Decidable Systems Formal verification for
security-critical Rust

An audit finds bugs.
A proof eliminates them.

We use formal verification to prove your Rust correct, even if it uses unsafe. A proof holds for every input, not just the paths a reviewer had time to review. The bug classes it covers are provably gone, and unlike an audit, the proof stays checkable as your code changes.

How we start

A fixed-scope engagement: we verify one critical module or unsafe boundary and hand you a machine-checked proof and a written report. We’re building that into continuous verification, where proofs re-check on every commit, and design partners are first in line.
