Foundry

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Foundry consists of:

• Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
• Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
• Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
• Chisel: Fast, utilitarian, and verbose solidity REPL.

Deploy VaultV2

The deployment script creates a new VaultV2 instance and configures it to work with a LidoAdapter. The script handles:

• VaultV2 creation via the VaultV2Factory
• LidoAdapter deployment and configuration
• Role assignment and timelock configuration
• Adapter registry setup and caps configuration

Run the deployment script:

# Run the deployment script (without block explorer verification)
forge script script/DeployVaultV2.s.sol \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY \
  --broadcast

# Run the deployment script (with verification on Etherscan)
# Refer to Foundry documentation for non Etherscan block explorers
forge script script/DeployVaultV2.s.sol \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY \
  --broadcast \
  --etherscan-api-key $ETHERSCAN_API_KEY \
  --verify
