Só pra constar, quem não sabe como assinar, aqui tem o tutorial feito pelo shorena ha muito anos atrás: https://bitcointalk.org/index.php?topic=990345.0

Neste tópico há tutorial para assinar:

   Bitcoin Core version v0.10.0
   Electrum v 1.9.8 (& 2.5.4)
   MultiBit v 0.5.18
   MultiBit HD v 0.1
   Blockchain.info
   Blockchain.info v2
   Mycelium 2.3.0 - 2.5.2 on Android Lollipop
   Coinbase
   Bither v.1.3.7.1
   Ledger Wallet Bitcoin v.1.10.1 (thx 2 JeremyB!)
   Trezor Wallet (thx 2 JeremyB!)

E para verificação:

   Blocktrail
   Brainwallet.org
   Chain Query Alpha
   coinig.com
   Trezor (thx 2 JeremyB!)

Entendi, acabei de fazer a minha com a Mycelium.

Alguém tem algum material sobre como funciona essa assinatura feita pelas Wallets?

Eu acho que no mastering bitcoin é capaz de ter algo. Acho que funciona de forma similar a assinatura em transações.
