Scroll zkEVM Introduction Guide

This article will introduce beginners to how to interact with L2 Dapps. We will take Scroll zkEVM as an example to explore how to get started with this network and interact with Ethereum L2 Dapps. The skills learned in this guide can theoretically be applied to any other Layer 2 network. To better illustrate, we will use an on-chain tic-tac-toe Dapp running on the Scroll L2 network as an example.

Preparations: Install Wallet

If you have already installed a wallet similar to Metamask, you can skip this step. Otherwise, please install the appropriate wallet according to your device and browser type.

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 EVM (Ethereum Virtual Machine). This means that smart contracts written for the Ethereum network can be deployed on Scroll zkEVM using the same tools. The Scroll L2 alpha testnet is currently connected to the Goerli test network on Ethereum L1. The Scroll L2 network batches transactions and sends them to the Goerli L1 network for final confirmation, thereby achieving scalability while maintaining the security of the Ethereum L1 network.

You can follow the instructions to add the Scroll L2 network and the Goerli network to your wallet.

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 different methods of obtaining and quantity limits. You can choose one or more faucets to get enough ETH.

Step 3: "Bridge" ETH from Goerli to Scroll L2

After obtaining enough Goerli ETH, the next step is to bridge some ETH to the Scroll L2 testnet. You can complete this step using the bridging interface. Please note that this transaction may take some time to complete.

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

Once ETH is successfully transferred to Scroll L2, you can start enjoying the on-chain tic-tac-toe game. Connect your wallet and create a new game. Since this is a multiplayer game, you need to add your friend's address or use a second wallet as an opponent.

After creating the game, select your game from the list to 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 try other Dapps and games on Scroll, you can check out more related resources.

With this beginner's guide, you should be able to start exploring Dapps on Scroll zkEVM and other L2 networks. As more innovative applications emerge, the L2 ecosystem will provide users with a richer experience and more possibilities.
