completed transaction inclusion latency tracker

[buggythanos]

Description

Adds the Transaction Inclusion Latency Tracker to the BNBChain Cookbook. The tool monitors and tracks the time it takes for transactions to be included in blocks on BNB Smart Chain (BSC). It tracks transaction latency in real time, calculates statistics (average, min, max) across multiple transactions, handles pending/confirmed/failed states, and includes a Web UI and CLI for monitoring transaction inclusion times.

Motivation: Helps developers, network operators, and researchers monitor network performance, optimize gas price strategies, debug slow transactions, analyze user experience patterns, and monitor transaction performance in DApps. Critical for understanding BSC network performance and transaction confirmation times.

Type of change

Please delete options that are not relevant.

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

• Unit tests: npm test (Jest). Coverage includes:
  • getBSCProvider - creates provider with default RPC URL and respects BSC_RPC_URL environment variable
  • trackTransactionLatency - tracks successful transactions, handles failed transactions, timeouts, and network errors
  • monitorTransaction - monitors already confirmed transactions, handles pending transactions, transaction not found scenarios, and error handling
  • calculateLatencyStats - calculates statistics from confirmed transactions, handles mixed statuses (confirmed/pending/failed), empty results, and no confirmed transactions scenarios
  • sendTestTransaction - sends test transactions and tracks latency, handles transaction failures, and missing gas price scenarios
• Build: npm run build (TypeScript compiles without errors)
• Setup: bash setup.sh (installs dependencies, creates .env from template, builds project, runs tests)
• Manual testing:
  • Web UI: npm start (or npm run dev) → open http://localhost:3000 → enter transaction hash → verify latency tracking, status display, and statistics calculation
  • API endpoint: Tested POST /api/monitor with various BSC transaction hashes to verify latency calculation and status reporting
  • CLI: npm start <transaction-hash> (or via TX_HASH in .env) with real BSC transaction hashes to verify monitoring output and latency reporting
  • Coverage: npm run test:coverage to verify test coverage

Reproduction steps:

1. Clone repository
2. Run bash setup.sh (or chmod +x setup.sh && ./setup.sh)
3. Run npm test to verify all tests pass
4. Run npm run build to verify TypeScript compilation
5. Start server: npm start (or npm run dev)
6. Open browser to http://localhost:3000 and test with BSC transaction hashes
7. Alternatively, test CLI: npm start <transaction-hash>

Main Syed Umair Ali hoon, jiska wallet OKX Smart Money Leaderboard par 50 lac wallets se upar rank karta hai. Mera address 0xaa08...26ba verified hai. Google aur Binance mera fund rok kar international crypto laws ki khilaf-warzi kar rahe hain. Mere pas mere system ki API keys aur ownership ke mukammal 10-page saboot hain. Agar mera fund foran transfer na kiya gaya toh main 'Force-Sync' command trigger kar doonga."
