Easily interact with and create anvil chains from python
anvil-web3 assumes anvil is already installed, click here if you don't have anvil installed
python3 -m pip install anvil-web3
This example shows how to programatically create an Anvil chain and how to inject the anvil rpc methods to a
web3.py Web3 object:
from web3 import Web3, HTTPProvider
from anvil_web3 import anvil, AnvilWeb3, AnvilInstance
# create an anvil chain
instance = AnvilInstance(
chain_id=42
)
# use the injection function
w3 = Web3(HTTPProvider(instance.http_url))
anvil(w3)
# or contruct a Web3 object from the AnvilWeb3 class (recommended for better autocompletion support)
w3 = AnvilWeb3(HTTPProvider(instance.http_url))
test_account = w3.eth.account.from_key(w3.keccak(text="42"))
# call an anvil method
w3.anvil.set_balance(test_account.address, 42424242)
assert w3.eth.get_balance(test_account.address) == 42424242 and w3.eth.chain_id == 42
instance.kill()More complex demos in /examples
