What is iAccess?

Can you tell me more about iAccess? I'm interested in understanding what it is and how it works. I've heard it mentioned in the context of cryptocurrency and finance, but I'm not entirely sure what its purpose or function is. Could you provide a brief overview, including any notable features or benefits it offers to users in this field? Additionally, I'd like to know if it's widely used or if it's still relatively new and emerging in the market.
