# How to sign data with dapps?

Since **My Wallet 3.8**, dapps connected via **TON Connect** can ask you to **securely sign data**—messages, files, smart contracts, and other data—directly from My Wallet. My Wallet was one of the **first TON wallets** to support this capability.

## How it works

{% stepper %}
{% step %}
A connected dapp requests a **signature** for a message, file, or piece of data (instead of a transaction).
{% endstep %}

{% step %}
My Wallet shows you **what you're signing**, so you can review it before confirming.
{% endstep %}

{% step %}
Confirm to **sign**, or close the prompt to decline.
{% endstep %}
{% endstepper %}

{% hint style="warning" %}
**Review every signature request carefully.** Only sign data from **dapps you trust**—a signature can authorize actions just like a transaction can.
{% endhint %}
