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.
👉 Get started with secure wallet integration today.
To install:
- Visit metamask.io and download the version for your browser (Chrome, Firefox, etc.) or mobile device.
- Follow the setup instructions to create a new wallet.
- Securely back up your recovery phrase — never share it with anyone.
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:
- Open MetaMask.
- Click “Networks” > “Add Network.”
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:
- Network Name: Scroll Alpha Testnet
- RPC URL:
https://alpha-rpc.scroll.io/l2 - Chain ID: 534353
- Currency Symbol: ETH
- Block Explorer: https://blockscout.scroll.io
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:
- goerlifaucet.com – Provides 0.2 ETH per request; requires Alchemy account.
- goerli-faucet.pk910.de – A PoW-style faucet where you mine ETH in-browser; offers larger amounts over time.
- 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:
- Go to the Scroll Bridge: scroll.io/alpha/bridge
- Connect your MetaMask wallet.
- Ensure you're on the Goerli network.
- Enter the amount of ETH to bridge (e.g., 0.1–0.3 ETH).
- 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
- Visit: onchain-tictactoe.vercel.app
- Connect your wallet (ensure it's set to Scroll Alpha Testnet).
- Click “Create Game.”
- Enter another wallet address as the opponent — this could be a friend’s address or even your second wallet.
- Start playing! Each move writes directly to the blockchain.
Unique Features
- Fully on-chain logic: No backend servers — every action is verified on-chain.
- Game reset option: Made a mistake? Reset the game anytime without losing funds.
- Open-source code: Check out the project on GitHub to learn how it was built using Solidity and Hardhat.
This simple game illustrates how DApps can run efficiently and affordably on L2s like Scroll — with near-instant gameplay and minimal fees.
Step 6 (Optional): Explore More DApps on Scroll
Want more? Scroll is already hosting various experimental DApps and developer projects.
Check out:
- ethdenver.scroll.systems – A showcase of DApps built during EthDenver hackathons.
- Scroll’s official DApp gallery (coming soon) for emerging tools in DeFi, NFTs, and gaming.
Exploring different apps helps you understand how developers are leveraging low-cost transactions and high throughput on zkEVMs.
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.
