getTransactionByHash

public static com.google.common.base.Optional<org.bitcoinj.core.Transaction> getTransactionByHash(org.bitcoinj.core.Transaction tx,
                                                                                                  byte[] txHash)

Parameters:

tx - The transaction to search

txHash - The transaction hash to match on

Returns:

The matching transaction if present

checkEssentiallyEqual

public static boolean checkEssentiallyEqual(org.bitcoinj.core.Transaction unsignedTransaction,
                                            org.bitcoinj.core.Transaction signedTransaction)

Check that the signedTransaction returned from the hardware wallet is essentially the same as the unsignedTransaction that was sent to it

Parameters:

unsignedTransaction - the unsignedTransaction sent to the hardware signing device

signedTransaction - the signed transaction returned from te hardware signing device

Returns:

true if the transactions are essentially the same, false otherwise
