getrawmempool

getrawmempool ( verbose )

Returns all transaction ids in memory pool as a json array of string transaction ids.

Hint: use getmempoolentry to fetch a specific transaction from the mempool.

Argument #1 - verbose

Type: boolean, optional, default=false

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

Result (for verbose = false)

[                     (json array of string)
  "transactionid"     (string) The transaction id
  ,...
]

Result (for verbose = true)
