scantxoutset "action" ( [scanobjects,...] )
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
tr(<pubkey>) P2TR
tr(<pubkey>,{pk(<pubkey>)}) P2TR with single fallback pubkey in tapscript
rawtr(<pubkey>) P2TR with the specified key as output key rather than inner
wsh(and_v(v:pk(<pubkey>),after(2))) P2WSH miniscript with mandatory pubkey and a timelock
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.
Arguments:
1. action (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
2. scanobjects (json array, optional) 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 (when action=='start'; only returns after scan completes):
{ (json object)
"success" : true|false, (boolean) Whether the scan was completed
"txouts" : n, (numeric) The number of unspent transaction outputs scanned
"height" : n, (numeric) The current block height (index)
"bestblock" : "hex", (string) The hash of the block at the tip of the chain
"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
"coinbase" : true|false, (boolean) Whether this is a coinbase output
"height" : n (numeric) Height of the unspent transaction output
},
...
],
"total_amount" : n (numeric) The total amount of all found unspent outputs in BTC
}
Result (when action=='abort'):
true|false (boolean) True if scan will be aborted (not necessarily before this RPC returns), or false if there is no scan to abort
Result (when action=='status' and a scan is currently in progress):
{ (json object)
"progress" : n (numeric) Approximate percent complete
}
Result (when action=='status' and no scan is in progress - possibly already completed):
null (json null)
