bitcoin core – How to realize dependent transaction seats in the Mempool?

getrawmempool

getrawmempool(true)

Returns all transaction aids in the memory pool as a variety of string transaction offers. If we use verbatim as ‘true’ it returns more than just transactional aids and one of the consequences is ‘depend’.

"depends" : [(json array) unconfirmed transactions used as inputs for this transaction "hex",(string) parent transaction id]

Example:
