+   - System will generate a new agent wallet automatically
+   - **Save the agent wallet address** (starts with `0x`)
+   - **Save the agent private key** (shown only once!)
+
+4. **Agent Wallet Details**:
+   - Main Wallet: Your connected wallet (holds funds)

+   - Private Key: Only needed for NOFX configuration
+
+5. **Fund Your Agent** (Optional):
+   - Transfer USDC from main wallet to agent wallet
+   - Or keep funds in main wallet (agent can trade from it)
+
+6. **Save Credentials for NOFX**:
+   - Main Wallet Address: `0xYourMainWalletAddress` (with `0x`)
+   - Agent Private Key: `YourAgentPrivateKeyWithout0x` (remove `0x` prefix)
