getmempooldescendants¶

getmempooldescendants "txid" ( verbose )

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

Argument #1 - txid¶

Type: string, required

The transaction id (must be in mempool)

Argument #2 - verbose¶

Type: boolean, optional, default=false

True for a json object, false for array of transaction ids

Result (for verbose = false)¶

[           (json array)
  "hex",    (string) The transaction id of an in-mempool descendant transaction
  ...
]

Result (for verbose = true)¶
