Crytic Properties Example (Hardhat)

Sample repository for a crytic/properties + hardhat integration.

crytic/properties is a suite of Echidna properties/tests for common interfaces & libraries that can be added to your project to find unique bugs that cannot be easily found with unit tests.

These properties are designed to be verified using Echidna, and do not use Hardhat's testing functionality. Running 'npx hardhat test' will not execute them.

Requirements

  1. Echidna is installed
  2. Run npm install
  3. Run npx hardhat compile
