<div dir="ltr">That's a valid concern, but I don't see the conflict here. In order to recover funds from a wallet conforming to BIPXX, you must have wallet software that handles BIPXX. Simply making BIPXX backwards compatible with previously created BIP44 or BIP43 purpose 0 wallets doesn't change this at all.</div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><br>Aaron Voisine</div><div>co-founder and CEO<br><a href="http://breadwallet.com" target="_blank">breadwallet</a></div></div></div></div></div></div></div></div>

</span>I see the advantage here. But there is a major problem here.<br>
<br>
We came up with BIP44 so a wallet can claim it is BIP44 compatible and<br>
you can be 100% sure that you can migrate accounts from one wallet<br>
implementation to another. This was not previously possible when a<br>
wallet claimed it is BIP32 compatible.<br>
<br>
Now we have a similar problem. When there is a BIP44 wallet, does it<br>
mean it supports segwit or not? For this reason I would like to see<br>
another BIPXX for segwit, so a wallet can claim it is BIP44, BIP44+BIPXX<br>
or BIPXX compatible and you'll know what other wallets are compatible<br>
with it.<br>
