# What Am I Authorizing?

**What Are You Authorizing in This Step?**

Authorizing the Seamless Key to interact with MYX smart contracts. You are authorizing:1. **USDC Permit for Trading**:

* Allowing MYX to transfer USDC as collateral from your Master wallet for an amount specified by you when you call MYX contract to open a position.
* This is enabled by an **ERC20 Permit**

2\. **Enabling Your Seamless Key:**

• Granting the Seamless Key the ability to execute trades on your behalf through the MYX trading contract.\
**Why Is This Necessary?**

1. **To Enable Trading**:

• The Seamless Key acts as your delegated trader, eliminating the need for manual confirmations for every trade.

2. **To Maintain Security**:

• The authorization is limited to trading functions and does not provide direct access to your assets, which remain securely stored in your Master wallet.

3. **Limited USDC Authorization**:

• The authorization applies only to a specific amount for collateral and cannot be used for any other purpose.

**How Is Security Ensured?**

1\. **Non-Custodial Design**:

• The Seamless Key does not hold any assets, and all transactions must be approved via the MYX smart contract.

2.**Revocable Permissions**:

• You can revoke the Seamless Key’s authorization at any time from your Master wallet.

3.**Gas-Free Authorization**:

•The signing process is gas-free, with fees sponsored by MYX’s relayer, ensuring ease of use without compromising security.

By authorizing this interaction, you are empowering the Seamless Key to provide a fluid and secure trading experience, seamlessly bridging usability with decentralization.
