This guide introduces beginners to interacting with Layer 2 (L2) decentralized applications (Dapps) on Scroll zkEVM—an Ethereum-compatible zero-knowledge rollup solution. By following these steps, you'll learn transferable skills for navigating any L2 ecosystem.
Prerequisites: Set Up MetaMask
If you already have MetaMask installed, skip this step. Otherwise:
- Visit MetaMask's official download page.
- Install the version compatible with your browser or mobile device.

Step 1: Configure Scroll L2 Testnet and Goerli Testnet
Scroll zkEVM's alpha testnet operates as an EVM-compatible L2 network, batch-processing transactions via Ethereum's Goerli testnet for finality.
To add both networks to MetaMask:
- Navigate to Scroll's alpha portal.
Follow the instructions to import:
- Scroll zkEVM Testnet
- Goerli Testnet (if not already added)
Step 2: Acquire Goerli Test ETH
Obtain test ETH from these faucets (combine for larger amounts):
| Faucet | Amount | Requirements |
|---|---|---|
| Alchemy Goerli Faucet | 0.2 ETH | Alchemy account |
| PoW Goerli Faucet | Variable | Browser mining |
| Paradigm Faucet | 0.1 ETH | Twitter login |
Pro Tip: The PoW faucet yields more ETH with extended usage.
Step 3: Bridge ETH to Scroll L2
Transfer Goerli ETH to Scroll L2:
- Visit Scroll's bridge interface.
- Follow the on-screen instructions.
- Wait for confirmation (may take several minutes).
