Public information

About

FuzzingLabs is an offensive cybersecurity company headquartered near Paris, France, specialising in vulnerability research, fuzzing and continuous offensive validation. Alongside its FuzzForge platform for firmware and binaries, its trainings and its AI, cryptography, mobile and telecom services, it runs a blockchain security and audit practice. This practice covers design and architecture (whitepapers, economic models, governance), layer 1 node implementations and consensus, layer 2 rollups and settlement, smart contracts (DeFi, DAOs, oracles), off-chain components such as dApps, wallets and bridges, cryptography including zero-knowledge proofs, developer tools such as compilers, and hardware wallets. Its eight-step audit process runs from scoping and threat modelling to in-depth code review, dynamic testing and fuzzing, reporting, fix verification and final sign-off. The site names ecosystems including Solana, Stellar, Ethereum, Near, Starknet, Algorand, Sui, Aptos, Cosmos and Polkadot. FuzzingLabs builds open-source security tools, among them sol-azy for static analysis and reverse engineering of Solana programs, a Cairo and Starknet fuzzer and a Sierra analyzer, and publishes audits and research in a public GitHub repository.
