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 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 the 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*. **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**. *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 *unsigned\_tx* and *txid* will be returned. You need to hand *txid* to **txsend** or **txdiscard**, as the inputs of this transaction are reserved until then, or until the daemon restarts. *unsigned\_tx* represents the raw bitcoin transaction (not yet signed) and *txid* represent the bitcoin transaction id. 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.
