MLabs is a software engineering firm specialising in functional programming and formal methods, working largely on blockchain protocols, smart contracts and high-assurance systems. Its engineers work predominantly in Haskell and related languages, which is unusual commercially and gives it a niche in projects where correctness has to be demonstrated rather than tested, particularly in the Cardano ecosystem. Registered in London and operating as a distributed organisation, it takes on protocol development, audit and formal verification work for clients whose systems hold value that a defect would put directly at risk.
