Implement Solana RPC proxy with automatic failover and caching
- Add multi-provider support for 5 free Solana RPC endpoints (Alchemy, PublicNode, Helius, QuickNode, Solana Public)
- Implement automatic failover with 30-minute backoff for failed providers
- Add disk-based response caching with 100GB LRU eviction
- Create SQLite error logging with UUID tracking
- Support both HTTP JSON-RPC and WebSocket connections
- Include provider-specific authentication handling
- Add response normalization for consistent output
- Write end-to-end tests for core functionality
The proxy provides a unified endpoint that automatically routes requests to available providers, caches responses to reduce load, and logs all errors with retrievable UUIDs for debugging.
