Manuel

Biography

Lead Security Researcher (LSR) at Spearbit, focused on Ethereum/EVM. 60+ reviews since 2021 across Uniswap, Sky/MakerDAO, Optimism, Base, Aztec, Monad, Centrifuge, Usual, and more.

Manuel has been working with Ethereum since 2016. Over the past four years at Spearbit/Cantina, he has uncovered high-impact vulnerabilities across DeFi, L2s, governance, and bridges, and contributed to their overall design.

Previously, he was a Lead Engineer at Centrifuge, where he designed and developed smart contracts securing over $250 million in TVL and enabled the first real-world assets (RWAs) on MakerDAO. In that role, he worked closely with security companies on audits and gained engineering-side perspective on the review process.

He also contributed to Radicle Drips, a highly optimized streaming protocol for open-source dependency funding, where he helped design the system and reviewed all PRs of the first versions.
