Secure your blockchain stack from the smart contract layer to the key vault
In blockchain and DeFi, every key and contract safeguards a live and liquid value, but adversaries are better‑resourced, faster‑moving, and far more relentless than those targeting traditional Web2 systems.
NCC Group experts help you understand your unique risks and reduce exposure to real‑world threats across contracts, dApps, applications, custody, and operational workflows.
Safeguard digital assets from exploitation.
Proactively identify and remediate critical vulnerabilities in smart contracts, dApps, and custody systems. This reduces the risk of token loss, fund misappropriation, or protocol compromise caused by technical flaws or malicious attacks.
Accelerate secure launches.
Whether you are deploying smart contracts, launching a Web3 product, or establishing custody infrastructure, our expertise enables you to go to market with confidence. This helps you avoid costly delays, emergency patches, or reputational damage.
Comprehensive security across your ecosystem.
Go beyond on-chain analysis to assess your full attack surface. From business logic and access controls to development workflows and human factors, we help close security gaps across your entire technical and operational landscape.

Our services
Assessment
Smart Contract Security Assessment
Comprehensive audit of deployed and in‑development smart contracts, including logic review, attack surface mapping, and deep vulnerability analysis. Includes manual testing, fuzzing, exploitation, and secure coding best practices.
Assessment
Web3 Application Security Assessment
Assessment of dApp frontends, blockchain interactions in off‑chain components, and crypto‑related trading and custody flows. Focus areas include race conditions, replay attacks, and logic vectors that could mislead users into approving malicious transactions.
Assessment
Crypto‑Custody and Operational Security Assessment
Comprehensive evaluation of key management systems, approval workflows, and supporting infrastructure. This includes architecture reviews, end‑to‑end testing of Web3 and mobile applications, and threat modelling across the entire operational environment. We identify trust boundaries, insider risks, potential compromise paths, and business continuity weaknesses from privileged roles and secure enclaves to the human factor in Zero-Trust environments.
From DeFi Startups to traditional institutions, we can secure your entire blockchain stack.
