Description
Echidna is a Haskell-based tool created for fuzzing and property-based testing of Ethereum smart contracts. It employs advanced grammar-driven fuzzing strategies that leverage a contract's ABI to challenge user-defined predicates or Solidity assertions. Designed with a focus on modularity, Echidna allows for easy extensions to incorporate new mutations or to target specific contracts under particular conditions. The tool generates inputs that are specifically adapted to your existing codebase, and it offers optional features for corpus collection, mutation, and coverage guidance to uncover more elusive bugs. It utilizes Slither to extract critical information prior to launching the fuzzing process, ensuring a more effective campaign. With source code integration, Echidna can pinpoint which lines of code are exercised during testing, and it provides an interactive terminal UI along with text-only or JSON output formats. Additionally, it includes automatic test case minimization for efficient triage and integrates seamlessly into the development workflow. The tool also reports maximum gas usage during fuzzing activities and supports complex contract initialization through Etheno and Truffle, enhancing its usability for developers. Ultimately, Echidna stands out as a robust solution for ensuring the reliability and security of Ethereum smart contracts.
Description
The hevm project serves as a tailored implementation of the Ethereum Virtual Machine (EVM) designed for tasks like symbolic execution, unit testing, and debugging of smart contracts. Created by DappHub, it seamlessly integrates with the suite of tools offered by the same developer. The hevm command line interface enables users to symbolically execute smart contracts, conduct unit tests, debug contracts interactively while displaying the Solidity source code, or execute any arbitrary EVM code. It allows computations to be carried out using a local state established within a testing framework or retrieved from live networks through RPC calls. Users can initiate symbolic execution with specified parameters to detect assertion violations and can also customize certain function signature arguments while keeping others abstract. Notably, hevm adopts an eager approach to symbolic execution, meaning that it initially strives to investigate all branches of the program. This comprehensive method enhances the reliability and robustness of smart contract development and testing.
