I’m Sourav Yadav, a smart contract security researcher and competitive auditor, currently an engineering student at IIIT Bhopal, India.
I actively audit DeFi and protocol-layer smart contracts across leading competitive platforms, with particular focus on identifying high-impact vulnerabilities involving:
- accounting inconsistencies
- protocol insolvency paths
- oracle manipulation/failure modes
- liquidation edge cases
- rounding / precision loss
- ERC4626 / ERC7540 vault risks
- AMM invariant violations
- asynchronous state desynchronization
- execution ordering / sequencing flaws
- denial-of-service attack surfaces
"I am particularly interested in vulnerabilities that emerge under realistic protocol evolution—such as interest accrual, virtual balance mechanics, and sequencing assumptions—where subtle design flaws can escalate into user-facing breakage or protocol-level failures."
I’m open to:
- private audits
- protocol security reviews
- long-term research collaboration
