Provisional in-wallet help
This window allows you to view the unused payment destinations that the given account will use next. In some cases these will be standard Bitcoin addresses, and in other cases where the script type has no address form, the BIP276 standard will be used to present them.
The destinations listed here are not reserved. If you take them and use them elsewhere, there is no guarantee that ElectrumSV won't also proceed to use them in the course of it's normal wallet usage on your behalf.
