What we built

NodeWatch is a lightweight on-chain dashboard for monitoring blockchain validator and RPC node health across multiple networks — Ethereum, Solana, Base, Polygon, BNB Chain, Arbitrum, Optimism, and Avalanche.

Why

Node operators and dApp developers lack a simple, aggregated view of node health across chains. Most rely on scattered monitoring tools or centralized services. NodeWatch provides a clean, real-time dashboard that any node operator can use to track latency, uptime, and status — with on-chain verification of health data via smart contract.

How it works

  • Frontend (React + Recharts) displays real-time RPC node status with latency charts, health badges, and search/filter
  • Smart contract on OPN Chain (Chain ID 984) serves as an on-chain registry for node metadata, ping records, and uptime calculations
  • Anyone can query the contract for permissionless node health verification
  • Open source — full code available on GitHub for community contributions
  • Deployed demo at nodewatch-six.vercel.app with 8 major chains monitored

Roadmap

02/03

What ships next.

The builder's own next-quarter plan. Use it to gauge follow-through and ambition.

Phase 1 · Now (Q2 2026)

  • Deploy NodeWatch contract to OPN mainnet post-testnet verification
  • Expand to 15+ chains including L2s (zkSync, StarkNet, Linea, Scroll)
  • Add real-time WebSocket-based latency tracking instead of simulated data
  • Implement validator-level monitoring for Ethereum (consensus + execution layer)

Phase 2 · Q3 2026

  • Open public API endpoint for programmatic node health queries
  • On-chain oracle integration — publish aggregated health scores on-chain for other dApps to consume
  • Add alert system: Telegram/Discord webhook notifications when a node goes degraded or offline
  • Support user-defined custom RPC endpoints

Phase 3 · Q4 2026 & Beyond

  • Validator staking dashboard — track APR, missed blocks, governance participation
  • Decentralized monitoring network — incentivize community-run watchtower nodes
  • Mobile app (React Native) for on-the-go node health checks
  • DAO governance for node watcher rewards and protocol upgrades

On-chain proof

03/03

1 contract on OPN Chain.

The chain itself confirmed every deployment is valid, signed by the builder's wallet, and inside the season's window.
