Quantstamp is a blockchain security company that performs smart contract audits and builds automated security tools and protocols for Web3 projects. Audits examine smart contract code for logic errors, reentrancy bugs, and other vulnerabilities before protocols go live, addressing a category of risk that has led to some of the largest losses in the history of decentralized finance.
Founded in 2017 by Richard Ma and Steven Stewart, Quantstamp went through Y Combinator and has grown into one of the longer-tenured independent firms in smart contract security, maintaining local subsidiaries in Canada, Japan, Germany, and China to serve clients across regions.
The company has raised funding across multiple rounds, including an early token-linked Series A, and reports having audited protocols that collectively secure well over $100 billion in value, though exact current figures vary by source.
Innovation Matrix Assessment
A long-tenured firm (since 2017) that has expanded internationally but shows steadier, less headline-driven iteration than newer entrants.
Smart contract audits are essential, practical infrastructure for any team launching on-chain code, directly reducing the risk of exploit-driven losses.
Nearly a decade of operating history, YC backing, and international subsidiaries indicate durable, if not explosive, market presence.
Quantstamp was an early mover in smart contract auditing, but the category has since become a mature, increasingly commoditized service with many competing audit firms.
A long audit track record and continued operation since 2017 are evidence of sustained client trust, though 'value secured' figures are self-reported and vary across sources.
Smart contract security remains a necessary, if narrower, niche as long as decentralized protocols continue to hold meaningful value.
Why CISOs Should Care
For organizations building or integrating with blockchain infrastructure, provides independent, specialized review of smart contract code before deployment.
What Makes It Different
One of the original dedicated smart-contract-audit firms, with its own automated security tooling layered on top of manual review.
The Matrix Verdict
57/100 — INCREMENTAL INNOVATOR
An Incremental Innovator: a durable, credible specialist in a now-mature niche, rather than a fast-moving disruptor, reflecting steady relevance rather than renewed category-defining innovation.
Editorial Note: Claims vs. Verified Findings
Headline figures like '$200B+ secured' are vendor- and industry-site-reported aggregates that vary by source and were not independently re-verified line by line.
