Scroll zkEVM Beginner's Guide

This article will introduce beginners on how to interact with L2 Dapps, taking Scroll zkEVM as an example. The skills introduced here can theoretically be applied to other Layer 2 networks. 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 a compatible cryptocurrency wallet, such as Metamask.

Step 1: Configure Scroll L2 Testnet and Goerli Testnet

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 Goerli testnet of Ethereum L1.

You can visit the official Scroll website and follow the instructions to add the Scroll L2 network and the Goerli network to your crypto wallet.

Step 2: Obtain Goerli Test ETH

After configuring the network, you need to obtain some Goerli ETH from a faucet. There are several faucets to choose from, such as Alchemy's faucet, PoW faucet, etc. You can choose one or more of them 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 operation. 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 Four: Experience the On-chain Tic-Tac-Toe Game

Once your ETH is successfully transferred to Scroll L2, you can start experiencing the on-chain Tic Tac Toe game. Connect your wallet to the game page and create a new game. Since this is a multiplayer game, you need to add the address of another player. You can also use your own second wallet address as an opponent.

After creating a game, select your game from the game list, and you can start playing tic-tac-toe on the chain. This game also has an interesting feature: if you make a wrong move at any step, or if you 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 try more Dapps and games on Scroll, you can check out the list of Dapps provided by Scroll, where there are more interesting applications waiting for you to explore.

With this beginner's guide, you should be able to start using Scroll zkEVM and interact with L2 Dapps. As you become more familiar with this ecosystem, you will discover more interesting applications and opportunities.
