You and your friends already spend money every day on groceries, subscriptions, travel, coffee, and more.
With KAST referrals, that everyday spending can help you earn rewards.
This May, KAST is adding more ways to earn through referrals, milestone bonuses, Premium access, and social rewards.
How KAST referrals work
Three steps. One path. No complicated rules.
- Share your referral link from the KAST app.
- Your friend signs up, completes verification, and activates their card.
- Your friend spends within 45 days from their KYC date.
As they reach eligible spend milestones, you can earn referral rewards of up to $250 per Base Referral.
When a referred friend reaches $500 in eligible spend, they become a qualified referral. That can unlock bigger milestone rewards when you refer more friends.
The more qualified friends you refer, the more rewards you can earn.
| Friends referred | What you unlock |
|---|---|
| 1 friend | Up to $250 in referral rewards |
| 5 friends, each spending $500+ | +$100 milestone bonus on top of your per-friend rewards |
| 10 friends, each spending $500+ | 6 months of KAST Premium, excluding the physical metal card |
Eligible rewards can stack. Refer 10 friends and you could earn up to $2,500 in referral rewards, $200 in milestone bonuses, and 6 months of KAST Premium, excluding the physical metal card.
The Premium unlock
Refer 10 friends who each spend at least $500, and you get 6 months of KAST Premium.
You get Premium benefits, with the physical metal card excluded.
No subscription fee. No upgrade purchase. You earn your way in.
Spots are limited to the first 10 people who hit this milestone.
