KAST turns stablecoin balances into money you can spend today. It issues Visa cards, virtual and physical, so holders of USDC and similar assets pay at regular merchants without routing everything through a bank first. The app also lets people hold value, send funds to others, and put idle balances into vaults that earn yield while the money waits to be spent.
The tool fits anyone who gets paid in stablecoins, works across borders, or travels often and wants to skip the usual foreign exchange markups on daily cards. Freelancers paid onchain, digital nomads, and Solana users who already move USDC quickly and cheaply get the most out of it. People who spend enough to justify a tier upgrade gain higher cashback rates and bigger limits on top.
Getting started is simple. A user signs up, verifies identity, and deposits USDC or USDT from Solana, Ethereum, or several other chains. Solana transfers land fast and cost little, which matters for anyone moving stablecoins often. A virtual card shows up in the app right after funding, ready to add to Apple Pay or Google Pay for immediate spending. A physical card ships for those who want to tap in stores, with higher tiers unlocking metal or gold designs. Every purchase earns real USD cashback, credited back to the balance rather than tracked in points, at rates that scale from 1.5 percent to 3 percent depending on membership tier.
What sets KAST apart from a typical crypto debit card is the combination of broad chain support, quick cashback that lands in real dollars, and vaults that keep unspent balances working instead of sitting flat. Most crypto spending tools force a choice between holding value and using it. KAST lets stablecoins stay stable, earn a bit while idle, and convert into everyday purchases the moment a card gets swiped.
Kast Card Key features
-
Instant Virtual Card
A virtual Visa card appears in the app as soon as identity checks clear. You add it to Apple Pay or Google Pay and start spending online or in stores the same day, no plastic in the mail required.
-
Real Cashback on Purchases
Cashback pays out in actual dollars, not points, and lands back in your balance fast. Rates run from 1.5 percent at the base tier up to 3 percent at the top tier, with monthly caps that grow as you move up.
-
Vault Yield on Idle Cash
Money sitting in your account can earn through onchain strategies run by partners like Gauntlet. You can move funds back to spending balance anytime you need them.
-
Solana and Multi-Chain Deposits
Send USDC or USDT from Solana for quick, cheap deposits, or use Ethereum, Tron, Polygon, Avalanche, and other chains. Non-stable assets like SOL or BTC convert automatically when they land, with fees shown before you confirm.
-
One App for Spend and Transfer
The app handles card spending, instant transfers to other users, and fiat on/off ramps through ACH, SEPA, or wire. You skip juggling separate wallets and banking apps for the same tasks.
How to use Kast Card
-
Download the KAST app
Get the official app from the Apple App Store or Google Play Store. Avoid third-party links and download only from the verified store listing.
-
Sign up and verify identity
Create your account and enter referral code 6MHGEMGE during signup. Submit the required documents for identity verification, since approval times can vary.
-
Fund your account
Go to the deposit section, pick your asset and network, and send funds from an external wallet. USDC on Solana lands fast and cheap, but double check the network matches before you send.
-
Start spending with the virtual card
Your virtual Visa card shows up right after funding clears. Add it to Apple Pay or Google Pay and make a small test purchase to confirm it works.
-
Order a physical card
Open card management, pick a tier, and place your order. Standard cards only cost shipping now, and the card arrives by mail.
-
Track spending and cashback
Keep an eye on your balance in the app so you don't get hit with declined transaction fees. Cashback lands in your spendable balance quickly, and you can move funds out through the available on and off ramps whenever you need to.

I didn't start using KAST because of a promotion or campaign—I joined after a recommendation from a friend. After giving it a try, it quickly became one of the few crypto apps I actually use on a regular basis.

