+## Project Structure & Focus Areas
+This is a Zeitgeist blockchain project monorepo with the following components:
+- `zeitgeist-runtime/` - Substrate runtime (**REFERENCE ONLY - NO MODIFICATIONS**)
+- `zeitgeist-sdk/` - TypeScript SDK for blockchain interactions (active development)  
+- `zeitgeist-subsquid/` - GraphQL indexer using Subsquid framework (active development)
+- `zeitgeist-ui/` - Frontend application (primary focus)

-## Code Style and Structure
+## General Coding Standards
+
+### TypeScript/JavaScript
+- Use TypeScript for all code; prefer interfaces over types
 - Write concise, technical TypeScript code with accurate examples
 - Use functional and declarative programming patterns; avoid classes
 - Prefer iteration and modularization over code duplication
-- Use descriptive variable names with auxiliary verbs (e.g., isConnecting, hasBalance, isTrading)
-- Structure files: exported component, subcomponents, helpers, static content, types
-- Separate blockchain logic into custom hooks and utility functions
-
-## Naming Conventions
-- Use lowercase with dashes for directories (e.g., components/market-card, hooks/use-zeitgeist)
-- Favor named exports for components
-- Use Zeitgeist/Polkadot specific naming (e.g., marketId, assetId, blockNumber, extrinsic)
-
-## TypeScript Usage
-- Use TypeScript for all code; prefer interfaces over types
+- Use async/await patterns for blockchain interactions
 - Define strong types for Zeitgeist markets, assets, and blockchain responses
 - Avoid enums; use maps for market status, asset types, etc.
 - Use functional components with TypeScript interfaces
+- Modern ES6+ patterns and syntax
 - Type blockchain responses and SDK return values properly
 
-## Blockchain Integration
-- Always handle wallet connection states and network switching
-- Implement proper loading states for blockchain operations
-- Use defensive programming for blockchain data (null checks, fallbacks)
-- Implement retry logic for failed transactions or network issues
-- Handle different account formats (SS58, hex) appropriately
-
-## Syntax and Formatting
+### Code Quality & Structure
+- Write self-documenting code with clear intent
+- Use descriptive variable names with auxiliary verbs (e.g., isConnecting, hasBalance, isTrading)
+- Structure files: exported component, subcomponents, helpers, static content, types
+- Separate blockchain logic into custom hooks and utility functions
+- Keep functions small and focused (single responsibility)
+- Use early returns to reduce complexity
 - Use the "function" keyword for pure functions
 - Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements
-- Use declarative JSX
-- Format large numbers and token amounts for user display
-
-## UI and Styling
-- Implement responsive design with Tailwind CSS; use a mobile-first approach
-- Design for prediction market UX: clear odds display, intuitive trading flows
-- Use appropriate loading states for blockchain operations
-- Implement proper error states and user feedback for transactions
-
-## Performance Optimization
-- Wrap client components in Suspense with fallback
-- Use dynamic loading for non-critical components
-- Cache blockchain data to reduce API calls
-- Debounce user inputs for real-time price updates
-
-## Key Conventions
-- Use Jotai for global state management
-- Use 'nuqs' for URL search parameter state management
-- Use custom hooks for Zeitgeist SDK interactions (e.g., useMarkets, useBalance, useTrading)
-- Implement proper wallet connection and account management
-- Follow Zeitgeist's market lifecycle patterns (Created → Active → Closed → Reported → Resolved)
-- Handle different market types (Categorical, Scalar) appropriately

+
+## Cross-Project Integration
+
+### Blockchain Integration Patterns
+- **Always handle wallet connection states and network switching**
+- **Implement proper loading states for blockchain operations**  
+- **Use defensive programming for blockchain data (null checks, fallbacks)**
+- **Implement retry logic for failed transactions or network issues**
+- **Handle different account formats (SS58, hex) appropriately**

+- **Use SDK's TypeScript types throughout the UI**
+- **Handle SDK errors gracefully with user-friendly messages**
+- **Use BigNumber.js or similar for precise token calculations (avoid floating point)**
+
+### Subsquid ↔ UI Integration  
+- **UI should query Subsquid GraphQL endpoint for historical data**
+- **Use code generation for GraphQL types (graphql-codegen)**
+- **Implement proper caching strategies**
+- **Handle GraphQL errors and loading states**
+
+### Runtime ↔ SDK/UI Integration
+- **SDK should reflect runtime's pallet structures**
+- **Keep SDK types in sync with runtime types** 
+- **SDK methods should match runtime extrinsic signatures**
+- **Use runtime understanding to build proper extrinsic calls**
+- **Map Rust storage structures to frontend data models**
+- **Handle codec encoding/decoding for storage queries**

+
+## Development Workflow
+
+### Git Practices
+- Use conventional commits (feat:, fix:, docs:, refactor:, test:)
+- Create feature branches from main/develop
+- Include relevant project prefix in commit messages when changes span multiple projects
+- Example: `feat(ui): add market creation form` or `fix(sdk): handle connection timeouts`
+
+### Code Reviews
