Force Sender

The Force Sender project explores the concept of forcibly sending native tokens to smart contracts. Unlike externally owned accounts (EOAs), smart contracts require a receive function or a fallback payable to accept native tokens.

This project demonstrates how to use the selfdestruct mechanism to compel the transfer of native tokens, even if the recipient contract doesn't implement a special function like receive or fallback.

Goals of the Project

The primary goal of the Force Sender project is to:

• Highlight Selfdestruct for Forced Native Token Transfer: Shed light on the utilization of the selfdestruct mechanism to forcefully transfer native tokens to contracts. By leveraging selfdestruct, native tokens accumulated within one contract can be seamlessly sent to an address without invoking a specific function, even if the recipient is a smart contract.

Technicalities of the Project

• Contract Creation using the new Keyword: Unlike previous projects that employed direct CREATE or CREATE2 opcodes with bytecode like Factory and Minimal-Proxy, this project uses the new keyword to create a new contract. This approach leverages a pre-defined contract template to streamline deployment.

• Usage of selfdestruct: While selfdestruct serves the purpose in this project, it is important to approach its usage with caution. This mechanism should be employed thoughtfully, and researchers must perform due diligence before utilizing it, especially considering ongoing discussions in the Ethereum Improvement Proposal (EIP) space about its deprecation.

• Documented with Natspec: The project's functions and overall functionality are documented using natspec, providing clear insights into each function's purpose and usage.

• Unit Tests with ethers.js: The project incorporates unit tests written with ethers.js to verify the functionality of the implemented contracts.

Note: The Force Sender project is educational and intended to explore the concept of forcibly transferring native tokens to contracts. It is not suitable for deployment in a production environment.
