A transaction hash/id is a unique string of characters that is given to every transaction that is verified and added to the blockchain. The transaction hash allows us to look up the transaction on a blockchain explorer and see all related details such as sending address, receiving address, amount, and time stamp.
You can find and copy your transaction Hash inside K5 Wallet as follows:

Inside the token Account, you can see a list of all your transactions. Tap on the target transaction.
In the transaction screen, you can see all the transaction details. Tap on the copy icon beside the Hash to copy it to the Clipboard.
