📝 Walkthrough

Walkthrough

This PR removes a security workflow and introduces architecture and roadmap documentation. The architecture document outlines FrilChain's system design across Web, API, and Indexer services with planned communication flows. The roadmap defines a five-phase evolution from lightweight wallet explorer to a scalable blockchain data platform.

Documentation and Planning

Layer / File(s)	Summary
Architecture Overview docs/ARCHITECTURE.md	FrilChain architecture defined: Web client connects to Spring Boot API; data flows through Postgres, Redis Pub/Sub, and Rust JSON-RPC to blockchain nodes. Services documented with responsibilities and technologies. Communication mechanisms specified (REST, JSON-RPC, WebSocket, Redis Pub/Sub, planned Kafka). Early-phase database schema includes users, oauth_accounts, watchlists. Phased evolution outlined from wallet explorer to blockchain data platform.
Product Roadmap docs/ROADMAP.md	Five-phase product roadmap documented: Phase 1 covers wallet balances, ERC20 lookups, history, OAuth, watchlists; Phase 2 adds portfolio management and caching; Phase 3 enables real-time notifications via WebSocket/SSE; Phase 4 introduces selective wallet indexing with Rust service; Phase 5 scales to event-driven platform with Kafka and multi-chain support.

Poem

🐰 A workflow takes leave, docs bloom in its place,
Architecture and roadmap map the builder's base,
Five phases unfold—from explorer to scale,
The blockchain awaits, may FrilChain prevail! 🌿
