# L2 as a Communication Layer

**Optimex** introduces a dedicated **Layer 2 (L2)** to coordinate interactions between key participants, ensuring transparency and security across the system. The L2 records **DeFi activities**, manages **Settlement Nodes’ security deposits**, and enforces **slashing penalties** for protocol violations.

In most cases, users do not need to interact with the L2 directly. Instead, it serves as a **backend coordination layer** for **Validation Network Nodes, Market Makers, and other stakeholders**, ensuring a **shared system view** and enforcing **economic security** against bad actors.
