Know your RPC node is down before your users do.
UptimeChain checks your blockchain endpoints around the clock and sends an alert to your phone the moment a node goes offline, stalls or slows down.

Each node is checked on a schedule and the result is stored in your history.
Set up in three steps
No servers to install. Add an endpoint and UptimeChain does the checking.
Add your endpoint
Paste the RPC URL for each network you run or depend on.
We check it on a schedule
Every check confirms the node answers and that the latest block number is moving.
Get alerted and see the history
You are notified when a node fails, and told again when it recovers.
What it watches
- Availability. Does the endpoint respond at all?
- Block height. Is the node still syncing new blocks, or has it stalled?
- Response time. Is the node slow enough to hurt your app?
- Networks. Ethereum, Polygon and Arbitrum, on mainnet and testnet.
What you get
- Instant alerts. Push notifications to your phone when a node fails.
- Auto-resolve. Alerts close themselves when the node recovers.
- Alert history. See every outage with start time and duration.
- Status page. One screen showing every node at a glance.
