Recon

Recon is a boutique audit firm, that is making Stateful Fuzzing (Invariant Testing) the new default

Check our Open Source repositories for:

  • Create Chimera App: The easiest way to start writing and running Invariant Tests, currently on it's 2nd version

  • Badger
  • Centrifuge
  • Corn
  • Smilee
  • Liquity
  • Solidity Labs
  • Onchainification
  • Balancer DAO

Our customers have over $1 BLN in TVL

Services

  • Recon Pro: Best in class way to run Echidna, Medusa, Foundry, Halmos and Kontrol in the cloud, with extensive automations, alerts and ongoing fuzzing utilities
  • Invariant Testing Engagements, bootstrap your invariants or maintain them with our extremely experienced engineers
  • Security Audits by Alex The Entreprenerd and other highly qualified, trusted, researchers
  • Ongoing onchain monitoring, automated invariant tests to prevent real world exploits

Trophies

We ran invariant tests against some of the toughest codebase

  • Badger - Crit
  • Centrifuge - Med
  • Tapioca - Highs and Meds

And many more we are awaiting for permission to publish

Best Practices

We offer multiple starter templates for invariant testing
