BSC (BEP20) Bundle

Stack: Python, Web3.py / Flashbots RPC, AsyncIO
Role: Backend / Blockchain Developer (Middle)

Project Description

Developed a service for forming, simulating, and sending transaction bundles in EVM-compatible networks (Ethereum, BSC, Polygon, etc.). The system allows packaging multiple transactions into one bundle, optimizing their order, checking execution "in the next block," and safely sending through Flashbots-compatible RPC nodes.

Key Features

Formation of bundles with an arbitrary number of transactions

Support for Flashbots and other private RPC (without entering the public mempool)

Pre-simulation of bundle execution (bundle simulation)

Automatic selection of optimal gas price / priority fee

Tracking the status of the bundle and the result of minting

Logging and alerting in case of sending errors or rejection

Asynchronous processing of multiple bundles simultaneously
