Any transaction carried out on a blockchain will have its own specific ID, also known as a hash. Any transaction ID (TXID) you see is unique and can be checked at any time.

A blockchain TXID is created once the transaction data is hashed through SHA256 encryption twice. Once the TXID is generated, you can use it to check fees, estimated arrival time, the number of confirmations, and the wallets involved in the transaction. A TXID will always be 64 characters long (32 bytes).

Where Do I Check The Transaction ID For Bitcoin?

In order to check a TXID involving Bitcoin, go to Blockchain Explorer (or another secure blockchain transaction checker of your choice) and paste the TXID you’ve received.

A typical Bitcoin TXID will look like this.

An example:

If your Bitcoin wallet shows you a TXID, you can probably look it up right away – however, due to a quirk that came up early in the development of Bitcoin, transaction IDs sent from older bitcoin wallets will have to be reversed in order for you to be able to find them.

Where Do I Check The Transaction ID For Ethereum?

In order to check a TXID involving Ethereum or any other crypto token minted on the ERC-20 blockchain, head to Etherscan (or any other secure blockchain transaction checker), paste your TXID and go!

A typical Ethereum TXID will look like this.
An example:

Unlike Bitcoin transaction hashes, Ethereum transaction IDs are searchable right away. A typical Ethereum transaction hash will start with “0x” and will also always be 64 characters long.

A Blockchain hash can be checked at any time – so the details of any transaction can be looked up by you later as long as you keep a record of them.
