KAST does one job precisely: it turns a stablecoin balance into a spendable USD Visa at 1:1 with no spread, in 170+ countries including the US, with a virtual card minutes after a two-minute KYC and 1.5% back in dollars on a free membership. That is the product sold today, re-scored on the May 2026 membership model — the 8% points headlines attached to the retired Limited and Luxe cards are history. The free tier's cashback caps out at $30 a month. The cost drag outside the stablecoin lane (0.5%–1.75% FX, $3 + 2% ATM cash, 2%–5% on volatile-crypto deposits) is real money for travelers and BTC holders. And the custody stack, with an Anjouan-incorporated app operator (KAST Tech) and the card program run through Troia Corp, asks for more trust than an onshore, insured setup — even with the issuer, Third National, now named in the cardholder agreement. Fund it with stablecoins, spend it in dollars, and the card costs almost nothing to hold while paying 1.5%. Fund it with anything else and the fees eat the pitch.
