Uptime — GenLayer SLA Monitor

Trustless uptime monitoring for GenLayer infrastructure services. Health checks run on-chain via an Intelligent Contract; a public dashboard shows real-time status, uptime percentages, and SLA compliance.

Live: https://uptime.dev.genlayer.foundation

What it monitors

• ZKSync Bridge explorer
• Studionet RPC + Explorer
• Asimov RPC + Explorer
• Bradbury RPC + Explorer

How it works

1. A Vercel cron job calls the Intelligent Contract's run_checks() method at a configurable interval
2. The contract pings each service (JSON-RPC gen_dbg_ping for RPCs, HTTP GET for explorers) with validator consensus via gl.eq_principle.strict_eq()
3. Every check result is stored on-chain — trustless SLA proof
4. An off-chain cache (Vercel KV) syncs incrementally for fast dashboard loading
5. The public dashboard shows current status, uptime %, historical charts, and SLA compliance

The contract is deployed on studionet, asimov, and bradbury.
