lightning-multiwithdraw -- Command for withdrawing to multiple addresses
|
||
========================================================================
|
||
|
||
SYNOPSIS
|
||
--------
|
||
|
||
**multiwithdraw** *outputs* \[*feerate*\] \[*minconf*\] \[*utxos*\]
|
||
|
||
DESCRIPTION
|
||
-----------
|
||
|
||
The **multiwithdraw** RPC command sends funds from c-lightning’s internal
|
||
wallet to the addresses specified in *outputs*,
|
||
which is an array containing objects of the form `{address: amount}`.
|
||
The `amount` may be the string *"all"*, indicating that all onchain funds
|
||
be sent to the specified address.
|
||
Otherwise, it is in satoshi precision;
|
||
it can be
|
||
a whole number,
|
||
a whole number ending in *sat*,
|
||
a whole number ending in *000msat*,
|
||
or a number with 1 to 8 decimal places ending in *btc*.
|
||
|
||
*feerate* is an optional feerate to use. It can be one of the strings
|
||
*urgent* (aim for next block), *normal* (next 4 blocks or so) or *slow*
|
||
(next 100 blocks or so) to use lightningd’s internal estimates: *normal*
|
||
is the default.
|
||
|
||
Otherwise, *feerate* is a number, with an optional suffix: *perkw* means
|
||
the number is interpreted as satoshi-per-kilosipa (weight), and *perkb*
|
||
means it is interpreted bitcoind-style as satoshi-per-kilobyte. Omitting
|
||
the suffix is equivalent to *perkb*.
|
||
|
||
*minconf* specifies the minimum number of confirmations that used
|
||
outputs should have. Default is 1.
|
||
|
||
*utxos* specifies the utxos to be used to be withdrawn from, as an array
|
||
of "txid:vout". These must be drawn from the node's available UTXO set.
|
||
|
||
RETURN VALUE
|
||
------------
|
||
|
||
On success, an object with attributes *tx* and *txid* will be returned.
|
||
|
||
*tx* represents the raw bitcoin, fully signed, transaction and *txid*
|
||
represent the bitcoin transaction id.
|
||
|
||
On failure, an error is reported and the withdrawal transaction is not
|
||
created.
|
||
|
||
The following error codes may occur:
|
||
- -1: Catchall nonspecific error.
|
||
- 301: There are not enough funds in the internal wallet (including
|
||
fees) to create the transaction.
|
||
- 302: The dust limit is not met.
