# Ondo

#### Prerequisites

* Have an account on **Ondo Perps** ([app.ondoperps.xyz](https://app.ondoperps.xyz)) created with the wallet you intend to use.
* **An EVM-compatible wallet** supported by Tread's wallet connector (e.g. MetaMask, Rabby, WalletConnect-compatible wallets).
* Ensure your Ondo account is funded before connecting so you can begin trading.

#### Linking Your Ondo Account

**Open Up the** [**Key Management**](https://app.tread.fi/key_management) **menu on tread.fi**

* This can be accessed by clicking on the wallet icon on the top right corner on app.tread.fi after you have logged in.

**Link Exchange API Key**

* Click **Connect Ondo**
* Set your desired name for this exchange account.
* Connect the same wallet you used to create your Ondo account.
* You will be prompted to **sign an Ondo login challenge**. This is a standard wallet signature (Sign-In with Ethereum) — it does **not** authorize any transaction or transfer of funds.
* After you sign, Tread automatically creates a **trade-only API key** on Ondo and links it to your account.
* Click Submit and proceed with wallet signing and confirmation.
* You can revoke this key at any time from your account on [app.ondoperps.xyz](https://app.ondoperps.xyz).
