Build a 1 Click Cross-Chain Experience with Avail Nexus SDK I Robin Roy

Thu, Oct 2, 2025, 12:00 AM

Robin Roy presents the Avail Nexus SDK, a developer toolkit enabling seamless one-click cross-chain experiences for Web3 applications. Nexus abstracts away the complexity of multi-chain interactions, letting users bridge, transfer, and execute transactions across major EVM-compatible chains (like Ethereum, Optimism, Arbitrum, Base, Polygon, Scroll) without leaving the app or using third-party bridges. Key features include unified token balances, intent-based bridging, and bridge-and-execute functions, allowing developers to build cross-chain DEXs, yield aggregators, lending protocols, tipping clients, and gaming apps with minimal friction. The demo shows easy SDK integration, unified portfolio views, and transaction simulations. Nexus currently supports only EVM chains and liquidity must exist on supported chains. Resources, project ideas, and bounties are available for builders. 00:00 Introduction 00:50 Overview of Avail Stack & Products 01:22 What is Nexus? 02:23 Cross-Chain UX Challenges 03:10 Nexus SDK Features 04:07 Bridge and Execute Explained 05:11 Multi-Chain Application Use Cases 06:46 Bounties & Project Ideas 07:20 Live Demo: Integrating Nexus SDK 09:09 Unified Balances & Portfolio Aggregation 10:16 Bridging Tokens Demo 12:12 Developer vs User Experience 13:04 Bridge and Execute Demo 15:29 Code Walkthrough & Resources 17:23 Supported Chains & Q&A 18:13 EVM Compatibility & Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇫🇷 *ETHGlobal Cannes* This workshop is specifically for ETHGlobal Cannes, a 3-day hackathon held July 4-6, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
