Eyrium vs beaconcha.in: which validator alert service should you use?
Pick Eyrium if you want native Telegram + iOS/Android push, configurable noise control on missed-attestation alerts, and flat $7/mo pricing.
Pick beaconcha.in if you also need a full block explorer or broader on-chain analytics — they're a chain explorer with alerts bolted on. Eyrium is alerts-first.
beaconcha.in is the dominant Ethereum block explorer. It also offers validator monitoring and alerts on free and Premium tiers, with the Premium plan structured as a base subscription plus per-validator-count add-ons (up to €359.99/mo for the largest stakers). Eyrium is alerts-first: a focused validator monitoring product at a flat $7/month for up to 200 validators, with notification channels and noise controls beaconcha.in doesn't ship.
Here's how they actually compare.

Where Eyrium wins
1. Flat, predictable price. Eyrium Pro is $7/mo. No tier ladder, no per-validator-count add-ons, no separate webhook quota. beaconcha.in Premium scales by validator count via add-ons, with large-staker tiers reaching €359.99/mo. If you're a solo home staker or running a fleet up to 200 validators, the flat-rate math is hard to argue with.
2. Telegram delivery without third-party glue. beaconcha.in sends alerts to webhooks; if you want Telegram, you wire up your own bot. Eyrium has a native Telegram bot — you /start it, paste a one-time verification code, done.
3. Configurable streak threshold on missed attestations. Missed-attestation alerts can be noisy — head-only misses, propagation timing, peering hiccups all fire alerts. Eyrium lets you set a streak threshold (1–10) per account, so you only get pinged when the misses are consecutive enough to matter. beaconcha.in's public notification config doesn't appear to expose a streak threshold setting.
4. Head-only-miss suppression. When only the head vote is missed but target and source landed, the cause can be block propagation or inclusion timing. Eyrium can suppress these alerts entirely. beaconcha.in does not appear to offer this filter.
5. Fee-recipient and withdrawal-credentials change alerts. This is a supply-chain alert: if someone (or some compromised tool) changes where your rewards go, you want to know. Withdrawal-credential changes are caught when the finalized checkpoint advances; the fee recipient is verified on every block your validator proposes, and any change fires the alert. beaconcha.in does not advertise this alert type.
Where beaconcha.in wins
1. Block explorer. If you spend time looking at block details, attester duties, fork rates, sync committee assignments, or general Ethereum chain analytics, beaconcha.in is a full explorer. Eyrium is not — we monitor validators, we don't show you the chain.
2. Multi-chain coverage. beaconcha.in covers Ethereum and (for now) Gnosis. Eyrium is Ethereum-only.
3. Maturity. beaconcha.in has been the default validator dashboard since the Beacon Chain launched. If you value a long track record over feature focus, that matters.
When to switch
Switch to Eyrium if
- You're tired of missed-attestation alert volume
- You want Telegram or native mobile push without setup work
- You want a flat, predictable price as your validator count grows
- You want fee-recipient change alerts as a supply-chain safeguard
Stay on beaconcha.in if
- You actively use the block explorer features
- You need broader chain-wide analytics
- You need Gnosis Chain coverage
- Webhook-only notification fits your existing stack
There's no reason you can't use both — beaconcha.in's free tier is fine as a chain explorer, Eyrium handles the alerting categories it covers.
FAQ
- How much does Eyrium cost compared to beaconcha.in Premium?
- Eyrium is a flat $7/mo (or $70/yr) for up to 200 validators. beaconcha.in Premium is tiered — a base subscription plus per-validator add-ons that scale up to €359.99/mo for the largest stakers. Exact base prices vary by tier; check beaconcha.in for current numbers.
- Can I monitor more than one validator on Eyrium's free tier?
- No. Free tier is 1 validator with email-only alerts. Pro ($7/mo) lifts that to 200 validators and adds Telegram and native push.
- How fast are Eyrium's slashing alerts?
- Eyrium evaluates validator state whenever Ethereum's finalized checkpoint advances. Once a slashing transition is detected, configured notifications are queued immediately.
- Does Eyrium support missed-proposal or sync-committee alerts?
- Yes. Eyrium pages you on email, Telegram, or push when an assigned proposal slot goes empty or a sync-committee signature is missed. Successful proposals and current or upcoming sync-committee assignments are also recorded in the event feed.
- Does Eyrium support Discord, Slack, SMS, or webhooks?
- Not today. Currently shipping: email, Telegram, iOS push, Android push, plus a read-only REST API for your validators' state, events, and rewards. Webhooks are on the roadmap.
- Does Eyrium have an API?
- Yes — a read-only REST API covering your own validators: current state, alert events, and per-epoch rewards with ideal-reward comparison. Included on both the free tier and Pro at no extra cost, with API keys managed in Settings. It is not a chain-explorer API: it returns your validators' data only. Docs at eyrium.app/docs/api.
- Can I use beaconcha.in and Eyrium together?
- Yes — many users do. beaconcha.in is a chain explorer with alerts; Eyrium is focused alerting with noise controls. Use beaconcha.in for browsing chain data and Eyrium for attestation, proposal, sync-committee, and supply-chain alerting.
- What if I have more than 200 validators?
- Contact us at [email protected]. The 200 cap is a soft cap on the standard Pro plan — we can accommodate larger operators.
