Quantstamp Review 2026: Web3 Security Services

Quantstamp is a Web3 security firm that offers audits and operational security services to blockchain teams. Its listed work includes smart-contract audits, formal verification, economic exploit analysis, penetration testing and infrastructure audits.

The firm also offers operational services such as security reviews, monitoring, incident response and vCISO support. It describes Chainproof as insurance for smart-contract hacks and slashing risks. These are services for project teams, not a consumer-facing DeFi application.

Quantstamp says it has operated since 2017 and reports conducting more than 1,300 audits across more than 60 ecosystems. It does not publish standard service fees, and clients should assess the scope and terms of each engagement. A 2023 SEC settlement concerned allegations over a token offering; the current regulatory status is not established here.

Quantstamp sells security services to Web3 teams. For an audit, the team and client define which code and systems are in scope. Auditors examine them for vulnerabilities and provide findings and recommendations; formal verification, economic analysis and infrastructure testing address other types of risk. The value of a report depends on its scope, the code version reviewed and whether identified issues are fixed.

The firm also lists services beyond one-time audits, including monitoring, incident response, operational security reviews and vCISO support. These are distinct engagements with their own terms. Quantstamp also describes Chainproof as an insurance product, but coverage conditions are not detailed here, so teams should check the policy before relying on it.

Quantstamp does not publish standard prices for its audits or other security services. Costs depend on the service and engagement scope; project teams can request a proposal from Quantstamp to see pricing and deliverables. The scope, exclusions and any follow-up work should be agreed before an engagement begins.

An audit can help identify weaknesses in the code and systems included in its scope, but it is not a guarantee against exploits. The reviewed code version, audit scope, remediation status and any exclusions all matter. Quantstamp does not publish standard fees or a single general audit guarantee.

Quantstamp describes Chainproof as an insurance product for smart-contract hacks and slashing risks, but coverage terms are not detailed here. A 2023 SEC settlement concerned allegations related to a token offering; current regulatory status is not established here. Teams should verify engagement terms and any insurance policy directly. This is a security-services provider, not a gambling service.

Quantstamp is aimed at Web3 developers, protocol teams and organizations responsible for blockchain infrastructure that need technical reviews or ongoing security support. It is not a consumer dApp for trading, lending or holding assets. Teams considering an engagement should define the systems to be reviewed and ask about deliverables, pricing, exclusions and follow-up.
