About

Functori is a deep-tech consulting and development company registered as a French SAS in Ivry-sur-Seine, near Paris. It describes itself as research-driven, combining programming languages, formal methods and blockchain engineering. Its services cover blockchain core development across L1 and L2 stacks (consensus, data availability, execution environments, rollup orchestration), full-stack blockchain development with custom smart contracts, dApps and backend integration of blockchain nodes, and smart contract audits of Tezos and EVM-compatible contracts. Audits rely on formal verification, fuzzing, symbolic analysis, manual review and gas profiling, with attention to reentrancy, logic flaws, numerical bugs and upgradeability risks. The team works in OCaml, Rust, Solidity and TypeScript, and lists Michelson, Vyper, Ligo and SmartPy among audited languages.
