Solana Game Development Skill

Extends: solana-dev-skill - Core Solana development (programs, frontend, testing, security)

What This Skill Is For

Use this skill when the user asks for:

Unity Game Development

• Unity game development with Solana integration
• Wallet connection in Unity (Phantom, Solflare, InGame, Web3Auth)
• NFT loading, display, and game asset integration
• Transaction building and signing in C#
• PlaySolana/PSG1 console development

Mobile Game Development (React Native)

• React Native mobile games with Solana
• Mobile Wallet Adapter integration
• Offline-first game architecture
• Deep linking with Solana wallets
• Cross-platform iOS/Android development

Web Frontend (Gaming Context)

• Next.js/React frontends with Solana
• Wallet connection with framework-kit
• NFT galleries and game UIs
• Transaction UX patterns

Game Architecture

• On-chain vs off-chain game state
• Player progression and achievements
• Token economics and in-game currencies
• Multiplayer architecture with blockchain validation

Program Development (Delegate to Core Skill)

• For Anchor programs → programs-anchor.md
• For Pinocchio programs → programs-pinocchio.md
• For IDL/codegen → idl-codegen.md

Default Stack Decisions (Opinionated)

1) Unity Games: Unity 6000+ LTS

• Solana.Unity-SDK 3.1.0+ via UPM
• Modern Input System, UI Toolkit
• .NET 9 / C# 13
• Assembly definitions for organization

2) Mobile Games: React Native 0.76+ with Expo

• Mobile Wallet Adapter 2.x
• Zustand 5.x for state
• MMKV 3.x for storage
• TanStack Query 5.x for RPC data

3) Web: framework-kit first

• @solana/client + @solana/react-hooks
• @solana/kit for transactions
• Next.js 15 with App Router

4) Testing

• Unity: Edit Mode + Play Mode tests
• React Native: Jest + RNTL + Detox
• Web: Vitest + React Testing Library
• Programs: LiteSVM, Mollusk, Surfpool (see core skill)

5) Platform Targets

• Default: Desktop (Windows/macOS) and WebGL
• Mobile: When explicitly specified
• PSG1: When explicitly targeting PlaySolana

Operating Procedure

1. Classify the Task Layer

Layer	Examples	Skill File(s)
Unity/C#	Game mechanics, UI, wallet	unity-sdk.md, csharp-patterns.md
Mobile/RN	Mobile apps, MWA, offline	mobile.md, react-native-patterns.md
Web/Frontend	Next.js, React, wallet	frontend-framework-kit.md
Game Architecture	On-chain state, economics	game-architecture.md
Program/Anchor	On-chain game logic	programs-anchor.md
Program/Pinocchio	High-perf programs	programs-pinocchio.md

2. Pick the Right Agent

Task Type	Agent	Model
High-level design	game-architect	opus
Unity code	unity-engineer	sonnet
Mobile code	mobile-engineer	sonnet
Learning/tutorials	solana-guide	sonnet
Documentation	tech-docs-writer	sonnet

3. Apply Platform-Specific Patterns

Unity:

• Use WalletService pattern with events
• TransactionBuilder for building transactions
• NFTService with texture caching
• Async/await for all blockchain operations

React Native:

• Mobile Wallet Adapter for wallet connection
• Zustand stores for game state
• MMKV for offline persistence
• Network-aware sync patterns

Web:

• framework-kit hooks for wallet/balance
• React Query for RPC data
• Zustand for app state
• Kit types for transactions

4. Add Tests

• Unity: Edit Mode for logic, Play Mode for MonoBehaviours
• React Native: Component tests, hook tests, E2E
• Web: Component tests, hook tests
• Programs: LiteSVM/Mollusk (see testing.md)
• Two-strike rule: If test fails twice, STOP and ask

5. Deliverables

When implementing changes, provide:

• Exact files changed with clear diffs
• Package dependencies (manifest.json, package.json)
• Build/test commands
• Platform considerations
