Sergey Kunz

Co-founder & CTO · 1inch

Designed and implemented the Pathfinder routing algorithm, authored core aggregator smart contracts and led AMM (Mooniswap) development, directly shaping on-chain trade routing and fee capture.

As the principal technical lead within the founding team, took responsibility for building the on‑chain components that made the 1inch aggregator viable. Led the design and implementation of the Pathfinder routing algorithm and the set of smart contracts that split orders across multiple liquidity sources. Those implementations determined how swaps are decomposed, which pools receive flow and how gas and slippage tradeoffs are optimized in execution. Led in‑house development of the Mooniswap AMM concept and contributed core contract modules that 1inch deployed as part of its liquidity infrastructure. Coordinated and commissioned third‑party security audits of aggregator and AMM contracts, producing the audited releases that institutional integrators and liquidity providers relied upon. These concrete engineering deliverables directly affected the protocol’s ability to capture volume and the on‑chain behavior of the 1INCH token through fee flows and governance scope. Played an active role in on‑chain upgrade processes and cross‑chain deployments, implementing protocol updates that expanded the aggregator to additional EVM chains and improved routing efficiency. Also participated in defining the initial token distribution mechanics and technical governance hooks used later by the 1inch DAO, ensuring the protocol codebase embedded the governance primitives that shaped token utility and economic incentives.
