lightning-reserveinputs -- Construct a transaction and reserve the UTXOs it spends ================================================================================== SYNOPSIS -------- **reserveinputs** *outputs* \[*feerate*\] \[*minconf*\] \[*utxos*\] DESCRIPTION ----------- The **reserveinputs** RPC command creates an unsigned PSBT which spends funds from c-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 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 reserved UTXOs 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. RETURN VALUE ------------ On success, an object with attributes *psbt* and *feerate_per_kw* will be returned. The inputs of the *psbt* have been marked as reserved in the internal wallet. On failure, an error is reported and no UTXOs are reserved. 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.
