How Can I Spend Crypto Using PIX In Brazil with KAST?

You can now use your crypto to pay for everyday needs in Brazil - from your morning coffee to a night out. With KAST, you send your crypto, it automatically converts to stablecoins, and you can spend instantly anywhere using your KAST Card, Mobile Wallets, or the latest PIX integration.

After you deposit, your balance stays in USD, protecting your funds from inflation and giving you instant spending whenever you need it.

How to Get Started with KAST in Brazil

  1. Open your account and deposit stablecoins - they go straight to your USD balance at 1:1.
  2. Send other cryptocurrencies and KAST will automatically convert them to stablecoins at the best rate.
  3. Your KAST Card is ready to use in Brazil. Add it to Apple Pay / Google Pay or use your physical card at any Visa-accepted location.


3 Ways to Spend Crypto in Brazil with KAST

KAST makes it easy to spend your crypto in the real world - in any store, café, or restaurant that accepts PIX or Visa.

Option 1: KAST Card

Tap or insert your physical KAST Card and pay instantly. Your crypto converts from USD → BRL at the moment of purchase. Fast, simple, done.

Option 2: PIX Scan to Pay

Open the KAST app, scan the merchant’s PIX QR code, confirm, and pay. The app converts your crypto to BRL instantly, and the merchant receives it right away.

Option 3: Mobile Wallet (Google Pay or Apple Pay)

Use your KAST Card through Google Pay or Apple Pay for fast, contactless spending. Add your virtual card to your phone and pay anywhere with a tap.


How Do I Spend My Crypto in Brazil Using PIX?

The KAST app makes it easy to spend your crypto balance at any merchant in Brazil that accepts PIX.

  1. Scan the QR Code: Open the KAST app and scan the merchant’s PIX QR code at checkout.
  2. Review and Confirm: Your KAST app shows the BRL total the merchant receives and the equivalent USD amount deducted from your balance.
  3. All Done: The merchant receives BRL instantly.


What Are the KAST Card Fees When I Pay in Brazil?

When you pay in BRL, KAST handles the conversion from USD → BRL using a transparent market-based rate plus a 2% FX fee.

If you choose to pay in USD (when available), some merchants may use Dynamic Currency Conversion (DCC) - applying their own exchange rate, which is often higher than KAST’s.

There’s no standard transaction fee per purchase (including Apple Pay and Google Pay).
However:

  • A $0.50 declined transaction fee applies only if your payment fails due to insufficient balance.
  • For non-USD transactions below $25, a small $0.10 low-authorization fee may apply.

PIX Scan to Pay

When you use PIX Scan to Pay, your crypto is converted instantly to BRL at the market rate. There’s no transaction fee for the payment itself.

When depositing via PIX, customers are charged a total FX markup of 0.88%.

For PIX payouts, there’s a 1% conversion fee total.

For full fee details and terms, visit the KAST Fees & Conditions page.


Which Receipt Option Should I Choose at the Terminal?

When paying with your KAST Card or mobile wallet (Apple Pay / Google Pay), the terminal may ask if you want to pay in BRL (Real) or USD (Dollar).

Although it might seem logical to choose USD if your balance is in dollars, in Brazil we recommend almost always select BRL (Real).

Why You Should Choose BRL

  • Most merchants only process BRL, even if you choose USD.
  • Selecting USD triggers Dynamic Currency Conversion (DCC) by the merchant or processor - using their own (often worse) exchange rate.
  • Selecting BRL lets KAST handle the conversion, applying a transparent market-based rate + up to 2% spread.

Example: Paying in Brazil - BRL vs USD

Here’s an example from a coffee shop in Blumenau, Santa Catarina, where the same R$7.50 item was paid twice - once selecting BRL, and once USD.

Option 1: Paying in BRL (Recommended)

Detail Value
Terminal Selection BRL (Real)
Conversion By KAST
Amount Charged $1.43 USD
Exchange Rate 1 USD = R$5.24
Outcome Lower total cost, transparent market rate ✅


Option 2: Paying in USD (Merchant Conversion)

Detail Value
Terminal Selection USD (Dollar)
Conversion By Merchant/Processor (Cielo)
Amount Charged $1.63 USD
Exchange Rate 1 USD = R$4.60
Outcome Higher cost due to merchant markup (~14%) ❌

Tip : When paying in Brazil, always choose BRL (Real) at the terminal. This ensures KAST - not the merchant - handles your currency conversion, usually resulting in a lower overall cost and more transparent rates.
