+===Extended Key Version===

+When serializing extended keys, this scheme uses alternate version bytes. Extended public keys use <code>0x049d7cb2</code> to produce a "ypub" prefix, and private keys use <code>0x049d7878</code> to produce a "yprv" prefix. Testnet uses <code>0x044a5262</code> "upub" and <code>0x044a4e28</code> "uprv."
