Blazing-fast Python bindings to revm

Quickstart

make install
make test

Example Usage

Here we show how you can fork from Ethereum mainnet and simulate a transaction from vitalik.eth.

from pyrevm import *

address = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045" # vitalik.eth
address2 = "0xBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB"

fork_url = "https://mainnet.infura.io/v3/c60b0bb42f8a4c6481ecd229eddaca27"

# set up an evm
evm = EVM(
    # can fork from a remote node
    fork_url=fork_url, 
    # can set tracing to true/false
    tracing = True, 
    # can configure the environment
    env = Env(
        block = BlockEnv( timestamp = 100
    ))
);

vb_before = evm.basic(address)
assert vb_before != 0

# Execute the tx
evm.call_raw_committing(
    caller = address,
    to = address2,
    value = 10000
    # data
);

assert vb_before != evm.basic(address)
assert evm.basic(address2).balance == 10000

Develop

We use Poetry for virtual environment management and Maturin as our Rust <> Python FFI build system. The Rust bindings are auto-generated from the macros provided by PyO3.

To build the library, run poetry run maturin develop

Note: If building for production, do not forget the --release flag, else performance will be degraded.
