I am building Phylax, a new startup in hack prevention. Phylax will initially launch a free and open-source (AGPLv3) agent that enables developers to easily monitor their dapps by defining alerts in solidity! Instead of having to learn bespoke SDKs or use SaaS-based, closed-source systems, users can deploy Phylax and run assertions (alerts) about their dapps using the language and framework they already know: Solidity and Foundry. The tools that exists are either hard to use and expressive (developers can express any kind of alert over onchain state) or easy to use and very restricting. Phylax does both by leveraging the mental models the devs already have and the toolchains that everyone uses. That means that they can be productive in literal minutes, over hours or weeks that is usually required to setup a monitoring solution. At the same time, they can define onchain or offchain actions in case the alerts go off. Phylax Node will always be a free and open source piece of software, aiming to enable developers to offer a higher degree of security to their users. Phylax is currently in private alpha and will release soon.
