Overview
Building mobile apps that interact with Solana goes far beyond connecting wallets. Your users want to transfer tokens, mint NFTs, execute swaps, and interact with programs, all from their phones. This course teaches you how to build these features with mobile-first considerations.
What You'll Learn
RPC Fundamentals
Understanding how your mobile app communicates with Solana is foundational. You'll learn:
How mobile RPC differs from web RPC
Setting up reliable connections on unreliable networks
Caching strategies to minimize requests and save battery
Choosing the right RPC providers for production
Token Operations
SPL tokens are the lifeblood of Solana DeFi. You'll build:
Token balance fetching with proper caching
Transfer flows with mobile-optimized UX
Associated Token Account management
Metadata display from various token standards
NFT Operations
NFTs require special handling for media, metadata, and collections:
Fetching NFT collections efficiently
Displaying NFT media (images, video, 3D) on mobile
Transfer and burn operations
Working with Metaplex standards
Blinks and Actions
Solana Actions and Blinks bring blockchain interactions to any surface:
Understanding the Actions specification
Building mobile-native Action clients
Rendering Blinks in your app
Security considerations for external Actions
Program Interaction
Direct program interaction gives you full control:
Building and signing arbitrary instructions
Working with Anchor IDLs on mobile
Transaction simulation for better UX
Error handling and retry strategies
Prerequisites
Before starting this course, you should have completed:
Mobile Wallet Adapter - Understanding MWA connection and authorization flows
MWA Deep Dive - Familiarity with transaction signing and session management
If you haven't completed those courses, we recommend starting there first.
Mobile-First Mindset
Every lesson in this course considers mobile constraints:
Network Reliability: Mobile connections drop. Your app needs to handle partial completions, retries, and offline states gracefully.
Battery Life: Constant polling drains batteries. We'll use websockets, webhooks, and smart caching instead.
Screen Real Estate: Complex transaction details need thoughtful presentation on small screens.
User Patience: Mobile users expect instant feedback. We'll use optimistic updates and clear loading states.
Development Setup
You'll need:
React Native or Expo project with MWA configured
Android device or emulator for testing
Wallet app installed (Phantom or Solflare)
Devnet SOL for testing transactions
If you completed the Mobile Wallet Adapter course, your environment is ready.
Course Structure
Each lesson builds on the previous:
RPC Fundamentals - Connection setup, commitment levels, and mobile optimizations
Token Operations - SPL token transfers, balances, and metadata
NFT Operations - Collections, media handling, and NFT transfers
Blinks and Actions - Solana Actions specification and mobile implementation
Program Interaction - Building custom instructions and working with Anchor
By the end, you'll have the skills to build feature-rich mobile dApps that interact with any Solana program.
Let's Begin
Start with RPC Fundamentals to understand how your mobile app communicates with the Solana network. This foundation will support everything else you build.
