scantxoutset

scantxoutset "action" ( [scanobjects,...] )

EXPERIMENTAL warning: this call may be removed or changed in future releases.

Scans the unspent transaction output set for entries that match certain output descriptors.

Examples of output descriptors are:

addr(<address>) Outputs whose scriptPubKey corresponds to the specified address (does not include P2PK) raw(<hex script>) Outputs whose scriptPubKey equals the specified hex scripts combo(<pubkey>) P2PK, P2PKH, P2WPKH, and P2SH-P2WPKH outputs for the given pubkey pkh(<pubkey>) P2PKH outputs for the given pubkey sh(multi(<n>,<pubkey>,<pubkey>,…)) P2SH-multisig outputs for the given threshold and pubkeys

In the above, <pubkey> either refers to a fixed public key in hexadecimal notation, or to an xpub/xprv optionally followed by one or more path elements separated by “/”, and optionally ending in “/*” (unhardened), or “/*’” or “/*h” (hardened) to specify all unhardened or hardened child keys.

In the latter case, a range needs to be specified by below if different from 1000.

For more information on output descriptors, see the documentation in the doc/descriptors.md file.

Argument #1 - action

Type: string, required

The action to execute

“start” for starting a scan “abort” for aborting the current scan (returns true when abort was successful) “status” for progress report (in %) of the current scan

Argument #2 - scanobjects

Type: json array

Array of scan objects. Required for “start” action

Every scan object is either a string descriptor or an object:

[
  "descriptor",             (string) An output descriptor
  {                         (json object) An object with output descriptor and metadata
    "desc": "str",          (string, required) An output descriptor
    "range": n or [n,n],    (numeric or array, optional, default=1000) The range of HD chain indexes to explore (either end or [begin,end])
  },
  ...
]

Result

  "unspents" : [                 (json array)
    {                            (json object)
      "txid" : "hex",            (string) The transaction id
      "vout" : n,                (numeric) The vout value
      "scriptPubKey" : "hex",    (string) The script key
      "desc" : "str",            (string) A specialized descriptor for the matched scriptPubKey
      "amount" : n,              (numeric) The total amount in BTC of the unspent output
      "height" : n               (numeric) Height of the unspent transaction output
    },
    ...
  ],
  "total_amount" : n             (numeric) The total amount of all found unspent outputs in BTC
