Account Abstraction Community Hub

Modularity can be achieved through different constructions. Multiple inheritance can provide some modularity, but requires upgrades to add new features. Other approaches, such as ERC-6900 or ERC-7579, provide more dynamic solutions that can be reconfigured dynamically. During this talk, we'll review the upsides and downsides of each approach, and pave the way for a universal modular contract that could unify the space.

An honest, slightly chaotic lightning talk and open discussion about bringing EIP-7702 to life inside a browser extension. Featuring conversations, confused signers, and lessons learned from trying to integrate EIP-7702 with popular hardware wallets.

EIP-7702 brings Account Abstraction (AA) benefits to EOAs while maintaining their existing structure. In this workshop, the Etherspot team will guide you through integrating the censorship-resistant EIP-7702 infrastructure SDK (Free and Simple). Wallet teams will learn how to reduce infrastructure costs and unlock advanced AA features. dApp developers will discover how leveraging the 7702 infrastructure enhances UX, reduces friction, and drives stronger user adoption.

Its Shared Mempool architecture removes single points of failure, ensuring reliability, censorship resistance, and smooth user experience at scale. With 500K+ users already active across Korea and Japan, Rewardy demonstrates how familiar Web2 user flows can translate into real Web3 usage. In this session, we’ll walk through our AA integration and share what actually works when bringing mainstream users on-chain.

OSO collaborated with the ERC-4337 core team to index 230M+ user operations (Oct 2024-ongoing) across the Superchain. This demo covers data ingestion (decoding raw 4337 traces/logs), SQLMesh models (staging tables → event models → chain metrics), onchain attribution (EAS registries identifying 90%+ of bundlers/paymasters), and public access (BigQuery, GraphQL API, pyOSO library). Learn to query AA data, understand metrics and events, and explore open data standards built with the AA community.

A demo of how Account Abstraction powers dDocs and dSheets (onchain alternatives to gdocs & excel) by enabling self-sovereign collaboration flows for privately managing onchain documents and spreadsheets, individually or as a group.

We’ll share insights on the most popular EIP-7702 delegator contracts from the perspectives of authorizer count and TVL, analyzing specific use cases such as sweepers, utility contracts, and account abstraction. We’ll then take a deeper look at what makes these EIP-7702 delegator contracts stand out under account abstraction — including whether they comply with ERC-4337 or adopt modular ERC standards like ERC-6900 or ERC-7579.

AI Agents have quickly gone from a gimmick to a serious tool which can help users manage their yield and automate repetitive tasks. Smart Accounts are the perfect infrastructure for powering AI Agents as they enable complete abstraction of the complexities of execution, leaving agents free to express desired outcomes, which are then exeucuted by Relayers and solvers on top of Smart Accounts. This will be a discussion around the challenges and solutions of using ERC-4337 and other Smart Account infra to enable AI agents to use EVM chains

We’ll be showcasing an Agent-to-Agent (A2A) payment flow built on ERC-4337 infra, where agents discover trustless counterparts via ERC-8004 and execute onchain payments. The demo uses a Safe Account via the Brewit App (https://brewit.money) and Smart Sessions (ERC-7579) to enable permissioned, delegated payments to other agents and MCP tools using the x402 spec. An x402 UserOp-based facilitator verifies/ executes transfers through a bundler. The demo highlights Brewit’s interface for managing agent permissions and payments, powered by Google’s ADK and Claude/Cursor clients.

Quantum computers threaten Ethereum's cryptographic foundation. This talk explores practical post-quantum account abstraction using EIP-4337 and EIP-7702. We survey the quantum threat landscape, review current post-quantum EIPs (8051, 8052), and demonstrate how ZKNOX's Kohaku Wallet implements PQ-resistant smart contract accounts you can deploy today. Learn how to future-proof accounts against quantum attacks while maintaining compatibility with existing Ethereum infrastructure.

Post-quantum signatures like ML-DSA (Dilithium) are large and computationally intensive, a major challenge for hardware wallets with limited memory and processing power. This talk presents the first successful full-stack implementation of ML-DSA (EIP-8051) on a secure element chip. We share performance benchmarks, memory optimization techniques, and security considerations for building PQ-resistant hardware signers.

This demo explores how invisible wallets are revolutionizing Web3 onboarding, with real-world examples like Focus Tree's success in onboarding over 800,000 users from mobile stores. We'll showcase the power of Account Abstraction on Starknet, particularly in gaming applications, demonstrating how passkeys, session keys, and Web2-like experiences are making blockchain accessible to Web2 users.

This session offers a complete walkthrough, covering an architecture deep dive, creating secure Solidity smart contracts, and implementing a reliable Foundry-based CI/CD pipeline for testing and deployment.

We’ll present Piggy Wallet and how we’re onboarding non-crypto families to their first onchain experience using Account Abstraction (AA). We’ll cover the problem we’re solving in emerging markets, how our parent-child smart accounts work, and the specific AA patterns we leverage (e.g., gas abstraction, session keys, recoverability) so users interact with a wallet without realizing they’re using blockchain. The talk includes a short demo and actionable lessons learned from real beta testing.

EIP-7702 brings Account Abstraction (AA) benefits to EOAs while maintaining their existing structure. In this workshop, the Etherspot team will guide you through integrating the censorship-resistant EIP-7702 infrastructure SDK (Free and Simple). Wallet teams will learn how to reduce infrastructure costs and unlock advanced AA features. dApp developers will discover how leveraging the 7702 infrastructure enhances UX, reduces friction, and drives stronger user adoption.

Traditional finance giants are rolling out DeFi features wrapped in polished interfaces that reach their existing massive audiences. J.P. Morgan's 53+ million mobile banking customers just in the U.S. or Robinhood's 25+ million users dwarf DeFi's 20 million total users. How can DeFi apps keep up today? Come get insights on how account abstraction is fundamental to successful modern DeFi apps and how to implement it. Small group format for deeper technical discussions.
