✦ Key Insight

The TxID is one of the most useful pieces of evidence when troubleshooting deposits, withdrawals or transaction status with a wallet or exchange.

✕ Common Misconceptions

A TxID is not a password or private key. It is generally public and does not give someone control over the transferred funds.

Detailed Explanation

After a transaction is broadcast, blockchain software derives or assigns an identifier that can be used to find that transaction. Users commonly paste it into a block explorer to check status, addresses, amounts and other public transaction data.

In Practice

“An exchange support team may ask for the TxID of a deposit that reached its address but was not credited because a memo was missing.”
