Scroll zkEVM Getting Started Guide

This article will introduce beginners to how to interact with L2 decentralized applications (Dapps), using Scroll zkEVM as an example. These skills are theoretically applicable to any layer two network. We will use an on-chain tic-tac-toe game running on the Scroll L2 network as an example.

Preparation: Install a Cryptocurrency Wallet

First, you need to install Metamask or a similar cryptocurrency wallet. If you have already installed it, you can skip this step. For new users, please install the appropriate version based on your device type.

Step 1: Configure the Test Network

Scroll zkEVM has currently launched its alpha testnet, which is a layer 2 network compatible with the Ethereum Virtual Machine (EVM). 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 Ethereum Goerli testnet.

You can follow the official guide to add the Scroll L2 network and Goerli testnet to your crypto wallet.

Step 2: Obtain test ETH

After configuring the network, you need to obtain some ETH from the Goerli testnet. There are several faucets to choose from:

1. A certain faucet website: provides 0.2 ETH each time, registration and login are required.
2. Another proof-of-work faucet: can provide more ETH, needs to keep the page open for "mining".
3. The third option: Requires Twitter login, get 0.1 ETH but it is slower.

You can choose one or use a combination of them. Make sure you have enough test ETH before proceeding to the next step.

Step 3: Cross-chain ETH to Scroll L2

Use the official cross-chain bridge to transfer some Goerli ETH to the address on the Scroll L2 testnet. This process will take some time to complete.

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

Connect your wallet to the game page and create a new game. This is a multiplayer game, and you need to add your friend's address or use a second wallet as an opponent. Select the created game to start experiencing the on-chain tic-tac-toe.

The game also has an interesting feature: if you make a mistake at any step or don't want to lose the game, you can reset the game at any time.

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

If you want to try other decentralized applications and games on Scroll, you can visit the relevant page for more information.

By following the steps above, you can start exploring decentralized applications on Scroll zkEVM and other layer two networks. This not only helps you understand emerging technologies but also allows you to experience the innovative applications brought by blockchain technology.
