title: Can I create a message to be signed instead of a transaction? with 0 Algo as fees?
body: <p>Can I create a message to be signed instead of a transaction?</p>
  <p>For example, I want a user to sign a message so I can confirm the address belongs to the user.</p>
  <p>I can do this using a 0 ALGO transaction with a note, but I was wondering if we have a tool just for signing messages, without any ALGO.</p>
