Desk verdict
Kast (KST / CAST in forums) is the business crypto-card. Put it next to RedotPay (consumer) and Mercury (fiat start-up bank). Never instead of FDIC.
Kast is a Singapore-born platform for spending USDC on Visa, with a business SKU. The user typed CAST / KST — same product. The balance is a stablecoin.
Kast lists Stablecoin account + Visa BIN under VASP / card programme partners in Singapore / global. On safeguarding we currently write: USDC is not a bank deposit. No FDIC, no FSCS, no DICGC.. Holder / issuer line: Visa BIN sponsor (rotates — confirm in-app). An AML programme is claimed. There is no IBAN-class local rail on the flags we store. We list 4 live markets on the product. As we score the sticker: monthly Free virtual · paid metal / extra cards; FX Stablecoin conversion + scheme FX; ATM On the card tariff. This desk would open it for: Teams that already hold USDC and need cards, not a first operating account.
What it does well: Business-shaped crypto card; Virtual cards for vendors; Apple Pay. What to watch: Not a bank; BIN sponsor opacity; Accounting still wants a real account. Desk score 7.3 / 10 (safety 5.8, fees 7.6, features 8.4, app 8.2). Last verified 2026-08-01. Headquartered in Singapore, Singapore; founded 2023. None of this is advice — it is a file so you can read the entity before the card colour.
Best for: Teams that already hold USDC and need cards, not a first operating account.
