Hi all,
A validator only earns while it works, and a monitor that runs on the same server goes down with it. So we built Madar Ops Pro: it watches a Polkadot or Kusama validator from outside your infrastructure, using public chain data only. All it needs is your stash address — no server access, no keys, no proxies, nothing to install.
What it alerts on
- Active in the session but earning no era points for 60 minutes (node down, out of sync, or session keys not matching)
- Chilled or blocked (no validator intention on Asset Hub)
- Not elected in the active era
- A slash recorded for your validator
- Commission changed (useful if staking keys are ever compromised)
- Unclaimed rewards a few eras before they expire
It reads both sides of the post–Asset Hub-migration layout: the relay chain (Session.Validators, StakingAhClient.ValidatorPoints) and Asset Hub staking (Validators, ErasStakersOverview, slashes, ClaimedRewards).
About the 60-minute threshold: we sampled ValidatorPoints for all 598 Polkadot validators every 4 minutes for an hour. Healthy validators regularly went 32 minutes without new points, and a few up to 48. A 30-minute rule would have woken up roughly one operator in five for nothing, so we use 60.
Alerts go to the ntfy phone app (we create a private topic), or to a Discord / Slack / Matrix webhook. One message when a problem starts, reminders while a critical one lasts, one message when it is resolved.
Pricing: 7-day free trial, then $15 per validator per month or $150 per year, paid in USDC or USDT on Solana, Base or Arbitrum, straight to our wallet. No card, no account; you manage the subscription with a key.
If you would rather self-host, the free and open-source Madar Ops (Apache-2.0) runs next to your node and watches it from the inside (disk, peers, sync, finality). Source: MADAR/ops at main · MADAR-NETWORK/MADAR · GitHub
