Echidna is a weird creature that eats bugs and is highly electrosensitive (with apologies to Jacob Stanley) More seriously, Echidna is a Haskell program designed for fuzzing/property-based testing of Ethereum smarts contracts. It uses sophisticated grammar-based fuzzing campaigns based on a contract ABI to falsify user-defined predicates or Solidity assertions. We designed Echidna with modularity in mind, so it can be easily extended to include new mutations or test specific contracts in specific cases. Optional corpus collection, mutation and coverage guidance to find deeper bugs. Powered by Slither to extract useful information before the fuzzing campaign. Source code integration to identify which lines are covered after the fuzzing campaign. Curses-based retro UI, text-only or JSON output.
Features
- Generates inputs tailored to your actual code
- Support for a complex contract initialization with Etheno and Truffle
- Maximum gas usage reporting of the fuzzing campaign
- Seamless integration into the development workflow
- Automatic testcase minimization for quick triage
- Curses-based retro UI, text-only or JSON output
