## Description

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.
