Flashbots Transaction Bundler

Description

The Flashbots Transaction Bundler is a Node.js application designed to create, sign, and send bundles of transactions to the Ethereum network using the Flashbots service. This application is specifically tailored for transferring ERC-1155 and ERC-721 tokens between wallets, ensuring that the transactions either all succeed or all fail, thereby minimizing the risk of loss due to failed transactions.

Features

Batch Transfer of ERC-1155 Tokens: Transfer multiple ERC-1155 tokens from one wallet to another in a single transaction.
Individual Transfer of ERC-721 Tokens: Transfer individual ERC-721 tokens from one wallet to another.
Gas Price Management: Calculate and set the optimal gas price for each transaction in the bundle.
Flashbots Integration: Send transactions in a bundle using Flashbots, thereby bypassing the public mempool.
