Kast and the OKX Card are both stablecoin-first cards claiming coverage across 100+ countries, which makes them natural rivals for anyone who just wants to spend USDT or USDC.
The practical split is ecosystem: the OKX Card is tied to the OKX exchange, so its availability tracks where OKX is licensed, while Kast is a more standalone stablecoin card. Country lists for both move quickly and are provider-stated, so we mark anything we have not confirmed as unconfirmed rather than repeat a claim.
Already hold assets on OKX? Its card is the frictionless choice. Want a card that is not anchored to one exchange? Kast is the more neutral option. Fees are verified where we have paid them and flagged where we have not.
