Custodial stablecoin account, Visa card, and crypto-conversion platform

KAST's July 2026 platform terms define the card as credit secured by deposited assets and say crypto sent to KAST becomes its property in exchange for a USD payment claim; balances are not insured deposits. Its August help guide says purchases deduct wallet funds immediately and are not credit. The public descriptions conflict, so confirm the issued partner agreement before relying on its payment model. Card signup also depends on the live country selector.
Platform terms effective 7 July 2026: KAST Tech identity and Comoros registered address; non-bank and uninsured balance status; transfer of asset ownership for a USD payment claim; partner custody; a credit card secured by deposited virtual assets; and live country-selector eligibility.
Fee guide updated 1 September 2026: annual tiers, card pricing, FX, cashback and KAST Points, ATM charges and limits, stablecoin conversion, fee variability by region/program, and the precedence of platform terms over conflicting disclosures.

Updated 9 August 2026: card signup is not available in every country and residents must check the live selector; VPN use from unsupported countries violates the terms.

Updated 9 August 2026: Visa merchant acceptance; the guide says purchases immediately deduct wallet funds and use the cardholder's own funds, not credit. This conflicts with the platform terms' definition of collateralized credit and does not establish local issuance eligibility.
Older agreement still lists up to 2% non-USD FX and USD 0.20 on non-USD purchases below USD 25, conflicting with the newer September 2026 fee guide's 0.5%-1.75% FX and USD 0.10 small-transaction fee.
