KAST is strongest when you fund with supported stablecoins, spend in USD or with low FX drag, and can use the cashback without overpaying for a tier you do not need. The three June 2026 promotions this page used to track have all ended: Matchday 2x cashback on July 19, 2026, Ads Cashback on July 31, 2026, and the 0% FX card-spend promotion on August 31, 2026. Judge KAST on its standing fees and cashback, and check the official promotions page for anything newer.
What is KAST Card?
KAST is a crypto card and account product built around stablecoin deposits and card spending. The official card page presents Standard, Premium and Private tiers, with card materials, cashback, KAST Points on higher tiers, Apple Pay or Google Pay support, physical cards, and ATM access.
The key reader action is simple: open the official card page, select the card tier you are considering, then compare the fee page before ordering a virtual or physical card.
Official-site checks before opening an account
Do not stop at the KAST landing page. Open the card product page first, then the fee table, then the app or account screen where the card tier and country availability are shown.
Where to check in the official flow
KAST fees that decide whether it is worth it
Standard has a $0 annual fee, while Premium and Private are paid tiers. The official fee table (updated 2026-09-01, checked 2026-09-25) lists Premium at $1,000 a year and Private at $10,000 a year, Standard physical card shipping at $40, non-USD FX at 0.5-1.75%, ATM withdrawals at $3 plus 2% (up to $250 per withdrawal, 3 withdrawals or $750 per 24 hours), and a conversion fee for non-stablecoin deposits that varies by token and is shown in the app before you confirm.
That means KAST can look excellent for stablecoin users, but expensive if you deposit volatile tokens that are automatically converted or if you use ATMs often. The 0% FX promotion ended on August 31, 2026, so model the normal FX row for all non-USD spending.

0% FX promotion: ended August 31, 2026
This promotion ended on August 31, 2026. Card spend from September 1, 2026 pays the normal 0.5-1.75% FX fee. The section below is kept as a record of how it worked. KAST's 0% FX promotion terms said qualifying card-spend transactions had to be completed between June 1 and August 31, 2026. The offer was not worldwide, only selected eligible markets qualified, and users were told to contact Concierge to confirm eligibility.
The mechanics: FX was still charged at the time of spend, then a promotional credit equivalent to the FX fee could be applied after verification. Deposits, transfers, reversals, refunds, chargebacks, declined transactions and failed transactions did not qualify.
KAST Matchday 2x cashback: ended July 19, 2026
This campaign ended on July 19, 2026, and its terms page is no longer published. KAST's Matchday campaign ran from June 11, 2026 at 00:00 UTC to July 19, 2026 at 23:59 UTC. Eligible users opened the Matchday card in the KAST app, submitted one pick before kickoff, and a correct pick unlocked 2x cashback on eligible KAST card spend for 24 hours from 00:00 UTC the next day.
A similar mechanic returned on September 1, 2026: KAST's help centre describes a daily Rock Paper Scissors game in the app where a win doubles your tier's usual cashback rate for 24 hours from 00:00 UTC, subject to the normal caps and exclusions.
KAST Ads Cashback: ended July 31, 2026
This campaign ended on July 31, 2026, and its terms page is no longer published. KAST's June 15, 2026 blog described a campaign from June 15 to July 31, 2026 in which eligible KAST customers could earn 10% cashback on eligible TikTok Ads, Meta Ads, or Google Ads payments made with a KAST Card, subject to market caps and a reward pool.
A separate offer for business accounts is listed on KAST's promotions page (checked 2026-09-25): from September 1 to October 31, 2026 at 23:59 UTC, ad spend (MCC 7311) paid with a KAST Business Card earns 5% total cashback. It does not apply to personal KAST Cards.
Cashback and breakeven logic
KAST's official fee table shows USD cashback by tier and monthly caps: 1.5% on the first $2,000 of monthly spend on Standard, 2% on the first $10,000 on Premium, and 3% on the first $40,000 on Private. For a quick check, do not start with the highest reward rate. Start with your expected monthly card spend, subtract FX or conversion costs, then compare the result with any annual membership fee.
FX could be $5 to $17.50. A 1.5% cashback headline is $15 before considering caps, exclusions, and live issuer terms.
This is a simplified reader-side estimate, not a guarantee.Stablecoin deposits are listed as 0%, while non-stablecoin auto-conversion carries a fee that varies by token and is shown before you confirm.
Complete the KAST decision in three checks
Use the same order every time so the cashback headline does not hide conversion or ATM costs.
Start with Standard unless your expected monthly spend clearly justifies a paid tier.
Check non-USD FX, non-stablecoin deposit conversion, ATM, small transactions, and physical-card shipping.
The 0% FX promotion ended on August 31, 2026. Check the official promotions page for current offers and their end dates before counting on them.

Which records should I keep after using the card?
Keep the official page screenshot, application or KYC status, funding transaction, card statement, fee row, cashback or points entry, timestamp, currency, amount, and any TXID or statement number. Store them by month so support checks and later tax review are easier.