The first thing I noticed was how smooth everything felt. Creating an account took only a few minutes, the interface is clean, and navigating the app is effortless. Whether you're checking your balance, managing your card, or exploring features, everything is easy to find.
What keeps me using KAST, though, is how active the team is. They don't just build a product—they consistently create new ways for users to benefit, both online and at real-world crypto events.
Because of experiences like that, I've naturally introduced KAST to friends and people in my community. Since I use the card for everyday spending, it's easy to recommend something I've personally found useful. -
I use @KASTxyz
View on X ↗
I've been using it for everything since 2024, and it's essentially the only card I rely on.
You can still accumulate points, which at this stage will likely translate into equity in KAST or a token (Q4).
The team is strong, and the CEO actively listens to and acts on feedback.
They also offer cash back.
You can also deposit USD into the account, earn returns through the Alpha Vault or the Prime Vault (3-4%), and receive a U.S. bank account as well. -
you know what ?

ordering my Kast Card was definitely one of my favorite moments! that was when crypto finally started to feel like something I would be able to use in my everyday life instead of just using it to store in a mobile wallet!!
I also had an awesome time during the recent matchday event that was held for the World Cup and I was able to use the Kast app to provide my prediction for each match and turn 2X my cashback if I was correct!
// this was reeeeeaally cool for me because it enabled me to combine my love of football with real world rewards and also help bring us all together as a community at the same time //
Is Kast Card safe & legit?
KAST comes from Raagulan Pathy, a former Circle exec, and has backing from established venture investors plus licensed partners for card issuance and custody, which gives it real credibility rather than an anonymous side project. Solana users like it because deposits move fast and cheap on the network, and social proof from active spenders backs that up. The main risk sits in the terms of service: sending assets to KAST counts as a sale, so you hold an unsecured claim against the company instead of an insured deposit, meaning you could lose funds if KAST becomes insolvent.

“The TLDR and clarifications”
0/ At @KASTxyz we focus entirely on building and delivering for our customers.
I simply shouldn’t and won’t get distracted by others. Instead we’ll “shut up and ship”.
But, having said that, you are due some clarifications…
1/ You can’t hold crypto tokens on KAST yet. You can only deposit cash via bank accounts, stablecoins or convert crypto at time of deposit to stablecoins. They are then held as stablecoins securely in Bitgo and Fireblocks, including in cold wallets.
2/ For simplicity of user experience, to avoid swapping and bridging, we give users a single USD balance. You can then withdraw on multiple chains and multiple stablecoins, or cash via KAST Pay.
3/ Users have always held rights to redeem their funds at any time, and we always had a binding payment obligation to you, for what you have on our platform.
And… our T&Cs have now been updated to make this very clear, and we will make this even clearer through further reviews, especially for new products.
Updated:
https://www.kast.xyz/legal/terms-and-conditions-of-service
4/ We raised $80M in March 2026, from top tier institutional fintech investors like QED and Left Lane. We went through extensive due diligence from a Big4 over 3 months, before closing the round.
We have a very strong corporate balance sheet, and most of our fresh funding remains unused.
5/ Just a note, that many Cash or Card products in market still don’t allow you to export keys or take the seed phrase. But DYOR.
See one of the key updates in the image.
Appreciate the ongoing support of customers and community, so much left to build!

. @DTAPCAP calls @KASTxyz one of the higher quality businesses in crypto - and lays out the exact bar it still needs to clear before his fund invests
"We are, as far as I know, really the only growth stage investor in the world exclusively focused on crypto, blockchain, Web3, digital assets. We don't do VC. We look at companies with roughly 40 to 50 million in revenue and we want to buy them for about 5 to 10 times revenue"
"Kast is a little small. The growth of the business has been tremendous in the last two years, but it's not quite there yet. It's on our radar"
"We think it's one of the higher quality businesses doing what they do, but it wouldn't quite work yet. Maybe next year. They're on the cusp - that's why I don't have a full answer"

Over 4000 people picked >10 right, and 3 even got 17 correct in the @KASTxyz World Cup competition.
But you only needed 10 right, and there is a winner going to the World Cup Final!!
Keep picking though, double rewards for right picks and 6x for any Brazil 🇧🇷 win.
Honestly, pretty damn cool 😎
