Quantstamp

Quantstamp specializes in security assessments for blockchain applications and Web3 infrastructure. Its core service is smart contract auditing, where security researchers review code and protocol logic for vulnerabilities that could affect assets, permissions or application behavior after deployment. Quantstamp has published hundreds of public security reports and has worked across multiple blockchain ecosystems and programming languages. Its client base includes DeFi protocols, blockchain infrastructure projects and other Web3 organizations where software vulnerabilities can have direct financial consequences. The company’s audit work can cover more than individual Solidity contracts, extending into broader protocol and blockchain security assessments depending on the project. Public audit reports provide additional transparency into the types of security issues identified during engagements. Quantstamp is therefore distinct from general-purpose application security vendors: its specialization is decentralized systems and onchain financial infrastructure.
