SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Building a Solana mobile app involves unfamiliar territory: Mobile Wallet Adapter integration, crypto polyfills, custom Expo development builds, deep linking, and mobile-specific edge cases like network drops and app backgrounding during signing. This Skill walks a developer through the entire build phase with current Solana Mobile patterns. ## Core Features & Use Cases - Guided Mobile Build Workflow: Scaffolds from current Solana Mobile templates, integrates wallet connection (MWA, Phantom deep links, or embedded wallets), and implements the first transaction flow. - Wallet & Architecture References: Ships reference docs covering MWA authorization, Kit-based vs web3.js transaction patterns, polyfill setup, and signing UX best practices like timeouts and preflight checks. - Phase Handoff Context: Reads and writes .superstack/build-context.md so stack decisions (platform, wallet method, scaffold repo) persist across the Idea → Build → Launch journey. - Use Case: A developer says "build a mobile Solana dApp" and gets step-by-step guidance: scaffold with create-solana-dapp, set up react-native-quick-crypto polyfills, connect a wallet via MWA, sign a transaction, and verify on a physical device. ## Quick Start Ask the assistant to help you build a Solana mobile app with React Native and Mobile Wallet Adapter wallet connection.

Frequently Asked Questions about build-mobile

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a Solana mobile app with React Native?▼

Start with `npm create solana-dapp@latest` and choose a Solana Mobile React Native template. Add `react-native-quick-crypto` polyfills imported before any Solana libraries, then build a custom Expo development build with `npx expo run:android` since Expo Go does not support MWA.

What is Mobile Wallet Adapter and how do I use it?▼

Mobile Wallet Adapter (MWA) is the standard protocol for Solana mobile dApp-to-wallet communication, working with Phantom, Solflare, and other compatible wallets. Your app calls `transact()`, which opens the wallet app for user authorization and returns the signed transaction.

Should I use @solana/kit or @solana/web3.js for a React Native Solana app?▼

Kit is the preferred direction for new apps, following samples like skr-staking with `@wallet-ui/react-native-kit`. Web3.js remains a compatibility path where official docs or your chosen template still require it, but avoid mixing both stacks in one app.

Can I test Solana mobile wallet flows on an emulator?▼

Yes, use any Android device or emulator with the Mock MWA Wallet during development. However, final end-to-end verification must run on a physical device with a real wallet installed before calling the flow production-ready.

Why does wallet signing hang or time out on mobile?▼

MWA can hang if the user backgrounds the app or does not respond to the wallet prompt. Wrap signing calls in a timeout (around 120 seconds), listen to AppState changes to detect backgrounding, and show user-friendly error messages for rejections and expired blockhashes.

When should I use Phantom deep links instead of MWA?▼

Phantom deep links suit simple single-transaction connect-and-sign flows without a full SDK. They are less reliable, Phantom-only, and lack batch signing, so MWA is recommended for production apps.
