# FetchTransactionsFlow

`class FetchTransactionsFlow : FetchDataFlow<SignedTransaction, SignedTransaction>`

Given a set of tx hashes (IDs), either loads them from local disk or asks the remote peer to provide them.

A malicious response in which the data provided by the remote peer does not hash to the requested hash results in FetchDataFlow.DownloadedVsRequestedDataMismatch being thrown. If the remote peer doesnt have an entry, it results in a FetchDataFlow.HashNotFound exception. Note that returned transactions are not inserted into the database, because its up to the caller to actually verify the transactions are valid.
