Crytic Properties Example (Foundry)

Sample repository for a crytic/properties + foundry 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 foundry tests.

These properties are designed to be verified using Echidna, and do not use Foundry's built in fuzzer. Running 'forge test' will not execute them.

Requirements

  1. Echidna is installed
  2. Run foundryup
  3. Run forge build

ERC4626 Properties

Contract under test is Basic4626Impl, which inherits from solmate's ERC4626 mixin.

Test harness is CryticERC4626InternalHarness

To run tests, use echidna . --contract CryticERC4626InternalHarness --config ./echidna.yaml
