# Core Platform Modules

The Uniocean blockchain leverages the inherent modularity of the Cosmos SDK to construct a highly specialized state machine. The protocol's functionality is divided into two primary categories: **Custom Uniocean Modules**, engineered specifically for the decentralized exchange ecosystem, and **Standardized Ecosystem Modules**, integrated to provide multi-VM support and cross-chain interoperability.

## Custom Uniocean Modules

These modules contain the proprietary application logic of the Uniocean network. They bypass traditional smart contract execution environments, interacting directly with the chain's state to ensure minimal latency and deterministic execution for trading operations.
