Scroll zkEVM Introduction: Guide to Interacting with L2 Dapps

This article will introduce how to start using Scroll zkEVM and interact with Ethereum L2 Dapps. These skills can theoretically be applied to any layer two network. We will explain using an on-chain tic-tac-toe game running on the Scroll L2 network as an example.

Preparation: Install Wallet

If you haven't installed Metamask or a similar wallet yet, please complete the installation first. Metamask is a commonly used cryptocurrency wallet that can be used as a browser extension or mobile application.

Step 1: Configure the Test Network

Scroll zkEVM has currently launched its alpha testnet, which is a layer two network compatible with 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.

To set up the Scroll L2 network, please visit the official website and follow the instructions to add the network to your wallet. Additionally, if you haven't done so already, you also need to add the Goerli network to your wallet.

Step 2: Obtain Goerli Test ETH

After setting up the network, you need to obtain some ETH on the Goerli testnet. You can use the following faucets:

1. Faucet website A: Provides 0.2 ETH each time, registration and login are required.
2. Faucet website B: Based on the PoW mechanism, it can provide more ETH, but you need to keep the page open for "mining".
3. Certain faucet website C: Requires social media login, receives 0.1 ETH, but processing time is longer.

You can choose one or combine multiple faucets to get enough test ETH.

Step 3: Cross-chain ETH to Scroll L2

After obtaining Goerli test ETH, the next step is to cross-chain some ETH to the Scroll L2 testnet. Visit the official cross-chain interface and follow the on-screen instructions to transfer ETH to the Scroll L2 address. 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 the on-chain Tic Tac Toe game on Scroll L2. Visit the game webpage, connect your wallet, and create a new game. Since this is a multiplayer game, you will need to add another player's address, or you can use your second wallet as an opponent.

After creating the game, select your game from the list to get started. This game also has an interesting feature: if you make a mistake on a move or don’t want to lose the game, you can reset the game at any time.

Step 5 (Optional): Explore More Scroll L2 Dapps

If you want to experience more Dapps and games on Scroll, you can visit a certain webpage for more options.

By following the steps above, you have successfully gotten started with Scroll zkEVM and experienced Dapp interactions on the L2 network. These skills can help you better understand and engage with the rapidly evolving blockchain ecosystem.
