Open Source

FuzzingLabs' coverage-guided fuzzer for Cairo and Starknet smart contracts.

About

Cairo-Fuzzer is an open-source fuzzing tool from FuzzingLabs built to find bugs in Cairo programs and Starknet smart contracts. It performs coverage-guided input mutation against Cairo functions and can be used both as a standalone CLI and as a library within security workflows. Fuzzing is one of the few dynamic-analysis options available for the Cairo VM's unusual execution model, making this a practical addition to Starknet audit tooling.
