ConsenSys has released its Diligence Fuzzing tool for smart contract security as DeFi losses accelerate in H2.
While the tool was previously released through a closed Beta requiring approval, it is now part of the smart contract toolchain Foundry.
MetaMask developer ConsenSys says the tool tests how smart contracts respond to semi-random and invalid inputs in specific states. Developers can access fuzzing features of dApp development tool Foundry for free before buying it.
According to the product’s web page, the tool is a “gray box” because it considers the smart contract state when creating test data. In contrast, a black box fuzzing tool would output significantly harder-to-predict data.
