Beginner’s Guide: How to Use Scroll zkEVM

·

If you're new to Ethereum Layer 2 (L2) solutions and want to explore how to interact with decentralized applications (DApps) on scalable networks, you're in the right place. This guide walks you through the process of getting started with Scroll zkEVM, one of the most promising zk-rollup Layer 2 networks designed for Ethereum. By the end, you'll be able to connect your wallet, bridge assets, and interact with real DApps on Scroll — all while gaining transferable skills applicable across other EVM-compatible L2s.

Whether you're a developer, crypto enthusiast, or just curious about blockchain scalability, this step-by-step tutorial makes it easy to dive into the world of zero-knowledge rollups, Ethereum Layer 2, and on-chain gaming.


What Is Scroll zkEVM?

Scroll zkEVM is a zero-knowledge Ethereum Virtual Machine (zkEVM) Layer 2 scaling solution that aims to enhance Ethereum’s throughput while maintaining its security. It achieves this by processing transactions off-chain and submitting compressed proofs back to Ethereum Mainnet (Layer 1). This reduces gas fees and speeds up transaction finality without sacrificing decentralization.

As an EVM-equivalent network, Scroll supports the same smart contract code as Ethereum, making it easy for developers to port existing DApps. Currently in its alpha testnet phase, Scroll is live and ready for experimentation — perfect for beginners looking to get hands-on experience.


Step 1: Install a Web3 Wallet (e.g., MetaMask)

Before interacting with any blockchain application, you need a digital wallet. The most widely used option is MetaMask, a browser extension and mobile app that allows secure access to DApps.

To install:

Once installed, keep MetaMask running as we’ll use it throughout this guide.


Step 2: Add Scroll L2 and Goerli Testnet to Your Wallet

Scroll’s testnet currently connects to Ethereum’s Goerli test network (L1), meaning transactions are batched and proven on Goerli before final settlement.

Add Goerli Test Network

If you haven’t already:

  1. Open MetaMask.
  2. Click “Networks” > “Add Network.”
  3. Select “Goerli Test Network” from the dropdown, or manually input:

    • Network Name: Goerli
    • New RPC URL: https://goerli.infura.io/v3/ (use your Infura key or public endpoint)
    • Chain ID: 5
    • Currency Symbol: ETH

Add Scroll Alpha Testnet

Visit scroll.io/alpha and follow the instructions to add Scroll’s L2 network directly to MetaMask with one click. Alternatively, add manually using these details:

Now you’re set up on both L1 (Goerli) and L2 (Scroll).


Step 3: Get Goerli Test ETH from a Faucet

To perform transactions on Goerli, you’ll need testnet ETH. Here are reliable faucets:

  1. goerlifaucet.com – Provides 0.2 ETH per request; requires Alchemy account.
  2. goerli-faucet.pk910.de – A PoW-style faucet where you mine ETH in-browser; offers larger amounts over time.
  3. faucet.paradigm.xyz – Requires Twitter login; gives 0.1 ETH after a short wait.

Use one or combine multiple sources until you have at least 0.5 Goerli ETH in your wallet.

💡 Tip: These tokens have no real value — they’re only for testing purposes.

Step 4: Bridge ETH from Goerli to Scroll L2

With Goerli ETH in hand, it’s time to move funds to Scroll via the official bridge.

👉 Bridge assets securely across chains in minutes.

Steps:

  1. Go to the Scroll Bridge: scroll.io/alpha/bridge
  2. Connect your MetaMask wallet.
  3. Ensure you're on the Goerli network.
  4. Enter the amount of ETH to bridge (e.g., 0.1–0.3 ETH).
  5. Confirm the transaction in MetaMask.

Wait a few minutes for confirmation. Once complete, switch your wallet network to Scroll Alpha Testnet — you should now see your bridged ETH balance.

This process demonstrates how cross-chain interoperability works in zk-rollups: data is proven off-chain but secured by Ethereum.


Step 5: Play On-Chain TicTacToe on Scroll

Now let’s interact with a real DApp built on Scroll: an on-chain TicTacToe game created by the original author.

How to Play

  1. Visit: onchain-tictactoe.vercel.app
  2. Connect your wallet (ensure it's set to Scroll Alpha Testnet).
  3. Click “Create Game.”
  4. Enter another wallet address as the opponent — this could be a friend’s address or even your second wallet.
  5. Start playing! Each move writes directly to the blockchain.

Unique Features

This simple game illustrates how DApps can run efficiently and affordably on L2s like Scroll — with near-instant gameplay and minimal fees.

Frequently Asked Questions (FAQ)

Q: Is Scroll zkEVM safe to use?

Yes, during the alpha phase, Scroll is considered safe for testing. Transactions are secured by Ethereum via zero-knowledge proofs. However, avoid using real funds until mainnet launch.

Q: Why do I need Goerli ETH to use Scroll?

Scroll uses Goerli as its paired L1 testnet. Bridging requires gas on both L1 (for proof submission) and L2 (for execution), hence the need for test ETH on Goerli first.

Q: How long does bridging take?

Typically 5–15 minutes. Finalization depends on batch processing and proof generation times.

Q: Can I deploy my own smart contract on Scroll?

Yes! Since Scroll is EVM-equivalent, you can deploy using familiar tools like Hardhat or Foundry. Just update your RPC endpoint and verify contracts via Blockscout.

Q: What are zk-rollups, and why do they matter?

zk-Rollups bundle hundreds of off-chain transactions into a single proof verified on Ethereum. They offer scalability without compromising security — a critical advancement for mass blockchain adoption.

Q: When will Scroll launch mainnet?

While no official date has been confirmed beyond 2025, active testnet progress suggests mainnet could arrive soon. Stay tuned through official channels.


Final Thoughts

Getting started with Scroll zkEVM opens the door to understanding the future of scalable Ethereum. From setting up MetaMask and acquiring test tokens to bridging assets and playing interactive on-chain games, this guide equips you with foundational skills relevant across all modern Layer 2 ecosystems.
