getmempooldescendants txid (verbose)

If txid is in the mempool, returns all in-mempool descendants.

Arguments:

“txid” (string, required) The transaction id (must be in mempool)
verbose (boolean, optional, default=false) True for a json object, false for array of transaction ids

Result (for verbose=false): [ (json array of strings) “transactionid” (string) The transaction id of an in-mempool descendant transaction ,… ]

Result (for verbose=true): { (json object) “transactionid” : { (json object) “size” : 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. “fee” : n, (numeric) transaction fee in BTC “modifiedfee” : n, (numeric) transaction fee with fee deltas used for mining priority “time” : n, (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) “descendantfees” : n, (numeric) modified fees (see above) 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) “ancestorfees” : n, (numeric) modified fees (see above) of in-mempool ancestors (including this one) “wtxid” : hash, (string) hash of serialized transaction, including witness data “depends” : [ (array) unconfirmed transactions used as inputs for this transaction “transactionid”, (string) parent transaction id … ] }, … }
