# Security

The OPZ app prioritizes the safety of your digital assets and interactions in Web3. We've added multiple layers of advanced security features to our app. That makes our app powerful, safe, and easy to use.

### Security Features:

#### **1. Token Safety, Address Verification, and dApp Security:**

Partnering with GoPlus Security, OPZ has added important security features to protect your transactions:

* **Token Security API:** This tool automatically checks tokens for any risks and informs you about potential issues.
* **Malicious Address API:** It scans the addresses you're sending assets to, warning you if there's anything suspicious.
* **dApp Security API:** When you're using dApps, this feature automatically checks them for safety and alerts you about any risks.

**2. MPC-2FA Signing:**

For added security, OPZ offers an optional Two-Factor Authentication (2FA) feature for MPC transactions:

* **Extra Safety for Your Transactions:** This feature adds a second check whenever you make a transaction, ensuring that only you can authorize these actions.

**3. Anti-Zero Transfer:**

To combat the rising issue of zero transfer phishing scams, OPZ has developed the Anti-Zero Transfer feature:

* **Blocking Phishing Attempts:** This setting stops zero-value transactions from showing up in your history, which is often used in scams. It helps keep your transaction history clean and safe.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://whitepaper.opz.io/opz-app/security.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
