## What is Eyrium?

Eyrium watches your Ethereum validators so you don't have to refresh beaconcha.in at 2am.

Add a validator by index, pubkey, or explorer link, then get push notifications when something needs your attention. Built for solo stakers and small operators who actually run their own nodes.

What Eyrium alerts you about:
• Missed attestations (with configurable streak threshold)
• Missed block proposals
• Missed sync-committee signatures and recovery
• Slashings
• Status changes (active → exiting → withdrawn)
• Balance drops
• Fee-recipient or withdrawal-credentials changes

What you can see:
• 7-day attestation effectiveness and missed reward value
• Rolling earnings and uptime
• Recent attestation and event history
• Active or upcoming sync-committee assignments

Designed for operators, not flippers:
• Add and remove validators in the app or on the web — the index is checked on-chain before it's saved
• Threshold controls so a single missed attestation during a node restart doesn't wake you
• "Ignore head-only misses" — alert only when the penalised source or target vote is missed
• Email + Telegram + native push, all toggleable per event type
• No validator signing keys, withdrawal keys, or mnemonics — ever
• Public on-chain data only

Privacy first:
• No analytics SDKs, no ad SDKs, no trackers in the app
• Push token + device name only; nothing else collected

Free tier monitors one validator. Eyrium Pro is available monthly or annually in the app and covers up to 200 validators plus Telegram and native push delivery.
