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

by

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:

"2004b140d4b4eb1048cdb7def895a211c279711e47cc402c64f91f1c0d20f0dc": {

      "descendant": 0.00000446
    },
    "vsize": 142,
