MferSafe Lite

About

MferSafe Lite is a powerful browser extension designed to improve the transaction experience for smart contract wallet users. With its innovative transaction bundling capabilities, users can execute multiple transactions simultaneously, without waiting for each individual transaction's confirmation.
Requirements:
MferNode backend: Simulates transaction bundles and provides state diffs. You can host your own node using a simple Docker Compose setup. For more information, visit: https://github.com/sec-bit/mfer-node
Web3 RPC: For eth_call, as some dApp frontends do not support state override (we recommend using Alchemy.com)
Process:
MferSafe Lite receives parameters for eth_sendTransaction(tx) and sends them to the MferNode backend for simulation.
MferNode returns the state diff (i.e., the state changes that the transaction will cause).
The browser extension injects the state diff into every eth_call() as the last parameter for state override.
