Crypto transfers can't be undone, so the first one is the best moment to make your mistakes cheap. Here is what a test run checks and how to do it.

Yes, and the reason is simple: a blockchain transfer cannot be brought back. If the address is wrong, or the coin is sent through the wrong network, nobody can reverse it. A small first transfer means that if something goes wrong, you lose a small sum rather than your whole budget. Once the test arrives, you have proof that your method works.
It checks three things at once: the coin, the network and the address. In Nexus Pay each deposit address belongs to one network. USDT and USDC can arrive via TRC-20, ERC-20, BEP-20 or TON, and BTC and ETH use their own networks. A transfer sent through a different network than the address was issued for will not arrive. A test shows you that you picked the right combination and that the crediting works as expected.
Small enough that losing it would not hurt, but not below the minimum. Every network has a minimum deposit amount shown in the app, and deposits below it are not credited. Check that figure for your chosen network before sending. Then allow for confirmation time: deposits are credited automatically once the network confirms them, which takes from a few minutes to about an hour depending on the blockchain.
The deposit is only the first step. With the same small balance you can walk through the rest of the flow:
Doing this once at low stakes means the real transfer will not be your first time. Card issuing itself requires identity verification (a document and a photo), so it is worth getting that out of the way early.
| Step | What you do | What it confirms |
|---|---|---|
| Deposit | Send a small amount above the network minimum | Coin, network and address match; crediting works |
| Swap | Exchange one coin for another in the wallet | You see the received amount before confirming |
| Load the card | Move part of the balance to the card | The transfer works and the fee matches the fee page |
| Pay | Make one online or contactless purchase | The card spends your available balance as expected |
| ATM (optional) | Make one withdrawal with a physical card | You see the ATM owner's fee before you confirm |
Very little. Swapping inside the wallet costs 0% and uses the exchange rate with no markup. Moving money to the card costs 0.1%, and card purchases cost 0%. The fee page gives an example: 1000 USDT moved to the card becomes $999.00. If you want to try an ATM, the withdrawal fee is 0.25% per withdrawal, and the ATM owner may add its own fee, shown on the screen before you confirm. Since the fee is charged per withdrawal, one test withdrawal is enough; repeating small ones only adds cost.
You repeat the same steps with a larger amount. Nothing about the route changes: same coin, same network, same address check, same order of actions. If you use Nexus Pay, you can also set the optional four-digit access code and decide whether to freeze the card in the app when you are not using it. This is general information, not financial advice, and how much to move is your own decision.
