The txprepare RPC command creates an unsigned transaction which
spends funds from Core Lightning's internal wallet to the outputs specified
in outputs.
The outputs is the array of output that include destination
and amount({destination: amount}). Its format is like:
[{address1: amount1}, {address2: amount2}]
or
[{address: all}].
It supports any number of confirmed outputs.
The destination of output is the address which can be of any Bitcoin accepted
type, including bech32.
The amount of output is the amount to be sent from the internal wallet
(expressed, as name suggests, in amount). The string all can be used to specify
all available funds. Otherwise, it is in amount 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 fund the transaction, as an array
of "txid:vout". These must be drawn from the node's available UTXO set.
txprepare is similar to the first part of a withdraw command, but
supports multiple outputs and uses outputs as parameter. The second part
is provided by txsend.
