The batcher receives the ability to sign and publish batches with change outputs.
Change is created when the clients choose fractional swap amounts from the input values to be swapped. Usually the change is sent back to client's addresses.
If change is provided to
ensurePresigned
,presign
andpublishPresigned
, it is expected to be placed within the passed[]sweep
.Each
sweep
optionally holds a pointer to a change output. Multiple sweeps holding the same change reference will produce a single change output in the batch transaction.
