Cashback & rewards
KAST pays USD cashback by tier: 1.5% on the first $2,000/month at the free Standard tier, 2% on the first $10,000/month at Premium, and 3% on the first $50,000/month at Luxe. Paid tiers also earn KAST Points on top (1% Premium, 2% Luxe). Cashback appears at authorization but is timelocked 14 days before redemption, can be clawed back on refunds, and must be spent inside KAST on your next purchase rather than withdrawn.

Is It Worth It?
Best for freelancers, remote workers, and globally mobile users who earn in stablecoins and want borderless USD spending in one app. Strong for travelers thanks to wide Visa reach and physical ATM access. Not ideal for users who want self-custody, simple tax treatment, or who spend heavily in non-USD currencies where FX fees accumulate.
