The Vision of United Defi I Sergej Kunz

Thu, Oct 2, 2025, 12:00 AM

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. 00:00 Introduction by Kartik 00:33 Sergej Kunz introduction 01:21 Current DeFi adoption stats 01:58 Comparing crypto to internet adoption 02:30 Institutional adoption & ETFs 03:23 Market cap & growth potential 04:07 The problem of fragmentation 05:06 Beyond Ethereum: multi-chain liquidity 06:08 Core advantages of DeFi 07:41 Composability & open protocols 08:47 Vision: unified liquidity layer 09:18 Intent-based cross-chain protocol 10:12 Unifying liquidity through arbitrage 11:36 Gasless user experiences 12:13 Economic impact of unification 13:24 Price improvements & execution 14:52 Reducing price slippage across chains 15:32 Improving user experience 16:46 The risks of bridging & MEV attacks 17:47 Intent-based architecture benefits 19:30 Chain abstraction for mass adoption 20:36 Path to United DeFi adoption 22:02 Global crypto adoption trends 24:28 Network effects & liquidity depth 25:42 Technical innovation: Dutch auctions 26:54 Benefits for users, protocols & LPs 27:56 Simple developer integration 28:35 Real-world impact & future use cases 29:23 Call to action: build with 1inch 30:23 Closing & Q&A mention _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *Unite Defi 2025* This ceremony was part of Unite DeFi 2025, an online hackathon sponsored by 1inch and held from July 25 to August 8.
