Scroll zkEVM Introduction Guide

This article will introduce beginners to how to interact with L2 Dapps, using Scroll zkEVM as an example. We will demonstrate the entire process using an on-chain tic-tac-toe game running on the Scroll L2 network. The skills learned in this guide are also applicable to other Layer 2 networks.

Preparation Work

First, you need to install Metamask or a similar cryptocurrency wallet. If you have already installed Metamask, you can skip this step.

Step 1: Set up the Scroll L2 Testnet and Goerli Testnet

Scroll zkEVM has currently launched its alpha testnet, which is a Layer 2 network compatible with the EVM (Ethereum Virtual Machine). This means that smart contracts written for Ethereum can be directly deployed on Scroll zkEVM. The Scroll L2 alpha testnet is currently connected to the Goerli testnet on Ethereum L1.

To set up the Scroll L2 network, please visit the official Scroll website and follow the instructions to add the network to your Metamask. Additionally, you will need to add the Goerli network to Metamask (if it hasn't been added yet).

Step 2: Obtain Goerli Test ETH

After setting up the network, you need to obtain some Goerli ETH from a faucet. There are multiple faucets to choose from, each with slightly different methods and amounts for obtaining ETH. You can choose one or more faucets to get enough test ETH.

Step 3: Bridge ETH from Goerli to Scroll L2

After obtaining Goerli ETH, the next step is to bridge some ETH to the Scroll L2 testnet. You can use the bridging interface provided by Scroll to complete this step. Follow the instructions on the page to transfer ETH to your address on the Scroll L2 testnet. Please note that this process may take some time to complete.

Step 4: Experience the On-Chain Tic-Tac-Toe Game

You can now try playing on-chain Tic Tac Toe on Scroll L2. Visit the game webpage, connect your wallet, and create a new game. This is a multiplayer game, and you need to add a friend's address or use a second wallet as your opponent.

After creating the game, select your game from the game list and start playing. This game also has an interesting feature: if you make a mistake at any step or do not want to lose the game, you can reset the game at any time.

Step 5 (Optional): Explore other Dapps on Scroll L2

If you want to experience more Dapps and games on Scroll, you can visit the Dapps list page provided by the official Scroll, where more interesting applications await your exploration.

Through this simple guide, you have learned how to perform basic operations and interactions on L2 networks like Scroll zkEVM. These skills will help you better understand and participate in the Web3 ecosystem.
