Sparky is an independent Flare infrastructure operator, run by a seasoned team that has operated blockchain validators for 8+ years. We run a full validator and a complete Flare Entity with an FTSO data provider and an FDC attestation provider — fully self-hosted and continuously monitored.

Our goal is simple: maximum uptime, accurate data, and infrastructure you don’t have to think about. No outsourced node management, no shared tenancy on someone else’s stack. Every layer — from hardware to alerting — is owned and operated directly by us.

Operated by Sparky Consulting GmbH, registered in Zürich, Switzerland.
