Transaction hash
What it may indicate
A transaction hash is the unique identifier of a single transfer on the blockchain. Anyone who has this code can look the payment up and check where the funds went. In an investigation the transaction hash is often the starting point: it proves that a transaction actually took place and it is the point from which the route of the coins can be traced further.
What is a transaction hash?
A transaction hash, also called a transaction ID, is a long string of letters and numbers attached to every confirmed transaction. The code is unique and never changes. You can find it in your wallet or at the exchange where you made the transfer, and you can enter it into a public blockchain explorer to see the addresses, amounts and timestamps involved.
Where do I find my transaction hash?
In the transaction history of your wallet or exchange, every transfer shows a transaction hash or transaction ID. You can copy that code and paste it into a blockchain explorer to view the details of the transaction.
