zkSync Era RPC status

Is zkSync Era RPC down? Live status of the SwiftNodes zkSync Era endpoint, the latest block it is serving, and daily uptime measured by health checks every 2 minutes since 2026-08-25.

Uptime

“Online” means at least one of our zkSync Era upstream nodes passed its health check in that round; requests go to nodes that pass whenever any do. A day's figure is the share of rounds that were online.

Grey days (2026-09-19 to 2026-09-23) have no measurements: our status sampler was not recording then. They are gaps in the record, not outages, and are excluded from the uptime figures.

Endpoint, limits and measured developer facts: zkSync Era RPC. All chains: network status.
