Transaction ID

A transaction ID is composed of the payer account ID and the timestamp in seconds.nanoseconds format ([email protected]). You are not required to generate a transaction ID for every transaction type as the SDKs generate them when submitting transactions.
Schedule Transaction ID
Scheduled transactions have a schedule flag in the transaction ID ([email protected]?schedule).
Child Transaction ID
Child transactions are transactions that were triggered by a parent transaction. Child transactions have a nonce populated in the transaction ID after the timestamp. The nonce value for the parent transaction ID is 0. The transaction ID (payer and timestamp) is the same as the parent transaction for each child transaction. Each child transaction adds a nonce value to the parent transaction ID. For example, a parent transaction with one child transaction would result in the child transaction having a nonce value of 1 ([email protected]/1). The parent transaction ID for the child transaction would be [email protected].
