The /* a the top is just not obligatory, however changesthe which means, and dropping it’s most likely not what you need.
Conceptually, in case you have a m/48'/0'/0'/2' pockets, it means the keys your pockets makes use of are derived as (with m some grasp key):
m/48'/0'/0'/2'/0m/48'/0'/0'/2'/1m/48'/0'/0'/2'/2- …
In different phrases, it denotes a key chain consisting of a number of keys, every with their very own derivation path.
The way in which to jot down that as a descriptor is as xpubM.../48'/0'/0'/2'/*, the place xpubM... is the precise xpub equivalent to the grasp key m. In apply, you’ll precompute the xpub for simply the derivation half m/48'/0'/0'/2' and simply use xpub.../*.
You can simply write “xpub…”, however then you’ve gotten a pockets consisting of simply the one key equivalent to m/48'/0'/0'/2' itself, somewhat than the addresses derived from that key. Equally, you can simply use xpub.../0, however then you’ve gotten a pockets consisting of simply the one key correspondong to m/48'/0'/0'/2'/0, which might be simply the primary key you need somewhat than all of them.
