By following this workshop, developers will be able to identify complex security issues that cannot be detected with conventional unit and parameterized tests. The goal of these properties is to detect vulnerabilities or deviations from expected results, ensure adherence to standards, and provide guidance to developers writing invariants.

Interval properties (ex: min(x,y) <= avg(x,y) <= max(x,y)).

Negative reversion properties for functions that should not revert for certain ranges of input.

Reversion properties for functions which should revert for certain ranges of input.

Differential testing properties (ex: 2^(-x) = 1/2^(x)).

Communicative, associative, distributive, and identity properties for relevant functions.

Non-spec security properties (share inflation attack, token approval checks, etc.).

Functionality properties (ex: redeem() deducts shares from the correct account).

Differential testing properties (ex: deposit() must match functionality predicted by previewDeposit()).

Reversion properties for functions that must never revert.

Properties that verify rounding directions are compliant with spec.

Properties for extensions such as burnable, mintable, and pausable tokens.

Inferred sanity properties (ex: no user balance should be greater than token supply).

Properties for standard interface functions.

This release contains tests for the ABDKMath64圆4 library, ERC-20 token standard, and ERC-4626 tokenized vaults standard: This collection of properties is simple to integrate with projects that use well-known standards or commonly-used libraries.

The repository and related workshops will demonstrate how fuzzing can provide a much higher level of security assurance than unit tests alone. March 14 – ERC4626 properties, example usage, and tips on fuzzing effectively ( Benjamin Samuels) Why should I use this?.March 7 – ERC20 properties, example usage, and Echidna cheat codes (Guillermo Larregay).Since mastering these tools takes time and practice, we will be holding two livestreams on our Twitch and YouTube channels that will provide hands-on experience with these invariants: Properties covered include compliance with the most common ERC token interfaces, generically testable security properties, and properties for testing fixed point math operations. To help the community define properties, we are releasing a set of 168 pre-built properties that can be used to guide Echidna, our smart contract fuzzing tool, or directly through unit tests.

This technique relies on the creation of code properties – often called invariants – which describe what the code is supposed to do. As smart contract security constantly evolves, property-based fuzzing has become a go-to technique for developers and security engineers.
