How to Move Money from Your Bank Account to Your KAST Card

You’ve got money sitting in your bank account. You’ve got your KAST card ready to use. And you expect moving money between the two to be simple.

Then you try it.

The transfer says “sent,” but your balance hasn’t changed. The amount that arrives isn’t exactly what you expected. And somewhere in the process, you’re asked for details that don’t sound familiar.

At that point, it starts to feel like you’re missing something.

You’re not.

You’re just moving money between systems that don’t behave the same way. Banks and crypto rails all follow their own rules. When they connect, things can feel inconsistent unless you know what to expect.

Once you understand how money moves into KAST, it becomes straightforward. Not instant every time. Not identical in every region. But predictable enough that you’re not guessing.

How to Move Money From Your Bank Account into Your KAST Card

When you move money from your bank to your KAST card, you’re not doing anything unusual. You’re funding a balance that becomes available to spend.

In most cases, once the money reaches your KAST account, it’s already usable. The part that feels confusing usually happens before that moment, not after.

What matters is how the money gets there.

Different routes use different rails. That’s where timing, fees, and small inconsistencies come from. Once you recognize which route you’re using, things start to make more sense.

Best Way to Move Money from Bank Account to Your Card

Even if the app shows a single “add funds” button, there are usually a few underlying paths.

Bank Transfer Deposit (Standard Fiat Route)

This is the most familiar method.

You send a bank transfer using the details provided in KAST. Once it arrives and clears, your balance updates and becomes available to spend.

This is usually the best option when you care about predictability, or you’re moving a larger amount. It behaves the way most people expect banking to behave, just with more patience required.

What to expect:

• Not instant: Banks process transfers in batches, and cutoffs vary by bank and country.
• Occasional checks: Some transfers get held for compliance or review. That’s normal on bank rails.
• Possible deductions on international routes: Intermediary banks can take fees along the way, which can make the received amount slightly different from the sent amount.

Stablecoin Deposit (Faster Route)

If you’re comfortable with crypto transfers, this route is usually quicker.

You convert fiat into stablecoins using a service you trust, then send those stablecoins to your KAST account. Once the transfer confirms, your balance updates.

This avoids some of the friction of traditional banking rails. You’re not waiting on bank cutoffs or intermediary processing.

But one detail matters more than anything else:

The network has to match.

USDC on one network is not the same as USDC on another. If you send on the wrong network, the transfer won’t land where you expect. That’s not a small detail. It’s the whole transaction.

If you match the asset and the network, the rest is typically straightforward.

What Can Go Wrong?

Most issues don’t come from complexity. They come from small details being slightly off.

Here are the common causes, in plain language:

• “Sent” doesn’t mean “settled.” A bank transfer can be marked as sent on your side while it’s still moving through processing windows.
• The final amount differs from what you sent. That usually comes from:
  • conversion (exchange rate or spread),
  • rail fees (bank or network fees),
  • intermediary deductions (common on international transfers).
• Network mismatch on deposits. Same ticker, different network, different asset path.

If it’s your first time using a new route, a small test transfer is still one of the simplest ways to remove uncertainty before you rely on it.

Summary

In reality, it’s usually a combination of a few things layered together.

This is why the final amount can look slightly different from what you sent.

Nothing unusual is happening. It’s just multiple systems applying their own costs along the way.

If you want clarity, the goal isn’t to eliminate fees completely. It’s to understand where they come from so you’re not surprised by them.

KAST Fees and Limits for Receiving Funds

Understanding fees upfront removes most surprises. Below is how funding works inside KAST.

Receiving Stablecoins

KAST doesn’t charge any fees for receiving supported stablecoins, regardless of which one you choose.

Receiving Fiat Bank Transfers (USD)

These are KAST-side fees. Your bank or intermediary banks may still apply their own charges.

Local Rails and Regional Costs

In some regions, local bank systems offer faster or cheaper alternatives. Below are the costs for PIX, SPEI and ARS local deposits.

PIX Transfers (Brazil, BRL)

PIX deposits and payouts include IOF, a Brazilian financial transaction tax.

SPEI Transfers (Mexico, MXN)

ARS Bank Transfers (Argentina)

Summary

You don’t need to overthink this.

Pick based on what you want most:

• If you’re moving a larger amount and want fewer surprises: use a bank transfer. Slower, but consistent.
• If you want speed and control over timing: use stablecoins, and be strict about matching the network.

Each option does what it’s supposed to do. They just prioritize different things.

How to Fund Your KAST Card Without Guessing

Moving money from your bank into KAST isn’t complicated. It just involves more moving parts than it looks like at first.

Once you understand which rail you’re using, you stop guessing. You know what step you’re in, what’s normal, and what to double-check.

You’re not sending money and hoping it works.

You’re funding your KAST balance knowing what’s going to happen next.
