getmempoolentry "txid"

Returns mempool data for given transaction

Arguments:
1. txid    (string, required) The transaction id (must be in mempool)

Result:
{                                (json object)
  "vsize" : n,                   (numeric) (DEPRECATED) Was previously erroneously described as the BIP 141 vsize, but is actually sigops-adjusted vsize.
                                 Use vsize_bip141 to actually get that behavior or switch to the explicit vsize_adjusted for retained behavior.
  "vsize_bip141" : n,            (numeric) Virtual transaction size as defined in BIP 141.
                                 This is different from actual serialized size for witness transactions as witness data is discounted.
  "vsize_adjusted" : n,          (numeric) Maximum of sigop-adjusted size (-bytespersigop) and virtual transaction size as defined in BIP 141.
  "weight" : n,                  (numeric) transaction weight as defined in BIP 141.
  "time" : xxx,                  (numeric) local time transaction entered pool in seconds since 1 Jan 1970 GMT
  "height" : n,                  (numeric) block height when transaction entered pool
  "descendantcount" : n,         (numeric) number of in-mempool descendant transactions (including this one)
  "descendantsize" : n,          (numeric) virtual transaction size of in-mempool descendants (including this one)
  "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)
  "chunkweight" : n,             (numeric) sigops-adjusted weight (as defined in BIP 141 and modified by '-bytespersigop') of this transaction's chunk
  "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
    "chunk" : n                  (numeric) transaction fees of chunk, 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
    ...
  ],
  "unbroadcast" : true|false     (boolean) Whether this transaction is currently unbroadcast (initial broadcast not yet acknowledged by any peers)
}
