Independent smart contract security researcher
About me
Hi, I'm keterka. I spent years in software development before moving into smart contract security, and I hold a B.Sc. in Computer Science. Today I audit DeFi protocols in Solidity, privately with Phage Security, Pashov Audit Group, CODESPECT and Shieldify Security, and in public contests, where I'm Top-18 on HackenProof.
I'm strongest on lending, perpetuals, RWA vaults and liquidity management. For a private audit, message me on Telegram @makamert.

Selected findings
Phantom liquidity from quota removal
Removing a user quota wrongly decremented totalUsed, breaking the core accounting invariant: the system could allocate more liquidity than actually exists.
Dust deposits break pool accounting
Dust deposits round to zero, so totalLiquidity grows while allFunds doesn't. Small deposits are lost entirely, and a ~0.5 USDT grief cuts LP rewards by up to 45%.
