Step 2: Install era_test_node

era_test_node allows you to run an in-memory node of ZKsync Era. Grab it from the official ZKsync docs:

🔗 Installation Guide (https://docs.zksync.io/build/test-and-debug/in-memory-node)

Step 3: Fork ZKsync Mainnet

Start the node and fork the mainnet to have a local replica of ZKsync mainnet! 🍴

Step 4: Configure Your Environment

Set your ETH_RPC_URL to point to your local node to tell cast and other tools to use your local fork. 🌐

Step 5: Test the Setup

Check the chain-id to verify everything is working, output should be 260.

You've successfully set up a local ZKsync environment with era_test_node and Foundry to it! Next up, we'll make life easier with some .env shortcuts. Stay tuned!

Step 1: Install Foundry

Foundry is a blazing-fast Ethereum development toolkit. Install it to get equipped with forge and cast ⚒️
