Manual security review of smart contracts across EVM and non-EVM chains. Our methodology covers the full spectrum of smart contract vulnerabilities: reentrancy, access control flaws, flash loan attack vectors, oracle manipulation, upgrade proxy risks, integer over/underflow, and critical business logic flaws.

We combine manual expert review with state-of-the-art automated tooling to achieve coverage that neither approach achieves alone. Every finding includes severity ratings, proof-of-concept exploits where applicable, and actionable remediation guidance.

Our audits go beyond application-layer contracts. We have reviewed RSKj virtual machine internals and trie structures, Evmos execution layer logic, IBC cross-chain routing and light-client relay logic, ZK-SNARK circuit isolation and proof aggregation middleware, Noise protocol handshake implementations, ephemeral key exchange, and ratcheting behaviors in distributed messaging systems — all at the source code and protocol specification level.

Full-scope adversary simulation engagements that test your organization's security posture against real-world attack scenarios. We cover external network attacks, internal lateral movement, social engineering campaigns, and physical intrusion where scoped.

Our methodology aligns with TIBER-EU and CBEST frameworks where required, ensuring regulatory compliance while delivering genuine adversarial insight. The goal isn't to find one vulnerability — it's to demonstrate the full attack chain an adversary would exploit.

Security assessment of the non-contract layer: node infrastructure hardening, RPC endpoint security, key management architecture (HSMs, MPC), validator security, monitoring & alerting setup, and threat modeling for protocol backends.

Smart contracts don't exist in a vacuum. The infrastructure running your chain, validators, and backend services is equally critical. We assess the full stack — from cloud configuration to key ceremony processes.

Previous engagements have included federated HSM-based signing infrastructure at RSK/RootStock, two-way peg bridge security, gas-cost inflation vector analysis, validator infrastructure at ZetaChain, and consensus fault detection on Solana, TON, and Sui core implementations.

Design-phase threat modeling and architecture review for protocols, bridges, L2s, and DeFi systems before code is written. Finding architectural flaws before implementation is orders of magnitude cheaper than fixing them post-launch.

We review your protocol design, trust assumptions, economic incentives, and system architecture to identify risks before they become vulnerabilities. This includes cross-chain bridge designs, rollup architectures, DeFi protocol mechanics, and governance systems.

Bespoke research engagements for vendors or protocols seeking deep-dive analysis into specific attack surfaces. Our research background spans CVE discovery, forensic analysis (Netherlands Forensic Institute), firmware reverse engineering, and embedded systems security.

Whether you need a targeted investigation into a suspected vulnerability class, a comprehensive security analysis of a new protocol design, or expert forensic analysis of a security incident, we bring researcher-grade depth to every engagement.

Fractional Chief Information Security Officer services for Web3 teams that need senior security leadership without the full-time overhead. We help you build security programs, define policies, and establish incident response capabilities.

From hiring your first security engineer to setting up bug bounty programs, security review pipelines, and compliance frameworks — we provide strategic security guidance tailored to the unique challenges of Web3 organizations.
