# # Arc Testnet Complete Interaction Guide

**Step 1: Send a GM Message**
Open the interaction page, connect your wallet, and switch to the Arc testnet. Find the "Send GM" button and click it, then confirm in the wallet popup. This is the most basic on-chain interaction.

**Step 2: Deploy Smart Contracts**
Stay on the same page and keep your wallet connected. You'll see three deployment options:
- Simple contract deployment
- Token contract deployment
- NFT contract deployment

Click each one in turn; every time, a wallet confirmation window will pop up—just authorize it. These three contracts cover the core interaction scenarios of the testnet. Once you complete this set of steps, you’ll have a thorough grasp of the Arc network.

The operations are not complicated—the key is to get familiar with contract interaction logic in the testnet environment.
