🌟 Overview

Solana prediction markets by using liquidity depth to determine market confidence and odds, rather than just token prices. The deeper the liquidity pool, the more confident the market prediction becomes.

🚧 Known Issues & Roadmap

Critical Priority (Must Fix Immediately)

Database Relationships

• Issue: Manual joins in lib/database-service-relationship-fix.ts instead of proper constraints
• Solution:

- Add foreign key constraints in Supabase schema - Update schema in scripts/001-initial-schema.sql - Remove manual join logic from service

• Files to Modify:

- scripts/001-initial-schema.sql - lib/database-service-relationship-fix.ts

Fee Distribution

• Issue: Unimplemented in lib/dlmm-real-fixed.ts
• Solution:

- Implement fee collection during swaps - Distribute fees proportionally to liquidity providers - Add fee tracking in database

• Files to Modify:

- lib/dlmm-real-fixed.ts - lib/database-service-fixed.ts - types/database-fixed.ts

Oracle Integration

• Issue: Limited to ETH/BTC/SOL markets in lib/dlmm-real-fixed.ts
• Solution:

- Make oracle symbol configurable per market - Add dynamic price feed resolution - Support custom target prices

• Files to Modify:

- lib/dlmm-real-fixed.ts - types/market.ts - programs/pool-odds/src/lib.rs

Token Mints

• Issue: Placeholder tokens in swap functionality (lib/dlmm-real-fixed.ts)
• Solution:

- Use real token mints from market configuration - Add token mint validation - Update swap transaction builder

• Files to Modify:

- lib/dlmm-real-fixed.ts - lib/transaction-service.ts - types/dlmm.ts

High Priority (Next Sprint)

• Service Consolidation: Competing fixed vs standard implementations
• Market Resolution: Complete for all market types
• Error Handling: Enhance recovery and consistency
• Configuration: Replace hardcoded values with config system

Medium Priority

• UI Loading States: Add skeletons and better loading indicators
• Market Stats: Tooltips and explanations
• Health Checks: Comprehensive system monitoring
• Testing: Expand test coverage

Low Priority (Technical Debt)

• Style System: Standardize CSS classes
• Error States: Improve UI for error conditions
• Fallbacks: Refine fallback mechanisms
• Logging: Enhance logging granularity
