From Crypto Exchanges to Everyday Spending With KAST

You’re in a restaurant. The bill arrives. The server asks if you’re paying by card.

If you're money is on a crypto exchange, this is a problem. You can't easily spend it.

With KAST, that's not the case though.

You can open KAST, transfer crypto from your exchange, and pay with your phone. In just a few taps, the bill is settled.

From exchange balance to paid bill in minutes

Here’s how you can move only what you need into KAST to pay the bill. Keep the rest where it is, and choose one of two simple options.

If you already hold stablecoins

Send supported stablecoins to KAST and spend them.

If you hold crypto

Send crypto to KAST Convert and we'll automatically turn it into stablecoins for you.

KAST supported assets

Supported cryptocurrencies

  • 20+ cryptocurrencies
  • Includes SOL, BTC, ETH, PENGU, UNI, and more

Supported stablecoins

  • USDC
  • USDT
  • USDe
  • PYUSD
  • RLUSD

Stablecoins matter here because the value stays steady while you pay. That way, you know what you’re spending.

Do it once. Then it’s muscle memory.

Open KAST.

Tap Receive.

Choose what you want to receive:

  • Stablecoins: USDC, USDT, USDe, PYUSD, or RLUSD
  • Crypto: SOL, BTC, ETH, PENGU, UNI, and 20+ other cryptocurrencies

Choose from one of the supported networks, including Solana, Ethereum, Tron, Polygon, BSC, Arbitrum, Avalanche C-Chain, and TON.

⚠️ Heads up: Make sure you choose the same network in both the app you're sending the tokens from and KAST, otherwise, you risk loss of funds.

Copy the address.

Go to your exchange.

Withdraw to that address.

That’s it.

What happens after you send

If you send stablecoins, they arrive on the network you chose. Once the deposit confirms, it can support your available KAST Card spending limit.

If you send crypto, KAST converts it into stablecoins for you. You see the rate before you send, and the conversion happens after the deposit confirms. The rate you see already includes fees.

You don’t need to bridge assets, swap manually, or use a decentralized exchange (DEX). You move funds once, and you’re done.

Common mistakes to avoid

Most deposit mistakes happen for one reason: selecting the wrong network.

Before you send, check the network in both apps. The network you pick in KAST must match the network you select on your crypto exchange. If KAST shows Solana, withdraw on Solana. If KAST shows Ethereum, withdraw on Ethereum. If they don’t match, you risk losing your funds.

Next, confirm the asset. Send the same token KAST shows on the Receive screen.

Also, keep the following in mind:

  • Use the fresh address KAST shows you. Don’t reuse old saved addresses.
  • Check minimums and limits before you send.
  • If a network requires a memo or tag, include it. XRP and Stellar may require this.

KAST shows these checks on the Receive screen. Match the network first, then send.

Why this flow matters

A crypto exchange is built to buy and trade assets, not to help you pay at checkout. A DEX is even further from that world. Card payments require regulated issuers, fiat settlement rails, and compliance systems, so decentralized trading venues generally do not issue cards directly. Some products get marketed as “DEX cards,” but they still route funds through third party card issuers and extra steps, so the setup is not as direct as the label sounds.

Even on the centralized side, many exchanges still don’t give you a clean “spend now” path. If an exchange offers a card, you often need to move funds into a separate card or spending balance first. KAST keeps the flow simple: you transfer funds into KAST, receive money in a spending account, and  pay just as you normally would.

KAST vs other ways to pay from crypto

What you’re trying to do Typical flow Why it gets annoying What KAST changes
Pay using a DEX Swap, bridge, route through another service No direct card issuance, more moving parts One receive flow, then spend
Pay using a CEX Withdraw, move into a card wallet, then pay Cards are not universal, steps vary Same flow across networks and assets
Pay using KAST Receive stablecoins or deposit crypto for auto conversion Network choice still matters Clear receive screen, then card spend

One last thing

It's best to set up KAST before you need it. That way, when the time comes to check out or pay a bill, you can just swipe your card or tap with Apple Pay and Google Pay.

KAST Adds In-App Affiliate Sign-Up and Portal Access

You’ve probably talked about KAST without even thinking about it. Maybe someone asked how you receive USD from abroad. Maybe they were curious how you actually spend stablecoins in daily life. Maybe you dropped your referral link in a group chat and moved on.But you never really know what happens next.Now you can turn those casual conversations into something structured and measurable — without creating a separate account or searching for signup pages. You can apply to the KAST Affiliate Program directly inside the app.There are no extra logins, no separate platforms to manage, and no added friction. It starts exactly where you already are.Why Apply Inside The App?Most affiliate programs sit outside the product experience. You usually have to search for the right signup page, create a separate login, manually connect your referral code, and then switch between different dashboards just to keep track of everything. It often feels disconnected from the product you’re actually using.With KAST, the process starts inside the app. You simply go to Home → Refer → Become an Affiliate.Because it’s built into your existing account, your email stays aligned, your referral code remains the same, and your identity is already verified. There’s no need to recreate information or manage a separate profile.Keeping everything in one place reduces friction, minimizes back-and-forth during review, and makes the whole process more straightforward.How The Application Process WorksStep 1: Apply From The AppOpen your KAST app and go to:Home → Refer → Become an AffiliateThen:Tap ReferTap Become an Affiliate (top corner)The application form opens in your browser.It’s short and focused. You’ll be asked for:Your affiliate code (from the app)Name, phone number, and KAST emailPrevious affiliate experience (if any)Optional links (Telegram, LinkedIn, etc.)Your main channels and audience countriesA short note about how you plan to promote KASTSubmit the form.

Some people sign up — but you don’t know how many, or why.After applying through the app and getting approved, that changes.Now you can see:Which posts generate sign-upsWhich use cases resonate mostWhether your audience responds more to the KAST Card or Local PayoutsInstead of guessing, you have data.Instead of casually sharing, you’re running something structured.How This Fits Into the KAST EcosystemMost affiliates promote what they already use. In practice, that means they talk about real things they do in KAST. For example, they receive USD into their KAST Global USD account, hold stablecoins like USDC, and spend globally with the KAST Card. They also use local payouts to convert funds into local currency when they need to.When your content reflects real usage, referrals feel natural. You are not pushing a product. Instead, you are showing how you use KAST in daily life. People understand the value because they see it in context.The Affiliate Program simply adds tracking and structure to what you already do inside KAST.What It CostsThere is no fee to apply.If approved, commissions and rewards are visible inside the Affiliate Portal.Eligibility criteria, reward structures, and approval timelines may change and are subject to internal review.Quick Checklist Before You ApplyYou actively use KASTYou have an audience (community, social media, newsletter, etc.)You can explain real use cases clearlyYou’re willing to promote responsiblyIf that sounds like you, the process takes just a few minutes.Ready To Apply?Open the KAST app and go to:Home → Refer → Become an AffiliateOr learn more at:https://www.kast.xyz/affiliateStart in the app.Apply in minutes.Track everything in one place.
