World-class blockchain information security services

Smart Contracts

We have extensive experience in EVM and non-EVM based smart contract security reviews. Servicing the industry since the earliest days of Solidity, we have assessed a wide range of projects, some examples being; multi-billion dollar DeFi projects, low-level gas-saving assembly libraries, core protocol infrastructure and standard token contracts.

Zero Knowledge (ZK) Systems

We review various types of zero-knowledge systems, including custom circuits, provers, verifiers and all applications built on top of zero-knowledge platforms. We have developed a particular expertise in the Cairo programming language.

Blockchain Primitives & Infrastructure

As creators and maintainers of a popular Ethereum consensus client, we have unique expertise in securing core blockchain primitives, including novel cryptographic primitives devised in the blockchain context, p2p networks and their associated designs and applications, along with all forms of consensus mechanisms. We also review entire blockchain client implementations.

Layer 2 Protocols

We assess layer 2 software with a particular focus on new virtual machine implementations and associated languages, layer 2 sequencers, general architecture and infrastructure as well as any security risks based around decentralised trust on the layer 1.
