lightning-unreserveinputs – Release reserved UTXOs


unreserveinputs psbt


The unreserveinputs RPC command releases (or reduces reservation) on UTXOs which were previously marked as reserved, generally by lightning-reserveinputs(7).

The inputs to unreserve are the inputs specified in the passed-in psbt.


On success, an reservations array is returned, with an entry for each input which was reserved:

  • txid is the input transaction id.
  • vout is the input index.
  • was_reserved indicates whether the input was already reserved (generally true)
  • reserved indicates that the input is now reserved (may still be true, if it was previously reserved for a long time).
  • reserved_to_block (if reserved is still true) indicates what blockheight the reservation will expire.

On failure, an error is reported and no UTXOs are unreserved.

The following error codes may occur:

  • -32602: Invalid parameter, i.e. an unparseable PSBT.
