Why choose this card
Start with Standard for modest USD spending without membership fees.
A good fit if
Choose Standard if supported stablecoin funding suits you and eligible monthly USD spending stays around or below $2,000.
The tradeoff
The 1.5% reward stops after $2,000 monthly; credits cannot leave KAST, and non-USD fees can consume rewards.
Consider X only when higher eligible spending and useful benefits justify its $1,000 annual fee.

Same spending. What is left?
Three cases using published terms. Add your funding costs to see what remains of the reward.
Assumes you use 100% of the reward.
Adjust reward use (optional)
Leave 100 if you will use it all. If you expect to use $5 out of a $10 reward, enter 50. This is how much of your reward you will use, not the card’s earning rate. For expiring rewards, consider what you can use before expiry.

Blank means unknown. Enter 0 only for costs that do not apply.

Standard earns 1.5% only on the first $2,000/month, capped at $30. Non-USD fees use 0.5–1.75%, plus $0.10 per purchase below $25. Cashback is card-spending credit; points and withdrawable cash are not added.
Assumptions and official evidence
Assumes an approved card and eligible retail purchases. Inputs are USD equivalents, without live FX. Taxes, ATM, borrowing, excluded merchants and refunds are outside this calculation.
One-time issuance and shipping are spread over 12 months for comparison. KAST virtual issuance varies $0–$2 by region.
Issuance/shipping per month: $40.00 ÷ 12

Before you apply
Check regional termsOfficial guidance asks users to check supported countries during signup. Country-level issuance is not confirmed here.
Regional availability is not individual approval. Figures refer to the selected card/plan; check tier, identity-document and delivery conditions.
Refunds & support
- Cancellations, refunds and support
- Request the purchase refund from the merchant and obtain confirmation. If the original charge is Pending/Authorized, a refund may await clearing; check its status in Transactions first.
- How long does it take?
- Typically 10–15 business days after merchant approval; some cases take up to 30 business days. After 30 business days, confirm merchant processing and ask Concierge to trace it with the refund reference.
- Where is it returned?
- Refunds return to the KAST wallet balance. The public refund FAQ does not specify MXN/BRL refund exchange rates; retain both purchase and refund USD amounts.
- Cancellation and subscriptions
- Delete a virtual card via Card → More → Cancel card. Ask Concierge separately about an unshipped physical-order refund and ending paid Premium/Private membership under your applicable terms.
- Declined or unfamiliar transactions
- Check balance, freeze status, limits, CVV and PIN. Insufficient-balance declines cost $0.50, so avoid repeated retries; send timestamp, amount and merchant to Concierge if unresolved.
- What to prepare for support
- In Concierge chat, type Talk to a human, or email support@kast.xyz from your registered address. Include transaction/refund references and the merchant’s response.
