Scroll zkEVM Getting Started Guide

This article will introduce beginners on how to interact with Layer 2 network (L2) Dapps. We will take Scroll zkEVM as an example to explain how to start using this platform and interact with Ethereum L2 Dapps. The skills learned in this article can theoretically be applied to other Layer 2 networks. To illustrate better, 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 based on your browser or mobile device.

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 deployed on Scroll zkEVM using the same tools. The Scroll L2 alpha testnet is currently connected to the Goerli test network of Ethereum L1. The Scroll L2 network batches transactions and sends them to the Goerli L1 network to "finalize" the transactions. Therefore, it still relies on the security of the Ethereum L1 network, but achieves scalability by not requiring every transaction to be posted on the Ethereum network.

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

Step 2: Obtain Goerli Test ETH

After setting up the network, you need to get some Goerli ETH from a faucet. There are multiple faucets to choose from, and each faucet has different amounts of ETH available and different methods of obtaining it. You can choose one or combine several 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 a portion of it to the Scroll L2 testnet. You can use the official bridging interface 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 4: Experience the On-Chain Tic-Tac-Toe Game

Once your ETH is successfully transferred to Scroll L2, you can start experiencing on-chain games. 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, and you can also use your other wallet address as the second player.

After creating the game, select your game from the list, and then 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 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 more Dapps and games on Scroll, you can check the official Dapps list provided. This will help you gain a more comprehensive understanding of the current status and potential of the Scroll L2 ecosystem.

By following the steps above, you can start exploring Scroll zkEVM and the applications running on it. As you gain a deeper understanding of this platform, you will discover more interesting use cases and opportunities. Come and experience the charm of Scroll L2 for yourself!
