Quantstamp is a blockchain security firm founded in 2017 that provides expert Web3 security assessments, including smart contract audits, infrastructure and Layer 2 audits, zero-knowledge circuit reviews, and economic exploit analysis. The company has conducted over 1,300 audits across more than 60 blockchain ecosystems and helped secure billions of dollars in digital assets. Quantstamp publishes public audit reports through its certificate portal, maintains open-source Web3 security tooling on GitHub (L2 block explorer standards, ERC-4337 checkers, halo2 zero-knowledge libraries), and runs a research blog. Quantstamp is a services and consulting provider rather than an API-first platform, and does not currently publish a first-party developer API or OpenAPI specification. Backed by SoftBank Vision Fund.
