Real-time sequencer health monitoring dashboard with block production graphs, inclusion histograms, and gas cost tracking.

Price: $14.99 | License: MIT | Category: Frontend | Runtime: Node.js 18+

Overview

sequencer-dashboard is a React dashboard for monitoring rollup sequencer health in real time. It displays block production rate, transaction inclusion latency distributions, gas cost trends, and sequencer uptime — all updated live via WebSocket connections to your L2 node.

Designed for rollup operators who need a heads-up display for their sequencer. Works with any OP Stack, Arbitrum, or EVM-compatible rollup.

Features

Real-time health monitoring — Live sequencer status with uptime tracking and block height
Block production graphs — Line charts of blocks per minute with anomaly highlighting
Transaction inclusion histograms — Distribution of submission-to-inclusion latency
Gas cost tracking — L1 batch posting costs and L2 gas utilization over time
WebSocket live updates — All metrics stream in real time, no polling
Responsive dark theme — CryptoForge branded UI with mobile-friendly layout
Configurable alerts — Visual + audio alerts for missed blocks or degraded health
