#### 3. Asset Management: Claim and Encrypt

Before your Agent can operate, it requires gas (Sepolia ETH) and payment tokens (TestUSDC).

**Step A: Faucet**

* **Sepolia ETH**: If your wallet lacks Sepolia ETH for gas fees, please obtain some from a standard Sepolia faucet.
* **TestUSDC:** Locate the asset panel and click Claim TestUSDC. This asset will serve as the underlying capital for your Agent's payments.

**Step B: Encrypt Assets (Claim ConfUSDC) To utilize the privacy features of x402z, you must convert public ERC-20 tokens into Confidential Tokens.**

1. Refresh your asset balance to see the claimed TestUSDC.
2. Input the amount of TestUSDC you wish to encrypt (Recommendation: Minimum 10 USDC).
3. Click Encrypt to Wrap ConfUSDC.

> Note: This process utilizes Fully Homomorphic Encryption (FHE) standards to ensure your balance remains private on-chain.

* **Privacy Warning:** Unwrapping assets will expose the specific amount on the public blockchain.
* **Confirmation:** Click Confirm Decrypt and sign the transaction. Please ensure you have sufficient Sepolia ETH to cover the gas fees.
