When verbose is false (the default), result is an array of transaction ids for in-mempool descendant transactions.

result

string

The transaction id of an in-mempool ancestor transaction

(for verbose = true)

object

When verbose is true, result is a JSON object mapping each descendant transaction id to its detailed transaction data.

transactionid

object

The transaction id

vsize

integer

The virtual transaction size as defined in BIP 141. This is different from actual serialized size for witness transactions as witness data is discounted

weight

integer

time

integer

height

integer

The block height when the transaction entered pool

descendantcount

integer

The number of in-mempool descendant transactions (including this one)

descendantsize

integer

The virtual transaction size of in-mempool descendants (including this one)

ancestorcount

integer

The number of in-mempool ancestor transactions (including this one)

ancestorsize

integer

The virtual transaction size of in-mempool ancestors (including this one)

wtxid

string

The hash of serialized transaction, including witness data

fees

object

A JSON array containing information about the transaction fee paid by the transaction

base

number

The transaction fee in BTC

modified

number

descendant

number

The modified fees of in-mempool descendants (including this one) in BTC

depends

array

Unconfirmed transactions used as inputs for this transaction

hex

string

The parent transaction id

spentby

array

Unconfirmed transactions spending outputs from this transaction

hex

string

The child transaction id
