Fuzzing Around: Better Smart Contract Testing through the Power of Random Inputs
3 projects | dev.to | 25 Apr 2023

Fuzzing has been around for a while in traditional full-stack development, but a new class of tools is here that can apply fuzzing to smart contract testing in web3. Some of the fuzzing tools include the open source Echidna and MythX.
Smart Contract Audits with ConsenSys Diligence Fuzzing - Fuzzing as a Service
3 projects | dev.to | 7 Apr 2023

Fuzzing has been around for a while. Defensics and Burp Suite are some examples in the traditional development world. There are also several web3/blockchain fuzzing tools available, such as Echidna and Foundry. However, Diligence Fuzzing is fuzzing as a service and makes everything a little simpler to implement. Which in the end means better audits and more secure contracts. So let’s look into it in more detail.
