and 1
are used for the external and internal chains, respectively. The external chain is used for addresses that are meant to be visible outside of the wallet context (i.e., for receiving payments). The internal chain is used for addresses which should remain private within the wallet context; this chain is used to store change returned from broadcast transactions. Public derivation is used at this level.0
