Overview
KAST is a Visa card from KAST Finance built around a global USD account and a stablecoin wallet, with cashback that scales by tier. The base K Card pays 1.5% on every purchase; paid premium tiers go up to 6%. KAST's pitch is breadth: 16 settlement fiat currencies, ATM coverage worldwide, and merchant acceptance across 170+ countries. The premium tiers (Luxe and Private) ship as gold metal cards with concierge-style perks for high-volume spenders.
Who KAST is best for
The base K Card is well suited to travelers and globally-mobile users who spend in lots of different currencies. The premium tiers (Premium, Limited, Private) only make sense if you spend enough each month for the elevated cashback to outweigh the annual fee — typically tens of thousands of dollars per month before the math turns positive. If you're a low-volume spender, stick to the K Card.
Fees, in detail
KAST charges 0% FX on spending in your home currency and up to 1.75% on foreign currencies (Standard tier). There's a $0.10 flat fee on low-value purchases. Standard tier carries no annual fee. Premium ($1,000/yr), Limited ($5,000/yr), and Private ($10,000/yr) tiers carry significant annual costs in exchange for higher cashback ceilings and additional perks. Virtual cards cost $2 to issue; physical Standard cards are $40 one-time shipping.
Cashback and rewards
KastPoints accrue on every purchase and redeem for SOL. The base K Card earns 1.5%, Premium 4%, Limited 4%, and Luxe 6% (season 6 rates). Because rewards are redeemed for SOL rather than a card-specific token, their fiat value tracks the Solana market. Premium-tier cashback is real, but the annual fees on those tiers are high enough that they only pay off above significant monthly volume.
