Zk audits and zero-knowledge security

In zero-knowledge systems, trust starts before a verifier returns true. A zk audit reviews cryptographic design, circuits or zkVM code, and proof enforcement across on-chain and off-chain components-so your protocol launches safe and reliable.

Noir zk audits

As an Aztec partner, we align with Barretenberg flows. Reviews cover types, gadgets, Nargo/NoirJS workflows, and production constraints.

Starknet audits

A recognized provider, with work on Starkgate, AVNU, Ekubo. We target Sierra→CASM correctness, Poseidon usage, account abstraction, and L1↔L2 messaging.

zkSync audits and verification

We formally verified the zkSync verifier (EasyCrypt) and serve on the zkSync Security Council, aiming to provide unmatched assurance.

Scroll audits

Focus on EVM-equivalence, RLP/ABI decoders, ROM vs EVM mismatches, and hash gadget constraints to prevent spoofed encodings.
