What network is SNX on?

Could you please elaborate on the underlying network that the Synthetix Network Token (SNX) is based on? As a cryptocurrency enthusiast, I'm particularly interested in understanding the technical underpinnings and infrastructure that support this innovative decentralized finance project. Specifically, is SNX built on Ethereum, or does it utilize a different blockchain technology? Understanding the network foundation is crucial for assessing the scalability, security, and interoperability of the Synthetix platform. Thank you for your insight into this matter.
