What chain is Vulcan forge on?

Excuse me, could you please clarify which blockchain network Vulcan Forge is built upon? I'm curious to know if it's utilizing one of the major networks like Ethereum, Binance Smart Chain, or perhaps it's leveraging a lesser-known or proprietary blockchain technology. Understanding the underlying infrastructure is crucial in assessing the project's scalability, security, and potential for interoperability with other blockchain-based systems.
