Daniel Gelfand is a smart contract auditor and co-founder of Guardian Audits, an onchain security organization specializing in smart contract audits, penetration testing, and technical risk reviews. Daniel's Twitter Score is 9.1 out of 1000 as of October 2026, ranking #101,794 among 492,820 tracked accounts.
Daniel co-founded Guardian Audits after an early experience building a DeFi protocol that suffered a critical bug post-launch, requiring the team to rescue user funds before pivoting to security work. The organization has since grown into a recognized audit firm, with its public repository covering major protocols including GMX, Beefy Finance, Ethena, Jupiter, LayerZero, Synthetix, Yuga Labs, and others. Guardian's website reports more than $44 billion in digital assets secured across its engagements.
Daniel participates directly in audit work alongside the broader Guardian team. A published report documents his involvement in reviewing Orderly's Omnichain contracts in June 2024, as one of six auditors who identified ten High and Critical issues during that engagement. Beyond client audits, Guardian Audits also operates Solidity Lab, a free community and knowledge base for Solidity security, and Sentry, a smart contract security platform with AI-assisted analysis. Daniel has published 970 posts on the platform.
