/web3-flashbots

Web3.py plugin for using Flashbots' bundle APIs

Primary LanguagePython

web3-flashbots

This library works by injecting a new module in the Web3.py instance, which allows submitting "bundles" of transactions directly to miners. This is done by also creating a middleware which captures calls to eth_sendBundle and eth_callBundle, and sends them to an RPC endpoint which you have specified, which corresponds to mev-geth.

Example

from web3 import Web3, HTTPProvider
from web3_flashbots import flashbot
w3 = Web3(HTTPProvider("http://localhost:8545"))
flashbot(w3, flashbots_key_id="MY_API_ID", flashbots_secret="MY_API_SECRET", flashbots_url="http://localhost:8545")

Now the w3.flashbots.sendBundle method should be available to you. Look in examples/demo.py for usage examples

Test

  1. Clone and run mev-geth as instructed in the link
  2. PYTHONPATH=pwd && python examples/demo.py
