The Chain Abstraction Master Plan

Duration: 00:14:43

Speaker: Stephane Gosselin

Type: Talk

Expertise: Intermediate

Event: Devcon

Date: Nov 2024

Chain abstraction is vital for Ethereum’s future competitiveness and interoperability. This talk will dive into why Ethereum apps need chain abstraction to avoid fragmentation and ensure open, trustless, and modular systems. We’ll explore approaches to abstraction, the importance of open standards, and a roadmap for upgrading the ecosystem’s core infrastructure—spanning JSON-RPC API improvements, resource locks, and intent settlement—to unlock new layers of usability and decentralization.

The Wallet and UX Stack to Build Web3 Applications for the Masses

In this talk I will give an overview of how wallet infrastructure and the relationship between wallets and dapps have evolved over the past 5 years. And give a layer-by-layer breakdown of the modern wallet stack from signers to smart account modules, how each component contributes to a UX unlock on Ethereum/L2s, and how application developers can use them today. We will also touch on pertinent ongoing EIPs such as 7702 (deploy code for EOAs), and 7715 (permissions).

Bringing Ethereum to 1B Telegram Users

Learn how we use account abstraction to build an invisible wallet for 1 billion Telegram users. We will share our methods and learnings, showing how users and dapp developers will soon seamlessly interact with Ethereum, enjoying a smooth experience without ever realizing they are using a wallet. Features like biometric authentication will enhance user experience, while session keys make transactions invisible, ensuring secure and effortless interactions.

Achieving Chain Abstraction through Transaction Orchestration

Achieving chain abstracted experiences will require the ability to execute multiple transactions across multiple blockchains as a single "action", ideally with a single signature used for permissioning. In this talk I'll explore the concepts of transaction orchestration and single-signature, multi-chain permissioning. I will present what are the benefits, how to create such systems and what are the drawbacks (e.g. soft atomicity, stale permissions, etc...)

Who needs a wallet anyway?

This talk confronts the community’s obsession with decentralization purity at the cost of usability. This session explores how to hide the complexities of crypto, enabling seamless integration for users who may not even realize they are using a wallet. We’ll cover simplifying user interactions, making wallets function invisibly, maintaining benefits like permissionless innovation, managing thousands of wallets, and real-world applications. It’s time to push for real, user-friendly innovation.

Bootstrap Your dApp UX

What if we could streamline Web3 development, making it easy to prototype user-friendly dApps and drive mass adoption? Despite improvements, crypto's complexity makes intuitive design challenging. Many projects are developer-led, resource-constrained, and rushed to market, leaving little time for thorough design and user testing. In this talk, you'll learn to recognize common Web3 design mistakes and leverage best practices from DeFi and traditional finance to quickly bootstrap a user experience

Butterfly Effects + Paradoxes of Account Abstraction in DeFi

In this session, we’ll dive into the transformative potential of account abstraction in shaping the future of DeFi, exploring both its cascading impacts and inherent paradoxes. By pushing the boundaries of accessibility, onboarding, and wallet capabilities—such as multi-sig, social recovery, custom modules, transaction batching, and advanced transaction logic (ERC-7579)—account abstraction opens up new possibilities for collaborative DeFi, cross-chain interoperability, and enhanced composability
