Quick verdict
Choose Rizon if…
You prioritize a non-custodial setup, want Rizon's available local-currency account and payout features, or prefer its current card rewards after checking eligibility in your region.
Choose KAST if…
You prefer a more conventional app experience, want broad international coverage, or value USD account and transfer features such as ACH and Fedwire where eligible.
The biggest difference is control: Rizon explicitly markets a non-custodial setup, while KAST is a custodial, all-in-one global money app. Fees and rewards matter too, but custody and regional eligibility should come first.

Rizon vs KAST: the differences that matter
Fees and card cost
Do not choose between Rizon and KAST from a single headline fee. Rizon has run promotional pricing for its virtual Visa, while KAST's support documentation currently describes card ordering as free. The total cost can still depend on FX, ATM use, transfers, card delivery and your region. Check the final fee screen inside each app before paying or moving funds.
Cashback and rewards
Rizon's current main card page advertises 2.5% cashback on eligible spending and also promotes RizPoints; the effective rate and any caps depend on the Rizon plan you are on. KAST advertises rewards and cashback on eligible card spend, but the exact benefit can depend on the active program, card and user eligibility. If rewards are your deciding factor, compare the rate shown in your own account rather than relying on an old promotional number.
Custody and control
Rizon explicitly describes its wallet setup as non-custodial and says wallet functionality is powered by Privy. That gives the user more direct control, but it also makes wallet security and recovery especially important. KAST is an account-based, custodial global money app: KAST and its licensed partners hold the assets for you with institutional custodians, so you do not manage keys yourself. That is more convenient, but it means trusting the company and its partners — read KAST's current terms for the exact treatment of each balance before depositing.
Bank accounts and transfers
Both products go beyond card spending. Rizon advertises local-currency accounts and payouts across multiple currencies, while KAST highlights a USD account with ACH and Fedwire plus international rails such as SWIFT and SEPA where available. The better option depends on which rails are actually enabled for your country and verification status.
Country availability
KAST currently advertises availability across 170+ countries, although individual features and payment methods vary by region. Rizon's own pages contain jurisdiction-specific eligibility language, so availability should be checked directly in the app before signup. A card that ranks better on features is irrelevant if the account or transfer rail you need is not available where you live.
Editorial check: Product claims on this page were re-checked on September 23, 2026 against the providers' official product/support pages. Because stablecoin-card terms change quickly, the app's final pricing and eligibility screen should be treated as authoritative.
