foundry - Ethereum Development Framework

Anvil

Anvil is a fast local Ethereum development node.

Anvil is part of the Foundry suite and is installed alongside forge, cast and chisel. If you haven't installed Foundry yet, see Foundry installation.

Getting started

To use Anvil, simply type anvil. To fork against a live Ethereum network run anvil --fork-url <RPC_URL>.

Let's fork Ethereum mainnet at the latest block:

anvil --fork-url https://reth-ethereum.ithaca.xyz/rpc

Notes

EIP-7702 and Default Accounts

Since the advent of EIP-7702, Anvil's default accounts have been delegated to drainers such as https://etherscan.io/address/0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266#authlist7702

This can negatively impact developer experience when users are running Anvil in fork mode and are making RPC calls that involve one of the default anvil accounts. To avoid this issue, use a different mnemonic when starting Anvil:

anvil --mnemonic "<custom mnemonic>" --fork-url https://reth-ethereum.ithaca.xyz/rpc
