# How to sign a message using your wallet?

Signing a message with your web 3 wallet has a number of use-cases. The most notably of these is to verify your ownership of the address used.

The following instructions will help guide you through the process of signing a message in order to verify that you are the address owner. <br>

For this tutorial we will be using Polygonscan and our Rainbow wallet. We will be signing a message on the Polygon Network.  <br>

The process is identical with Metamask, Trust, and any of the other leading Web3 wallets.&#x20;
