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 start using the network and interact with Ethereum L2 Dapps. The skills here are also applicable to other layer two networks. We will illustrate this with an on-chain tic-tac-toe game running on the Scroll L2 network.

Preparation: Install Wallet

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

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). Any smart contract 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. This means that the Scroll L2 network will batch transactions and send them to the Goerli L1 network to "finalize" the transactions. While they still rely on the "security" of the Ethereum L1 network, scalability has been achieved because not every transaction needs to be published on the Ethereum 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 available, each with different features and methods of acquisition. You can choose one or combine multiple faucets to get enough ETH.

Step 3: Bridge ETH 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 use the bridging interface to complete this operation. Please note that this transaction will not be completed immediately and will take some time to transfer the ETH.

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

Once ETH is successfully transferred, you can try the on-chain Tic-Tac-Toe game. Connect your wallet and create a new game. Since this is a multiplayer game, you will need to add a friend's address or use a second wallet as an opponent.

After creating the game, select your game from the list and start playing on-chain Tic-Tac-Toe. 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

By following these steps, you can start exploring various applications on Scroll zkEVM and other L2 networks. As technology continues to evolve, these layer 2 solutions will bring more innovation and possibilities to the Ethereum ecosystem.
