When a crypto transfer is called final, it can no longer be undone. Knowing when that happens explains why deposits take time and why checking an address beforehand matters.

Finality is the moment a transfer is settled deeply enough that it is treated as irreversible. Before that moment the transfer is still being recorded by the network. After it, there is no step that takes the transfer back. In everyday terms, it is the difference between a payment that is on its way and one that is done.
Finality is not a switch that flips at one instant. It grows with the number of confirmations: the more confirmations a transfer has, the more final it is. A wallet therefore waits for a set number before it shows the funds as available. This protects the person receiving the money, because crediting a transfer that is not yet settled deeply enough would be premature.
Different networks reach practical finality at different speeds. That is part of the reason deposit times vary from one blockchain to another. In Nexus Pay, for example, deposits are credited automatically after the network confirms them, which takes from a few minutes to about an hour depending on the blockchain. The table below shows how a transfer moves from sent to credited.
| Stage | What is happening | How firm is it | What you can do |
|---|---|---|---|
| Sent | The transfer has been submitted to the network | Not yet settled | Nothing further can be corrected once it is submitted, so check the address and network before this step |
| Waiting for confirmations | The network keeps adding confirmations | Finality grows with each confirmation | Wait; the wallet does not credit the deposit yet |
| Final | The transfer is settled deeply enough | Treated as irreversible | Nobody can reverse it, even if the address was wrong |
| Credited | The wallet shows the funds after the network confirms them | Settled | Use the balance as normal |
No. Once a transfer is final, it cannot be reversed, and nobody can bring back a transfer sent to the wrong address. This includes a transfer sent through the wrong network for the address, which will not arrive and cannot be recovered. Blockchain transfers work differently from a card payment that can be disputed. The safeguard is your own check before sending.
All the useful checking happens before you confirm the transfer. Go through this short list:
If something looks wrong, stop at this stage, because later there is nothing left to change.
Nexus Pay is a crypto wallet with a Visa card, opened inside Telegram. USDT and USDC can be deposited via TRC-20, ERC-20, BEP-20 and TON, and BTC and ETH via their own networks. Each deposit address belongs to one network, so sending a coin through a different network than the address was issued for will not arrive and cannot be reversed. The wallet credits a deposit automatically once the network confirms it, so the wait you see is the network reaching finality, not a delay added by the app.
