small nit with 3. It seems to me that the wallet would perform initial discovery on m/44 and m/49, and then would find transactions at one or the other, so it can then record the type somewhere and from then on need only monitor one branch. Still, I agree it is ugly, makes initial discovery up to 2x slower, etc. > *- XPUB Derivation* > This is something not addressed in the BIP yet. > > 1.
