Testimonials
Our services are tailored to our customers
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!
Centrifuge
Jeroen - CTO
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.
Liquity
Rick - Cofounder
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.
Badger DAO
James - Lead Dev
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.
Corn
Dapp - Cofounder
Engaging with Alex&Lourens showed great proactiveness to answer deep-technical Qs along the process and help to discuss together items that require deeper drilling on invariants, really valuable not only their ability to answer Qs, but educating you on the process and empowering your team for better understanding of invariants on your architecture!
Onchainification
Petrovska - Cofounder
Alex has an incredible eye for detail, leaving no stone unturned during our audit. His review helped us gain confidence in our codebase before going to a competitive audit. I would highly recommend Alex’s security services to anyone building smart contract systems.
Solidity Labs
Elliot - Founder
We worked together with Alex to review a Safe module for our DAO multi-sig. We really valued his proactiveness and quick response times so that we could ship in a timely manner. 🚀
Balancer DAO
Xeonus - Balancer Maxis
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.

Thomas Hepner - Cofonder & CTO
Alex had the most transparent and interactive process of any auditor I've worked with. He was very proactive and provided in-depth analysis even beyond what was initially requested. In the end, our team was able to iterate on findings a lot quicker than we'd estimated, while also learning a huge amount along the way

THE MISSING PIECE
Invariant Testing is often the missing piece to reduce the number of bugs protocols go to audit with
CODE THAT GROWS WITH YOU
Invariant Tests help you specify your system behaviour, helping increase it's predictability
NEVER MAKE THE SAME MISTAKE AGAIN
Invariant Tests can run on every edit, meaning once you fix a bug, they'll check against it
WORLD CLASS MANUAL REVIEW
Recon Audits are lead exclusively by seasoned vetrans, we only take audits for which we have an edge
RECON PRO
Our fully developed cloud platform saves you time with features nobody else has built. Recon Pro is included in every engagement
LIVE MONITORING
Recon suites are easily reusable for live monitoring, these tests try to predict exploits instead of
Trophies
Recon was used to find these bugs
Audits
World Class Reviews, we open source every audit unless asked not to by our customers
TEAM
SERVICES
Boutique Audits, we can write code and break invariants, whether you want us to code with you perform manual review
We can support your team at all stages of development
Early Stage:
Define key invariants, scaffold and maintain invariant testers
Add invariants as the project grows
Pre Audit Stage:
Reach 100% Coverage, handout to your Auditors a full set of test repros to produce meaningful states or broken properties
Solo Review Stage:
Recon is made by highly respected SRs that can help you with Manual Review
Audit Stage:
We can support you during audits, by adding new properties flagged by your reviewers and by reproducing bugs in invariant tests as a means to ensure they are not introduced later
Our cloud runners ensure you can quickly queue and test fixes, no more waiting for your engineer to come back from the weekend
Our offers:
- Manual Review > A high quality review done by top Security Researchers, ideally paired with Invariant Testing
- Invariant Test Writing > Testing written by an experienced fuzzing engineer, for projects that want to skill up their codebase, includes unlimited cloud runs during the engagement
- Recon Pro > Cloud Fuzzing as a service, a versatile and easy way to run invariant testing in the cloud
