Topping up a Fizardus card takes about the same time as sending a message. You send USDT from any wallet or exchange, and the balance lands on your card — ready to spend online, in stores, or at an ATM. No bank account, no paperwork, no waiting days for a transfer to clear.
Here is exactly how it works.
What you need
- A Fizardus account (open the bot and tap Start).
- USDT in any wallet or on an exchange — on the TRON (TRC-20) or Ethereum (ERC-20) network.
- Two minutes.
That’s it. You don’t need a card issued yet to top up — your balance lives on your account, and you assign it to a card when you order one.
USDT is the most popular way to fund because a stablecoin keeps your balance steady. But it isn’t the only option: you can also top up with BTC, ETH, TRX, or TON and hold and spend any of them from your Fizardus wallet.
Step 1 — Open Top Up
Inside the app, tap Top Up. Enter the amount you want to add in USD. The minimum is 50 USDT. You’ll see the exact amount to send and the deposit address.
Fizardus takes a flat 1% on top-ups funded through the payment provider. Fund from your own wallet and that 1% isn’t charged — you keep more of every deposit.
Step 2 — Send USDT
Copy the deposit address (or scan the QR code) and send USDT from your wallet or exchange. Double-check the network — send TRC-20 to the TRC-20 address, ERC-20 to the ERC-20 address. Sending on the wrong network is the one mistake that can lose funds, and it applies to every crypto service, not just ours.
Network fees are tiny: a USDT transfer on TRON usually costs a fraction of a dollar.
Step 3 — Wait for confirmation
Once the network confirms your transaction — usually under a minute on TRON — your balance updates automatically. You’ll get a notification, and the new balance shows up in the app.
If the transaction is confirmed on-chain but your balance hasn’t moved after 30 minutes, contact support with your transaction hash (TXID) and we’ll trace it.
Spending your balance
With a funded balance you can:
- Order a card — your first card is free. Pick a country, and the details arrive in Telegram.
- Top up an existing card so it’s ready for online payments, Apple Pay, Google Pay, or ATM withdrawals.
No bank ever sees the transaction, and there’s no KYC to spend. That’s the whole point: crypto in, real-world spending out, in the time it takes to send a message.
Common questions
Which network is cheaper? TRON (TRC-20) — the transfer fee is usually a few cents and it confirms fast.
Is there a maximum? Per-card top-up limits depend on the card product you choose; you’ll see them before you order.
Can I withdraw the balance back out? Balances are meant for spending on cards. If you need to move funds out, contact support and we’ll handle it manually.
