KAST

Name: KAST

A stablecoin neobank: hold digital dollars, spend them anywhere with USD cashback.

KAST behaves like a global dollar account built on stablecoins. Deposits in USDT, USDC or USDe become a USD balance at 1:1, spendable through a Visa card in 170+ countries. Cashback is paid in dollars rather than a volatile token, which makes the rewards easy to value. It is a strong fit for anyone earning in stablecoins - freelancers, remote workers and users in high-inflation countries.
