Summary
🤩
Rockstar🎓
Top SchoolLasse Herskind is a Solidity developer with a decade of software experience, currently building privacy-preserving DeFi integrations at Aztec in the UK. He has hands-on protocol experience from Aave, where he upgraded core V3 smart contracts for newer Solidity versions and contributed tests and fixes to high-profile repos like aave-v3-core. His work spans DeFi primitives—deposits, withdrawals, flashloans—and addresses subtle rounding and edge-case issues that often surface in production. With a background at Deloitte exploring zero-knowledge proofs and a strong academic foundation from DTU, he blends formal engineering discipline with applied cryptographic and blockchain know-how. Colleagues describe him as the developer who anticipates protocol upgrade pitfalls before they hit mainnet.
