# Verify Signature

Verify if the signature is valid

## Setup

First of all, you will need the signature itself from the sign message action, so make sure you save it somewhere in the database.

### State - Signature is Valid

The state is of Yes/No type.

## Demo

To try this feature on our demo page, you need to add a pair, load all pairs and sign a message first, then a popup will be shown with the signature, in this popup you can verify the signature.

It is easier than it sounds :) \
