# Using ONZA App

## 🔌 Exchanges & API Connection

ONZA allows users to connect supported exchanges using API keys.

This enables the platform to interact with user accounts in a **non-custodial manner**, meaning:

* Users retain full control of their funds
* ONZA does not hold or manage assets

#### Key Principles

* Only **trading permissions** are required
* **Withdrawal access should never be enabled**
* API connections are user-controlled and can be removed at any time

### Step 1 — Open Exchanges in ONZA

* Open the ONZA App
* Go to **Profile**
* Tap **Exchanges**
* Tap the **“+” (Add)** button
