FAQ

No. KAST is not a bank and does not take deposits as one. It is a payments app that issues cards through regulated partners, so your money moves on established card networks while the account itself sits with KAST.

Yes. You can deposit stablecoins such as USDT and USDC across 10+ chains, along with PENGU and 25+ other coins. Balances are spendable straight from the card — there is no separate conversion step.

People who hold digital dollars and want to spend them like any other money — freelancers paid across borders, frequent travellers, and anyone whose income and spending happen in different countries.

The card works at over 150 million merchants and at ATMs across more than 170 countries — anywhere the card network is accepted, in stores, online, and through Apple Wallet or Google Wallet.

Sending money between KAST accounts is free. Card tiers differ in what they cost to hold, and transfers to external bank accounts show the exact amount, the cost and the arrival time before you confirm.

KAST uses identity verification, encryption, device-level security, and real-time fraud monitoring to protect your account. Financial services are provided through licensed and regulated partners, and you can enable additional protections like biometric login and multi-factor authentication in the app.
