méh₂tēr establishes structural trust parameters for global transactional infrastructure.
We engineer formally verified, zero-heap data containment systems and deterministic privacy primitives for enterprise operations. Powered by our core engine, Nona, our utilities operate on a stateless, zero-persistence boundary—backed by machine-checked Verus SMT proofs to eliminate memory safety vulnerabilities and side-channel timing leaks without compromising internal data silos.

Product Profile: Nona Engine
Our flagship cryptographic primitive, Nona, is a zero-heap, constant-time Private Set Intersection (PSI) engine engineered in #![no_std] Rust and mathematically validated via machine-checked Verus SMT proofs.
Nona operates with zero dynamic memory allocations (malloc/free) and empirical side-channel neutrality. It deploys seamlessly across enterprise environments as AWS Nitro Enclave images (.eif), Snowflake SQL C-UDFs, gRPC streaming proxy daemons (nona-proxy), zero-copy Python bindings (Polars/Arrow), and raw C-ABI static libraries (libnona_core.a).
