Change Output

In cryptocurrency transactions, the change output refers to the portion of the input amount that is not used as the transaction value and is returned to the sender's wallet as change.

When a user initiates a transaction, they typically use one or more unspent transaction outputs (UTXOs) as inputs. These inputs may contain more funds than the desired transaction amount. To ensure that the entire input amount is utilized, the change output is automatically generated by the wallet software and sent back to the sender's address, effectively returning the unused portion of the input. The change output is an essential component of cryptocurrency transactions, as it allows for efficient utilization of available funds and prevents the loss of any remaining balance after a transaction is completed.
