What is Nodal Exchange?

Could you please elaborate on the nature and purpose of Nodal Exchange? I'm curious to understand how it fits into the broader cryptocurrency and finance landscape. Specifically, I'm interested in knowing if it's a trading platform, an exchange service, or perhaps a financial institution. Furthermore, what are its key features and how does it aim to distinguish itself from other similar platforms? Additionally, could you provide insights into its regulatory compliance, security measures, and the types of cryptocurrencies it supports? Your input would greatly assist me in gaining a comprehensive understanding of Nodal Exchange.
