When a crypto transfer seems to be taking too long, the TxID is the one piece of information that lets you and support look at the same transaction. Here is what it is, where to find it and how to use it.

A TxID, short for transaction ID and also called a transaction hash, is the unique identifier of a transfer on the blockchain. Think of it as a tracking number: one transfer, one TxID. Two people can look at the same TxID and be sure they are talking about the same transaction, not one with a similar amount or a similar time. That is why it matters more than a screenshot of an amount.
The sending side gives you the TxID once the transfer is broadcast to the network. If you send from a wallet or an exchange account, look in the withdrawal or transaction history for the entry with that transfer. If someone else is sending you funds, ask them for the TxID rather than a description of the payment. Copy it as text, because a hash is a long string of characters and is easy to mistype by hand.
A block explorer is a public page that shows what is happening on a blockchain. Paste the TxID into its search field and it shows the transfer's status and its confirmations. Use an explorer for the same blockchain the transfer was sent on, since a hash from one network will not be found on another. Comparing what the explorer shows with what your wallet shows is the quickest way to tell whether the transfer is still on its way or is already confirmed.
First check the TxID in a block explorer. Deposits to Nexus Pay are credited automatically after the network confirms them, which takes from a few minutes to about an hour depending on the blockchain, so a transfer that is still waiting for confirmations is not yet a problem. Also check that the amount is not below the minimum deposit for that network, which is shown in the app, because smaller deposits are not credited. If the transfer is confirmed and the deposit still has not appeared, contact support and give them the TxID: it is what they use to trace a deposit that has not been credited.
| Situation | What the TxID gives you | What to do next |
|---|---|---|
| Transfer just sent | A unique reference to this transfer, provided by the sending side | Save it right away |
| Waiting for confirmations | Status and confirmations in a block explorer | Wait and check again |
| Deposit confirmed but not credited | A way for support to trace the deposit | Contact support and send the TxID |
| Sent to the wrong address or network | A record of what happened, nothing more | Nothing can reverse it, so verify before sending next time |
No. Blockchain transfers are irreversible, and nobody can bring back a transfer sent to the wrong address. The same applies to the network: each deposit address belongs to one network, and a coin sent through a different network than the address was issued for will not arrive and cannot be reversed. The TxID lets you see what happened to the transfer, but it does not undo it. Check the address and the network before you confirm, not after.
Save the TxID as soon as the sending side shows it, and keep it next to a few details so you can find it later:
A note in your phone or a spreadsheet is enough. If you top up a Nexus Pay wallet, whose deposit addresses are tied to a specific network, having the TxID at hand means you can answer support's first question without digging through old history.
