lightning-fundpsbt -- Command to populate PSBT inputs from the wallet
|
|
================================================================
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
**fundpsbt** *satoshi* *feerate* \[*minconf*\] \[*reserve*\]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
`fundpsbt` is a low-level RPC command which creates a PSBT using unreserved
|
|
inputs in the wallet, optionally reserving them as well.
|
|
|
|
*satoshi* is the minimum satoshi value of the output(s) needed (or the
|
|
string "all" meaning use all unreserved inputs). If a value, 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*.
|
|
|
|
You calculate the value by starting with the amount you want to pay
|
|
and adding the fee which will be needed to pay for the base of the
|
|
transaction plus that output, and any other outputs and inputs you
|
|
will add to the final transaction.
|
|
|
|
*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.
|
|
|
|
*reserve* is a boolean: if true (the default), then *reserveinputs* is
|
|
called (successfully, with *exclusive* true) on the returned PSBT.
|
|
|
|
RETURN VALUE
|
|
------------
|
|
|
|
On success, returns the *psbt* containing the inputs, and
|
|
*excess_msat* containing the amount above *satoshi* which is
|
|
available. This could be zero, or dust. If *satoshi* was "all",
|
|
then *excess_msat* is the entire amount once fees are subtracted
|
|
for the weights of the inputs.
|
|
|
|
If *reserve* was true, then a *reservations* array is returned,
|
|
exactly like *reserveinputs*.
|
|
|
|
On error the returned object will contain `code` and `message` properties,
|
|
with `code` being one of the following:
|
|
|
|
- -32602: If the given parameters are wrong.
|
|
- -1: Catchall nonspecific error.
|
|
- 301: Insufficient UTXOs to meet *satoshi* value.
