- Updated branding from "SolaceScanScout" to "Solace" across various files including deployment scripts, API responses, and documentation. - Changed default base URL for Playwright tests and updated security headers to reflect the new branding. - Enhanced README and API documentation to include new authentication endpoints and product access details. This refactor aligns the project branding and improves clarity in the API documentation.

# Tiered Architecture Implementation Summary
|
|
|
|
## Overview
|
|
|
|
The SolaceScan Explorer has been successfully upgraded to a 4-track tiered architecture with feature-gated access control.
|
|
|
|
## Implementation Status: ✅ COMPLETE
|
|
|
|
All components have been implemented according to the plan:
|
|
|
|
### ✅ Phase 1: API Contracts & Feature Flag System
|
|
- **API Contracts**: Complete documentation for all 4 tracks (`docs/api/track-api-contracts.md`)
|
|
- **Feature Flag Matrix**: Comprehensive mapping (`docs/feature-flags/track-feature-matrix.md`)
|
|
- **Feature Flag System**: Backend implementation (`backend/featureflags/flags.go`)
|
|
- **Feature Flags API**: Endpoint at `/api/v1/features`
|
|
|
|
### ✅ Phase 2: Authentication & Authorization
|
|
- **Wallet Authentication**: Signature-based auth with nonce (`backend/auth/wallet_auth.go`)
|
|
- **Role Management**: Track assignment and approval (`backend/auth/roles.go`)
|
|
- **Auth Middleware**: JWT validation and track extraction (`backend/api/middleware/auth.go`)
|
|
- **Auth Endpoints**: `/api/v1/auth/nonce` and `/api/v1/auth/wallet`
|
|
|
|
### ✅ Phase 3: Track 1 Hardening (Public Explorer)
|
|
- **RPC Gateway**: Caching and rate limiting (`backend/api/track1/rpc_gateway.go`)
|
|
- **Track 1 Endpoints**: All public endpoints implemented (`backend/api/track1/endpoints.go`)
|
|
- **Rate Limiter**: In-memory implementation (`backend/api/track1/rate_limiter.go`)
|
|
- **Cache**: In-memory cache with TTL (`backend/api/track1/cache.go`)
|
|
- **Security Middleware**: CSP headers and write-call blocking (`backend/api/middleware/security.go`)
|
|
|
|
### ✅ Phase 4: Track 2 (Full Indexed Explorer)
|
|
- **Indexers**: Block, transaction, and token indexers (`backend/indexer/track2/`)
|
|
- **Track 2 API**: All endpoints implemented (`backend/api/track2/endpoints.go`)
|
|
- **Database Schema**: Full Track 2-4 schema plus shared-DB-safe auth/operator subset (`backend/database/migrations/0010_track_schema.up.sql`, `backend/database/migrations/0010_track_schema.auth_only.sql`)
|
|
|
|
### ✅ Phase 5: Track 3 (Analytics)
|
|
- **Analytics Engine**: Flow tracking, bridge analytics, token distribution (`backend/analytics/`)
|
|
- **Track 3 API**: All analytics endpoints (`backend/api/track3/endpoints.go`)
|
|
|
|
### ✅ Phase 6: Track 4 (Operator Tools)
|
|
- **Operator APIs**: All operator endpoints (`backend/api/track4/endpoints.go`)
|
|
- **Security**: IP whitelist and audit logging integrated
|
|
|
|
### ✅ Phase 7: Frontend & Integration
|
|
- **Frontend Feature Gating**: Wallet connect UI and track-based feature visibility (`frontend/public/index.html`)
|
|
- **Route Integration**: Track-aware routing structure (`backend/api/rest/routes.go`)
|
|
|
|
## Architecture
|
|
|
|
```
|
|
Frontend (SPA)
|
|
├── Public (Track 1) - No auth required
|
|
├── Approved Users (Track 2) - Wallet auth required
|
|
├── Analytics Users (Track 3) - Track 3+ required
|
|
└── Operators (Track 4) - Track 4 + IP whitelist
|
|
|
|
Backend
|
|
├── Track 1: RPC Gateway + Cache + Rate Limiting
|
|
├── Track 2: Indexed Database (PostgreSQL)
|
|
├── Track 3: Analytics Engine (Materialized Views)
|
|
└── Track 4: Operator APIs (Audit Logged)
|
|
```
|
|
|
|
## Key Files Created
|
|
|
|
### Documentation
|
|
- `docs/api/track-api-contracts.md` - Complete API contracts
|
|
- `docs/feature-flags/track-feature-matrix.md` - Feature mapping
|
|
|
|
### Backend
|
|
- `backend/featureflags/flags.go` - Feature flag system
|
|
- `backend/auth/wallet_auth.go` - Wallet authentication
|
|
- `backend/auth/roles.go` - Role management
|
|
- `backend/api/middleware/auth.go` - Auth middleware
|
|
- `backend/api/middleware/security.go` - Security headers
|
|
- `backend/api/track1/` - Track 1 implementation
|
|
- `backend/api/track2/` - Track 2 implementation
|
|
- `backend/api/track3/` - Track 3 implementation
|
|
- `backend/api/track4/` - Track 4 implementation
|
|
- `backend/indexer/track2/` - Track 2 indexers
|
|
- `backend/analytics/` - Analytics engine
|
|
|
|
### Database
|
|
- `backend/database/migrations/0010_track_schema.up.sql` - full Track 2-4 schema
|
|
- `backend/database/migrations/0010_track_schema.auth_only.sql` - shared Blockscout DB auth/operator subset
|
|
|
|
### Frontend
|
|
- Updated `frontend/public/index.html` with feature gating
|
|
|
|
## Next Steps
|
|
|
|
1. **Run Database Migrations**:
|
|
```bash
|
|
cd explorer-monorepo
|
|
bash scripts/run-migration-0010.sh
|
|
```
|
|
The helper auto-detects standalone explorer DB vs shared Blockscout DB and chooses the safe migration path automatically.
|
|
|
|
2. **Configure JWT Secret**:
|
|
- Update `backend/api/rest/auth.go` to use environment variable for JWT secret
|
|
- Set `JWT_SECRET` environment variable
|
|
|
|
3. **Set Up Redis** (Optional, for production):
|
|
- Replace in-memory cache and rate limiter with Redis implementations
|
|
- Update `backend/api/track1/cache.go` and `rate_limiter.go`
|
|
|
|
4. **Configure RPC Gateway**:
|
|
- Set `RPC_URL` environment variable for Track 1 RPC gateway
|
|
|
|
5. **Approve Users**:
|
|
- Use `backend/auth/roles.go` to assign track levels to users
|
|
- Add IP addresses to whitelist for Track 4 operators
|
|
|
|
6. **Start Indexers**:
|
|
- Run Track 2 indexers to populate indexed data
|
|
- Start with backfilling historical blocks
|
|
|
|
## Testing
|
|
|
|
Test each track level:
|
|
- **Track 1**: Access without authentication
|
|
- **Track 2**: Connect wallet, get approved, access indexed data
|
|
- **Track 3**: Access analytics endpoints
|
|
- **Track 4**: Access operator endpoints (requires IP whitelist)
|
|
|
|
## Notes
|
|
|
|
- All implementations use in-memory cache/rate limiter - replace with Redis for production
|
|
- JWT secret is hardcoded in auth.go - move to environment variable
|
|
- Track routes are commented in routes.go - uncomment and wire up middleware when ready
|
|
- Frontend feature gating is implemented but needs testing with actual API responses
