## Description

Sergej Kunz, co-founder of 1inch Network, presents a live product demo of 1inch Fusion at Pragma Lisbon 2023. Fusion introduces a new era of gasless, MEV-protected DeFi trading through asynchronous, Dutch auction-based order execution—empowering users with seamless swaps without paying gas fees. In this talk, Sergej walks through the evolution of 1inch, the motivations behind Fusion, and how it protects traders from front-running while offering better rates through professional market maker competition.

Learn how Fusion leverages permit-based limit orders, smart contract flexibility, and account abstraction principles to optimize trade efficiency. He also showcases the 1inch Wallet and how developers can easily integrate Fusion into their dApps using 1inch's SDKs and APIs.
