Feat/historical

[nafiuishaaq]

BridgeWise provides real-time quotes and transfers, but developers and dApp teams need historical performance insights to optimize bridge selection.

This issue introduces Historical Bridge Performance Metrics, tracking:

Bridge reliability over time
Average settlement times
Slippage trends
Fee patterns per route
Success/failure rates
This enables smarter route ranking, analytics dashboards, and proactive UX improvements.

🎯 Problem
Developers currently cannot evaluate which bridges perform best over time.
Slippage, fees, and failures may fluctuate, but historical trends are unavailable.
Decisions are based solely on real-time data, which may be suboptimal.
Lack of historical insights reduces trust and predictability.
Without historical metrics, BridgeWise cannot provide data-driven recommendations.

💡 Proposed Solution
Build a metrics collection and aggregation system that:

Stores per-bridge, per-route historical performance data
Aggregates data over configurable intervals (daily, weekly, monthly)
Exposes hooks and REST API endpoints for developers
Integrates with analytics dashboard (Issue #15) and ranking engine (Issue #5)
Supports visualization in SDK demo dashboard
🛠 Scope of Work
1️⃣ Define Historical Metrics Data Model
interface BridgePerformanceMetric {
bridgeName: string;
sourceChain: string;
destinationChain: string;
timeInterval: 'daily' | 'weekly' | 'monthly';
totalTransfers: number;
successfulTransfers: number;
failedTransfers: number;
averageSettlementTimeMs: number;
averageFee: number;
averageSlippagePercent: number;
timestamp: Date;
}
Standardized for all supported chains
Compatible with analytics and ranking engine
2️⃣ Implement Data Aggregation Pipeline
Aggregate transaction history (Issue #19)

Calculate:

Average settlement time
Average fees
Average slippage
Success/failure rates
Store aggregated results in database or local storage

3️⃣ Hooks and API Exposure
useBridgePerformanceMetrics() hook for React
REST API endpoint: GET /api/v1/bridge-performance-metrics
Supports filtering by bridge, route, and time interval
4️⃣ Dashboard Integration
Update demo analytics dashboard to show historical trends

Include charts for:

Slippage trends
Fee changes
Success/failure ratios
Support light/dark theme integration

5️⃣ Error Handling & Fallbacks
Handle missing or incomplete historical data gracefully
Provide empty state or fallback metrics
SSR-safe implementation for Next.js
📊 Expected Outcome
Developers can analyze bridge performance historically
Data-driven decisions for route selection and UX improvements
Improved reliability and user trust
Enhanced analytics dashboard functionality
✅ Acceptance Criteria

Historical metrics data model implemented

Data aggregation pipeline functional

useBridgePerformanceMetrics() hook implemented

REST API endpoint available

Dashboard visualizations implemented

Filterable by bridge, route, and interval

SSR-safe for Next.js

Unit tests covering aggregation, hook, and API

Documentation updated with usage examples
📈 Measurable Impact
Smarter route selection for developers
Increased user confidence in cross-chain transfers
Reduced reliance on real-time-only metrics

📚 Documentation Requirements
Add “Historical Bridge Performance Metrics” section to README
Provide hook usage example:
const metrics = useBridgePerformanceMetrics({ bridge: "StellarBridge", interval: "daily" });
Document API endpoint structure
Include visualization examples in demo dashboard
