Building the Applications of the Future I Harsh Rajat

Sun, Nov 2, 2025, 12:00 AM

Harsh Rajat, co-founder and CEO of Pushchain, discusses building decentralized applications (dApps) for the future, focusing on the challenges of cross-chain development, interoperability, and user experience in Web3. He recounts Push's journey from ETHGlobal 2020, highlighting the importance of hackathons, community support, and VC funding in their growth. Harsh identifies key pain points: increased infrastructure management, codebase fragmentation, high audit costs, and user friction due to multiple wallets and bridging protocols. To address these, Pushchain introduces a universal shared state blockchain, enabling developers to deploy once and reach users across all chains with native experiences, simplified infra, and seamless interoperability. Pushchain leverages EVM tooling and a UI kit SDK for easy integration, abstracting away complexities for both users and developers. Harsh announces the Pushchain testnet launch at ETHGlobal Delhi 2025 and introduces the exclusive Auto Pass for hackathon participants. 00:00 Introduction 00:38 Pushchain Origin Story & ETHGlobal 2020 01:40 Growth, Traction, and Push’s Success 02:08 The Hacker’s Reality: Cross-Chain Challenges 03:02 Infrastructure and Interoperability Issues 04:12 Fragmentation, Audit Costs, and User Friction 05:55 Rethinking dApp Development: The Pushchain Vision 06:22 User Experience: Present vs. Future 07:41 Pushchain: Shared State Chain Explained 08:16 Developer and User Benefits 09:00 Building on Pushchain: EVM Tooling & UI Kit 09:29 Code Integration Example 10:13 Pushchain Testnet & Auto Pass Announcement 10:52 Conclusion & Q&A _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇮🇳 *Pragma New Delhi* Pragma New Delhi 2025 was held on September 25th at the JW Marriott Hotel in Aerocity New Delhi and was an in-person summit for builders and leaders in the web3 ecosystem.
