## Description

In this keynote, Sergej Kunz, co-founder of 1inch, shares the long-term vision for United DeFi—an integrated, intent-based, and chain-abstracted infrastructure designed to bring the next billion users into Web3. He outlines the current state of DeFi adoption, the fragmentation challenges across blockchains and layer 2s, and how unified liquidity can eliminate inefficiencies. The talk explores how 1inch is building an intent-based cross-chain protocol that offers atomic swaps, direct P2P execution, and gasless transactions without bridge risks or wrapped assets.

Sergej compares today’s DeFi adoption to the internet’s 1997 moment, highlighting the path toward mass adoption. He explains why chain abstraction is key for user-friendly experiences, how liquidity unification reduces slippage and improves pricing, and the role of competitive market makers in driving efficiency. The roadmap shows how cross-chain composability and ecosystem-wide integration can unlock trillion-dollar opportunities for users, protocols, and developers.
