  "ancestorcount" : n,                  (numeric) number of in-mempool ancestor transactions (including this one)
  "ancestorsize" : n,                   (numeric) virtual transaction size of in-mempool ancestors (including this one)
  "wtxid" : "hex",                      (string) hash of serialized transaction, including witness data
  "fees" : {                            (json object)
    "base" : n,                         (numeric) transaction fee, denominated in BTC
    "modified" : n,                     (numeric) transaction fee with fee deltas used for mining priority, denominated in BTC
    "ancestor" : n,                     (numeric) transaction fees of in-mempool ancestors (including this one) with fee deltas used for mining priority, denominated in BTC
    "descendant" : n                    (numeric) transaction fees of in-mempool descendants (including this one) with fee deltas used for mining priority, denominated in BTC
  },
  "depends" : [                         (json array) unconfirmed transactions used as inputs for this transaction
    "hex",                              (string) parent transaction id
    ...
  ],
  "spentby" : [                         (json array) unconfirmed transactions spending outputs from this transaction
    "hex",                              (string) child transaction id
    ...
  ],
  "bip125-replaceable" : true|false,    (boolean) Whether this transaction signals BIP125 replaceability or has an unconfirmed ancestor signaling BIP125 replaceability.
                                        
  "unbroadcast" : true|false            (boolean) Whether this transaction is currently unbroadcast (initial broadcast not yet acknowledged by any peers)
