Scribble instruments Solidity code for runtime verification and property-based testing.
About Scribble
Scribble is an instrumentation tool that adds specifications to Solidity code for runtime verification and property-based testing. It is used to prepare smart contracts for behavior verification with Diligence Fuzzing and tools such as Mythril.
It installs with npm and runs from the command line on Solidity files. Its specification language uses a small set of constructs intended to be understandable and checkable with existing analysis tools, and is not intended to express every possible property.
Key features
- Instruments Solidity source code for runtime verification
- Supports property-based testing of smart contracts
- Prepares contracts for behavior verification with Diligence Fuzzing
- Works alongside analysis tools such as Mythril
- Command-line interface processes Solidity files directly
- Separate VS Code extension with syntax highlighting and hover hints
Best for: Developers and auditors working with Solidity smart contracts who use runtime verification.
Good for
- Open source under an Apache-2.0 license
- Installs globally via npm with command-line use
- Provides a separate VS Code extension for syntax highlighting and hover hints
Watch out for
- Specification language is not intended to cover every possible property
