KAST Referral Code 2026: I Don't Have One Yet — Here's What That Screen Actually Does
Last verified: 2026-07-21
I don't have a KAST referral code to give you. My application to KAST's program is still pending, and I'm not going to post a code I haven't generated and tested myself — which is the entire difference between this page and most of what you'll find searching this term.
What I can tell you, from running KAST's signup myself: there is a dedicated, full-screen step that asks for a referral code before you can continue, and it's easy to click past without one.
I don't have a personal code live for this one yet — I'm not going to post one I haven't tested myself. Sign up directly with the issuer for now; this box updates the day I have a real, verified code.
Disclosure: if I did have a code and you used it, I'd get: Tiered: one-time spend-milestone bonuses ($20–$500), a first-year subscription commission (Premium $100–200, Private $1,000–2,000), and 0.20%–0.50% ongoing cashback on referral spend — all scaling with your own affiliate tier. Rankings above aren't affected by that either way.
Where KAST asks for the code
It's not buried in a settings menu or an optional field at checkout. During signup, KAST puts the referral-code prompt on its own screen, full width, before you can proceed:
What a KAST code actually gets you
Honestly: I don't know, and I'd rather say that than guess. KAST doesn't publish the new-user referral benefit on its own site, and I don't have an active referrer account to check from the inside. If you sign up with a code from somewhere and see a stated bonus, I'd genuinely like to know what it was.
What I can tell you is what the code doesn't change. KAST's cashback rates are the same either way: the free Standard tier pays 1.5%, capped at your first $2,000/month of spend, confirmed on KAST's own fees page. No referral code changes that number, and any page telling you a code unlocks a better rate is describing something KAST doesn't publish.
What I confirmed about KAST myself
Since I can't offer you a code, here's the research that's actually worth something — all of it firsthand through KAST's own signup flow rather than from its marketing pages:
Regions. KAST's website doesn't state coverage clearly, so I spot-checked directly. Confirmed working: US, Australia, UK, and France (as an EU proxy). Confirmed not working: Canada. Anywhere else, treat as unconfirmed rather than assumed.
The US experience. Choosing United States as country of residence unlocks the full feature set — fiat transfers, the spending card, crypto send/receive, KAST savings — with no gating I could find.
The expensive tiers are real. Premium costs $1,000/year and Private costs $10,000/year. Those aren't typos; I checked KAST's pricing table twice because they looked like a misparse. Premium's extra 0.5% over the free tier needs roughly $16,700/month in spend just to break even on the fee. Full math on the KAST Card review.
Costs the fee page doesn't lead with. Your first two virtual cards are free, additional ones are $2 each. Standard physical cards are free but shipping costs $40. ATM withdrawals are $3 + 2% across every tier, with no discount at the top tiers.
Why there's no code here and there is on other pages
Three cards on this site have real, verified codes I generated from my own accounts — Tria, Avici, and ether.fi. KAST isn't one of them yet. When the application clears and I've tested a code myself, this page changes the same day and the change gets logged with a date on the change log.
Until then, you're not missing much: sign up without a code, take the free Standard tier's 1.5%, and don't pay for Premium expecting the cashback to cover it.
FAQ
Is there a working KAST referral code?
Not from me, not yet. My application to KAST's program is still pending, and I don't post codes I haven't generated and tested from my own account. Codes you find elsewhere may work — I just can't vouch for any of them.
What does a KAST referral code get you?
KAST doesn't publish the new-user referral benefit anywhere on its own site, and I don't have a referrer account to check from the inside, so I genuinely don't know. What I can confirm is what it doesn't change: the free Standard tier's 1.5% cashback, capped at your first $2,000/month, is the same with or without a code.
Where do you enter a referral code on KAST?
On a dedicated full-screen step during signup, before you can continue. It's not hidden in a settings menu — but it is easy to click straight past if you don't have one. There's a screenshot of that exact screen on this page, from my own signup.
Can I sign up for KAST without a code?
Yes. The code step is skippable, and skipping it doesn't change your cashback rate. Standard is free and pays 1.5% either way.
Which countries does KAST work in?
I spot-checked directly through KAST's own signup flow rather than trusting its site, which doesn't state coverage clearly. Confirmed working: US, Australia, UK, and France. Confirmed not working: Canada. Treat anywhere else as unconfirmed.
