Hey is a decentralized social media application built on the Lens Protocol. It provides a full-featured frontend for users to interact with the Lens blockchain, including wallet authentication, post creation and engagement (likes, comments, reposts, collects, tips), group management, notifications, and profile customization. The application uses React 19 with Vite for bundling, TypeScript for type safety, and Tailwind CSS for styling. State management combines Apollo Client for GraphQL data persistence with Zustand stores for client-side state (account, notifications, preferences). Key architectural patterns include optimistic UI updates for blockchain transactions, portal-based modals, and custom hooks for transaction handling and media uploads. The codebase demonstrates strong modularity with reusable UI components and clear separation between UI, state management, and data layers.
nOS Client is an Electron-based desktop application that serves as a wallet and decentralized application (dApp) browser for the NEO blockchain. It provides a virtual operating system metaphor with a built-in webview-based browser, account management, portfolio tracking, token transfers, and GAS claiming. The app integrates with the NEO network via neon-js, supports hardware wallets (Ledger) and mnemonic-based key management, and exposes a custom JavaScript API (NOS.V1) to dApps through a request processor. The codebase is organized as a standard React/Redux SPA with multiple feature modules (auth, browser, account, settings, appstore) and heavy use of higher-order components for state management. The application is feature-rich but shows its age: dependencies are heavily outdated (Electron 2.x, Webpack 3, React 16.8 with recompose), and some sections like Exchange and Favorites are incomplete placeholders. Despite this, the core wallet and dApp browsing functionalities are implemented with reasonable modularity, though the reliance on legacy patterns and unmaintained libraries makes it risky to reuse without modernization.
