Coinbase Card

The safest pair of hands in the comparison: NASDAQ-listed issuer context, FDIC-member bank card, zero fees on USD/USDC spending and no staking requirement. The trade-offs: US-only (no Hawaii), rewards rates are variable in-app only, and non-USDC crypto spends trigger auto-sell with spread and taxes.

KAST

The most complete stablecoin-spending account on the market: US/EU virtual bank accounts from anywhere, Visa Platinum cards with real 1.5% USD cashback on the free tier, instant cashback and no spending caps. Full KYC and a young operator are the trade-offs; the paid tiers only make sense for heavy spenders.
