Documentation for eth_defi.anvil Python module.

Anvil integration.

Anvil is a blazing-fast local testnet node implementation in Rust.
Anvil can replace eth_tester.main.EthereumTester as the unit/integration test backend.
Anvil is mostly used in mainnet fork test cases.
Anvil is a more stable an alternative to Ganache (eth_defi.ganache)
Anvil is part of Foundry, a toolkit for Ethereum application development.

To install Anvil on your UNIX computer:

curl -L https://foundry.paradigm.xyz | bash
PATH=~/.foundry/bin:$PATH
foundryup  # Needs to be in path, or installation fails

This will install foundryup, anvil at ~/.foundry/bin and adds the folder to your shell rc file PATH.

For more information see Anvil reference.

See also eth_defi.trace for Solidity tracebacks using Anvil.

This code was originally lifted from Brownie project.
