📈 Implement Historical Bridge Performance Metrics

[mijinummi]

🧭 Overview

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 Hop Protocol Adapter Backend Module #15) and ranking engine (Issue [DevOps] Setup Monorepo Documentation via Storybook #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
• Enhanced analytics capabilities

---

🧪 Testing Requirements

• Simulate historical transactions across multiple bridges and chains
• Validate aggregation calculations
• Test hook and API outputs for different time intervals
• Confirm dashboard charts display correct historical trends
• Test SSR-safe rendering and empty/fallback states

---

📚 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
