store.

The KAST app doubles as a full funding hub. Users can deposit USD via bank transfer (with real-time tracking and clear upfront fees), deposit stablecoins from Ethereum, Tron or Arbitrum (instantly converted to USD inside KAST with no hidden spreads), deposit non-stable crypto and convert to USD instantly, or send from exchanges and wallets with QR-code or address-copy flows. The card is fully tokenized — merchants only see a secure token while the real card number stays hidden — and supports ATM withdrawals at any Visa-supported ATM around the globe.

KAST announced an $80M Series A, putting it among the better-capitalized stablecoin-card startups. The company also offers a Business program and Earn feature for yield on deposits, positioning itself as a complete crypto-to-fiat spending platform rather than a single card product.

FX & ATM fees

• Stablecoin deposits convert to USD/EUR with no hidden spreads — the rate is shown before you confirm.
