We worked with the phenomenal @getreconxyz team to get invariant testing coverage for the @centrifuge ERC-7540 implementation, leveraging their Recon Pro platform. Looking forward to seeing where @getreconxyz goes next, they have ambitious plans to take invariant testing to the next level!

We first met Alex during some excellent security discussions re: Liquity v1. The breadth and depth of his audit of our v2 exceeded expectations - particularly impressive for a solo effort. He uncovered several technical, arithmetic and economic issues and discussed them with us in detail. I'd highly recommend his manual reviews for any DeFi team that takes their security seriously.

Recon has allowed us to speed up the development of invariant tests immensely. We are able to create and execute test suites in the cloud effortlessly with virtually no boilerplate code. I highly recommend using Recon to automate your fuzzing setup.

The recon team is continuously innovating to make invariant testing vastly more accessible to projects, which makes a meaningful difference in security outcomes. They bring their broad expertise in and passion for web3 security to any engagement above and beyond the specified scope.

The ROI on our engagement with Recon was extremely high. They built an invariant test suite that uncovered hard-to-spot high-severity issues and gave us a powerful tool to ship with confidence. Moving forward, invariant testing will be core to our smart contract development at Credit Coop. When we do our next audit, Recon will have to be a part of the picture.
