ErmanSec

DeFi security researcher focused on vault accounting and oracle security.

Currently deepening my expertise in smart contract security through hands-on research — identifying mathematical asymmetries in withdrawal functions, interest accrual logic, and oracle validation across lending and yield protocols.

Foundry-based mainnet fork testing with zero mock contracts is my standard approach. Privacy-conscious researcher;)

Focus areas:

• Vault accounting invariant violations
• Interest accrual and yield distribution asymmetries
• Oracle grace period and staleness bypasses
• Leveraged staking and lending protocol security
• ERC-4626 vault logic and share price manipulation
• Access control and timelock bypass vulnerabilities
• Flash loan interaction vectors
• DeFi smart contract security (Solidity / EVM)
