lightning-txprepare -- Command to prepare to withdraw funds from the internal wallet ==================================================================================== SYNOPSIS -------- **txprepare** *outputs* [*feerate*] [*minconf*] [*utxos*] DESCRIPTION ----------- 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: see NOTES in lightning-feerates(7) for possible values. The default is *normal*. *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**. RETURN VALUE ------------ [comment]: # (GENERATE-FROM-SCHEMA-START) On success, an object is returned, containing: - **psbt** (string): the PSBT representing the unsigned transaction - **unsigned\_tx** (hex): the unsigned transaction - **txid** (txid): the transaction id of *unsigned\_tx*; you hand this to lightning-txsend(7) or lightning-txdiscard(7), as the inputs of this transaction are reserved. [comment]: # (GENERATE-FROM-SCHEMA-END) On failure, an error is reported and the 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.
