They do require some work on the wallet side to support them&lt;p&gt;So how easy is it realistically? I hope it&amp;#x27;s not going to un-ergonomic like PGP where novices are sometimes seeing to be pasting their private key into e-mails and sending things in plaintext which should have been ciphertext, or otherwise leaking info.&lt;p&gt;I imagine you have to be really careful not to mess things up here.</text></comment>
