Scroll zkEVM Beginner's Guide

This article will introduce beginners to how to interact with L2 Dapps, using Scroll zkEVM as an example, explaining how to get started with the Ethereum L2 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

If you have already installed a cryptocurrency wallet, you can skip this step. Otherwise, please install the appropriate cryptocurrency wallet for your device.

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

Scroll zkEVM has currently launched the alpha testnet, which is a layer two network compatible with EVM. This means that smart contracts written for the Ethereum network can be directly deployed on Scroll zkEVM. The Scroll L2 alpha testnet is currently connected to the Goerli testnet of Ethereum L1.

You can add the Scroll L2 network to your crypto wallet according to the instructions on the official website. At the same time, if you haven't added it yet, please also add the Goerli network to your wallet.

Step 2: Obtain Goerli Test ETH

After setting up the network, you need to get some Goerli ETH from a faucet. There are several faucet options available:

1. A faucet that provides 0.2 ETH each time, requires registration and login to obtain tokens.
2. A faucet based on proof of work that can provide more ETH, but requires keeping the page open and "mining".
3. A faucet that requires Twitter login can earn 0.1 ETH, but the process is relatively slow.

You can choose one or combine multiple faucets.

Step 3: Bridge ETH from Goerli to Scroll L2

After obtaining enough Goerli ETH, the next step is to bridge a portion of it to the Scroll L2 testnet. You can complete this step using the official bridging interface. Follow the instructions on the page to transfer ETH to your address on the Scroll L2 testnet.

Please note that this process will take some time to complete.

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

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

After creating the game, select your game from the list and start playing. This 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 other Dapps on Scroll L2

If you want to experience more Dapps and games on Scroll, you can visit the official Dapps list page.

By following these steps, you can start exploring and using various Dapps on Scroll zkEVM. These experiences can also help you better understand and use other L2 networks.
