Evedex Layer 3 technology and trading system explanation

I recently saw a description of a trading platform that mentioned it is built on something called Layer 3, and I realized I don’t fully understand what that means. I’ve heard about Layer 2 solutions before, but this sounded like another step. The article also talked about a custom rollup and its own matching engine, which made it even more technical. I’m trying to figure out how these elements actually affect trading from a user perspective. There was also mention of modular structure, separating trading, risk management, and interface components. It feels like an advanced setup, but I’m not sure how it translates into everyday use. Has anyone tried to break this down in simpler terms?
