getHashOfTransaction

Overview

The getHashOfTransaction method computes the hash for a signed transaction, providing a unique identifier used to track and verify transactions on the Cosmos network.

Description

This method is essential for obtaining a transaction hash from a signed transaction blob. This hash serves as the transaction's unique identifier within the Cosmos blockchain, aiding in transaction verification and tracking.

Request Parameters

Name	Type	Required	Description
`networkIdentifier`	object	Yes	Identifies the Cosmos blockchain and network details.
`blockchain`	string (from networkIdentifier)	Yes	The blockchain identifier, typically "Cosmos".
`network`	string (from networkIdentifier)	Yes	The network name, e.g., "cosmos-mainnet".
`subNetworkIdentifier`	object (from networkIdentifier)	No	Optional sub-network identifier object.
`network`	string (from subNetworkIdentifier)	Yes	The name of the sub-network within Cosmos.
`metadata`	object (from subNetworkIdentifier)	No	Metadata associated with the sub-network.
`signedTransaction`	string	Yes	The signed transaction blob for which the hash is to be calculated.

Returns

Field	Description
`transactionHash`	The hash of the signed transaction, serving as its unique identifier.
