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.

4. Execute Agent Tasks

  1. Scroll down to the Agent control panel.

  2. Click Start Agent to initiate the automated testing sequence.

Beta Warning: As this is a testnet environment, you may experience intermittent service or network latency. If the Agent fails to start, please retry after a few moments.
