MferSafe Lite is a powerful browser extension designed to enhance the transaction experience for users of smart contract wallets. With its innovative transaction bundling capabilities, users can execute multiple transactions simultaneously, eliminating the need to wait for each individual transaction's confirmation.

To use MferSafe Lite, users need to meet certain requirements. They must have MferNode backend, which simulates transaction bundles and provides state diffs. Hosting your own node is possible using a simple Docker Compose setup. Additionally, users need Web3 RPC for eth_call, as some dApp frontends may not support state override (Alchemy.com is a recommended option).

The process of using MferSafe Lite is straightforward. The extension receives parameters for eth_sendTransaction(tx) and sends them to the MferNode backend for simulation. MferNode then returns the state diff, which represents the state changes the transaction will cause. Finally, the browser extension injects the state diff into every eth_call() as the last parameter for state override.

MferSafe Lite is a valuable tool for smart contract wallet users, providing a seamless and efficient transaction experience. By bundling transactions and optimizing the confirmation process, it streamlines the execution of multiple transactions, saving users time and effort.
