@NotATether:
I would put the change by itself in its own LN channel
So u mean like send the certain change funds with coin control to an established LN over swapping for example with integrated swapping in electrum.
@LoyceV:
I'm not sure what you mean.
I mean to create multi exchanges with an none KYC services like swapping to obfuscate the change funds.
Avoid change is only possible with donation or an exact payment where in and out txes are equal or
