About this app

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.

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

See what your validators are doing:
• 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
• Never accesses signing keys, withdrawal keys, or mnemonics
• Public on-chain data only

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

Eyrium is validator monitoring, not node monitoring: it watches the chain, so it sees missed duties, slashing and exits, but it cannot tell you your disk is full or a client process died. Keep your local monitoring; this sits alongside it. Ethereum mainnet only.

The free tier monitors one validator with email alerts. Eyrium Pro raises the limit to 200 validators and adds Telegram, native push, and webhooks.
