Mike Liu, engineering lead at Gemini, presents the Gemini Wallet at a developer-focused workshop. He explains the motivation for building another wallet: to offer a composable, modular, and developer-friendly solution based on industry standards like ERC-4337, ERC-7579, and ERC-7484. The wallet supports both custodial and non-custodial use, integrates with Wagmi and RainbowKit, and is embeddable and portable for seamless dApp integration. Gemini Wallet sponsors gas fees on testnets and major L2s, simplifying development and onboarding for both hackers and end-users. Features include passkey authentication, ENS subdomains, WalletConnect compatibility, and multi-sig support. Liu emphasizes composability, open standards, and ease of use, encouraging developers to build on top of Gemini Wallet rather than creating new wallets. The workshop also highlights Gemini’s commitment to supporting the builder community with bounties and easy integration. 00:00 Introduction 00:30 Why Build Another Wallet? 01:10 About Gemini and Mike Liu 01:53 Security and Developer Focus 02:12 Passkey Authentication & Industry Standards 03:10 Product Overview: keys.gemini.com & onchain.gemini.com 04:10 Gas Sponsorship & Developer Incentives 05:00 Wagmi Integration & Ease of Use 06:02 Supported Networks & Future Plans 07:10 Embeddable & Portable Wallet Features 08:11 User Experience & Embedded Wallets 08:45 Gemini Wallet Core Package & RPC Compatibility 09:24 WalletConnect & Integration Details 09:47 Onboarding New Users & ENS Subdomains 10:38 dApp Integration & Hackathon Opportunities 12:02 Transaction Demo & User Flow 12:53 Wagmi & RainbowKit Connectors 13:46 Gemini’s Onchain Presence & Community Support 14:20 Composability, ERC-7579, and Modular Accounts 15:48 Multi-sig & Module Support 16:20 Bounties, Gas Sponsorship, and Open Source Discussion 17:43 Final Takeaways & Q&A 18:08 Conclusion _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇺🇸 *ETHGlobal New York* This workshop is specifically for ETHGlobal New York, a 3-day hackathon held August 15-17, 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!

Conflux - Web3 UX Unconference · Nov 16, 2023

No description The video features an opening speech from a conference in Istanbul addressing the UX community. Despite regional challenges and the absence of some colleagues, the speaker appreciates attendees' presence at DevConnect and encourages them to enjoy the additional activities available, including Turkish ice cream and coffee. The speech explains that the UXLand conference is an "un-conference," where participants create the event by discussing topics of interest to them. The conference has no sponsors or volunteers but is supported by the Ethereum Foundation and DevConnect. The speaker emphasizes that the success of the event depends on attendee participation and stresses that it's a collaborative environment rather than a platform for promoting individual projects. Attendees represent various professional backgrounds, with product development, engineering, and design being prominent. Key topics for discussion include account extraction, user onboarding, Web3 design principles, and general adoption within the ecosystem. Working groups will form to delve deeper into these areas in a collaborative setting with provided tools like FigJam for documentation. The speaker also mentions a goal of creating memorable ways (memes) to communicate complex UX concepts outside of the conference to foster broader understanding and excitement. An example given is "4337," which has gained attention despite many not fully understanding it. The video outlines rules for speakers, including strict time limits,

Ethereum Denver · Oct 9, 2023

In this video, we delve into the fascinating world of ERC-4337. We'll take you on a journey through the intricate account abstraction system architecture and explore how it functions. Additionally, we'll guide you on leveraging the powerful API and SDK that have been meticulously crafted for generating UserOperations to seamlessly interact with the EntryPoint contract. Throughout the video, we'll unravel the complexities surrounding ERC-4337 and shed light on its inner workings. You can expect a comprehensive overview that covers all essential aspects of this innovative system. From understanding its architecture to learning how to effectively build upon it, we've got you covered. Join us as we dive deep into ERC-4337 and equip ourselves with valuable insights about this cutting-edge technology. Stay tuned for an engaging exploration of ERC-4337's capabilities! #ERC4337 #AccountAbstractionSystem TLDR: Account abstraction simplifies transaction validation and execution on the Ethereum network by using contract accounts, entry points, paymasters, and bundlers, allowing for batch execution, alternative execution mechanisms, and authentication with session keys. 00:00 📝 An account abstracted account simplifies validation, execution, and gas payment by using contract accounts, entry points, paymasters, user operations, and bundlers, allowing applications to create transactions that are validated by bundlers before being added to the Ethereum chain. 02:45 🔍 ERC-4337 wallets validate transactions through contract calls, verifying account code, paymaster, and gas before executing on Ethereum network. 05:29 💡 Account abstraction enables the validation and execution of transactions using code, allowing for batch execution and alternative execution mechanisms, while a paymaster contract extracts tokens from users to pay for transactions. 08:46 🔑 Account abstraction allows for authentication with session keys, which can be used for low-security mechanisms like gaming, as well as for corporate accounts with different signers. 09:52 💡 Different roles in a Dao can have different security mechanisms, such as token payments or sponsor paymasters, allowing for various use cases and the need to build. 11:20 🔑 A browser extension called Trampoline allows users to create and customize account obstructions with different signature check mechanisms, providing a user-friendly experience for onboarding and transaction handling. 13:20 📝 Account abstraction allows for the creation of accounts without the need for additional mechanisms, with the process involving providing constructor code, handling nons, creating an execution function, and using an onboarding component to collect user information and create the account. 15:34 📝 The speaker shows how to create an account, load source into metamask, and execute transactions in a custom UX, as well as connecting to a sample application on etherscan using metamask and mentioning the use of a bundler for user operations. Dror Tirosh ERC-4337 lead developer ERC-4337 core team (previously OpenGSN) Dror has over 30 years of experience in software development. In 2018 he entered the web3 space, starting as the lead developer in Tabookey, followed by the OpenGSN project, and finally joined the ERC-4337 core team
